OVERVIEW
Replica plastic owls and fake owl decoys are one of the most commonly used bird scaring devices to scare pigeons and other pest species of birds from their perching and roosting sites, predominantly on buildings in town and city centre environments. Fake owl decoys are normally mounted on roof areas where the product can be clearly seen by problem birds as they approach their roosting or perching areas. Replica plastic owls are also often sited in key and sensitive areas on buildings where pigeons are causing specific problems. These areas could be canopies in front of shops or railway stations, or possibly architectural features on period properties where pigeons are causing extreme problems as a result of soiling.
Bird scarer devices and replica plastic owls, are normally life size models of real owls and stand approximately 12″-23″ high depending on which product is chosen and which species of owl is being replicated. The quality of the reproduction varies considerably with some models looking quite life-like and others looking little or nothing like a real owl. A majority of fake plastic owl decoys have no moving parts, although there are now some models on the market like the Rotating Head Owl that move with air currents. Some of the more advanced owl scarers actually move on a rail whilst flapping their wings and making a hooting sound.
Replica Plastic Owl
Fake Owl Decoy
The principle of using a plastic owl decoy as a bird scarer is to use the pest birds instinctive fear of predators and predation to scare the bird away from its desired roosting, perching or breeding areas.
According to manufacturers and distributors claims, the replica plastic owl can be used to scare a wide variety of different species of pest birds in both urban and agricultural environments.
The product is completely humane which will have great appeal for those requiring a non-lethal or non-violent product and the fake plastic owl decoy is also relatively inexpensive to buy.
DEFRA’s view:
The Department of the Environment, Food and Rural Affairs (DEFRA) is the UK’s Government body that oversees the Wildlife and Countryside Act and produces legislation to which the pest control industry must adhere. The following information is taken from a document provided on DEFRA website entitled: ‘Review of international research regarding the effectiveness of auditory bird scaring techniques and potential alternatives’. By J Bishop, H McKay, D Parrott and J Allan.
“The basis for this scarer is mimicry of real predators and evocation of fear and avoidance in the target species. Most potential prey species react to predator models; the strength of the response, however, varies between species (Conover 1979) and in some cases raptor models can attract rather than repel birds as species like blackbirds and crows often mob owls and owl models (Conover 1983 cited in Harris and Davis 1998).”
“Model raptors fail to incorporate behavioural cues, which may be critical to the induction of fear and avoidance in the target species. Falcons which are “in the mood to hunt” are said to be “sharp set”; such birds are invariably hungry enough to fly at quarry. Although it is hard for human observers to differentiate between a falcon when it is sharp set and conversely well fed, birds will mob a hawk more frequently when sharp set than when well fed. Thus, model raptors will be inherently less threatening and subsequently less effective than live raptors (Inglis 1980).”
“In general, raptor models are inexpensive (£5- £25 for plastic owl models) and easy to deploy. However, birds quickly learn that the model poses no threat and rapidly habituate to it.”
Price range:
Prices for replica plastic owls vary considerably and currently range from £15 through to £25, but the cost is dependent on whether the owl is static (i.e. no moving parts) or whether it has wing, eye or head movement. Some of the more advanced robotic owls cost several hundred pounds and this does not include the cost of installation.
User reviews:
Alistair Brenning, Wales
“Had pigeons sitting on my fence. The owl worked in that it scared them off but eventually they came back.”
Comments from the Manufacturer/Distributor:
The following quotes from those involved with the bird control industry in the USA appear to sum up the general consensus on this product:
Barry Neer, a salesman at Nixalite of America Inc., a company that sells bird scarers said:
“The feedback we get from most customers is that within a few days the birds are sitting right on top of the owl.”
Michael Gelder, owner of Bay Area Bird Control in San Carlos, California said:
“If I see one (plastic owl),” he says “I know that the building still needs attention.”
Bird Barrier America Inc., also based in California, commented:
“There are two ways that replica plastic owls can actually be used as bird deterrents, a) throw the owl hard at them and b) physically block access to the area with the owl.”
In contrast to these views, Neal Caldwell, owner of Dalen Products Inc., of Knoxville, Tennessee, a manufacturer of replica plastic owls, suggests that negative views from within the pest control industry are simply competitive grousing.
Caldwell goes on to say:
”The owl seems to be effective wherever we put them.”
Editorial comments:
Fake owl decoys have received a considerable amount of negative publicity in relation to their effectiveness as a bird deterrent and bird scarer, but sales of the product appear to be consistently high. This may be as a result of the fact that the product is extremely inexpensive to buy and if, once installed, it proves to be ineffective the purchaser may feel that complaining to the retailer is a wasted effort.
Replica Plastic Owl
Fake Owl Decoy
DEFRA’s research clearly suggests that in some cases replica plastic owls can actually attract pest species of birds rather than deter them. DEFR also confirms that the product will only have limited success with some, rather than all species of bird. Where live raptors are flown to deter pest species of birds they are regularly mobbed by the target species, particularly gulls and members of the corvid family (crows, rooks etc). This fact alone suggests that a static plastic owl decoys will have little success in its own right. The owl is a very efficient predator, but it not the natural predator of the gull or the pigeon. In a vast majority of cases plastic owl decoys will be sold to those experiencing problems with these species and as a result the product is likely to fail unless it is provided as part of a comprehensive control system. Even then there is doubt as to whether the fake plastic owl can or will play any useful part.
Both DEFRA’s view, and that of the pest control industry, appears to be the same – the product is ineffective in anything but the very short-term. This may be as a result of the fact that a majority of fake plastic owls are static deterrents with no moving parts and therefore birds will become habituated to them extremely quickly. Broadly speaking, any deterrent that does not move or emit any type of sound or noise is likely to be ignored by many of the most common pest species of birds. There are bird scarer devices available that have moving parts such as moving eyes, head and wings, and some that even make a screeching sound as well, but although these products may have some limited success with timid garden birds such as blackbirds, they are unlikely to play any useful part in a control system designed to resolve an entrenched bird-related problem. It is also clear that although claims are made by both distributor and manufacturer alike that replica plastic owls will be effective in deterring a wide variety of pest species of birds, the reality is that the most common pest species (gulls and pigeons) will remain undeterred by this product.

Fake Owl Decoy
The major benefit of this product is that it is inexpensive and relatively simple to install and therefore, if it fails, it can be replaced without too great a loss to the property owner concerned. It should always be understood, however, that there are no ‘quick fixes’ where effective bird management is concerned and if a product or service appears to be ‘too good to be true’, there is a very good chance that it is. Industry standard products such as the anti-roosting spike continue to be the only really effective stand-alone deterrent available to most property owners and in light of this, restricted pest control budgets may be better spent on tried and tested products rather than their ‘quick fix’ counterparts.

Daddi Long Legs
OVERVIEW
The Daddi Long Legs anti-bird device is a unique and versatile anti-perching device that will protect virtually any surface but is specifically designed to protect surfaces that require regular maintenance. The Daddi Long Legs anti-bird device is a spider-shaped deterrent with a rotating head from which fine stainless steel wire ‘arms’ protrude. This product is manufactured and distributed by a company in the United States called Bird-B-Gone.
The unit is mounted on a UV protected polycarbonate base and comes in three sizes; 1.25 metre diameter, 1.8 metre diameter and 2.5 metre diameter. Each model will protect a circular area equivalent to the spread of its ‘arms’.
The stainless steel ‘arms’ are constructed from extremely thin wire and as a result move and wave freely in the wind. When a bird attempts to land on the surface protected by the device, its feet will touch the ‘arms’ resulting in the bird feeling unsafe and aborting its landing. The ‘arms’ should extend slightly over the area to be protected (2″ is recommended by one supplier) to ensure that birds cannot perch on the edge of the surface. If more than one unit is installed the ‘arms’ of each unit should just touch each other.
The Daddi Long Legs anti-bird device can be used to protect a wide variety of surfaces including street lights, air conditioning units, grain silos, flat roofs, boats and virtually any other surface. Although the product is relatively expensive compared to industry standard products such as the anti-roosting spike, its main application is intended to be hard to protect areas such as a domed street light housing or the roof of grain silo where conventional products may be less effective. As the Daddi Long Legs anti-bird device requires no maintenance and is simple and quick to install the product will have particular appeal to those wishing to undertake a DIY installation. The product would also be ideal for mounting in areas where access is difficult or expensive.
The Daddi Long Legs anti-bird device is virtually invisible when viewed from a distance mainly due to the extremely thin stainless steel ‘arms’ and the white plastic base and head. When mounted against the skyline the unit is almost impossible to see. The plastic base and head are made from a material called delrin, a frictionless material that allows the base and head to rotate freely. The only disadvantage of delrin is that the material is resistant to glue so an acrylic mounting plate is supplied with each Daddi Long Legs so that it can be screwed to the base of the unit. The acrylic plate is then adhered to the surface to be protected with a strong adhesive. Alternatively the base of the hub can be screwed directly to the surface to be protected with stainless steel screws.
In areas where high maintenance regimes are necessary or where constant human access is required, the Daddi Long Legs anti-bird device is ideal due to the fact that the ‘head’ can be de-mounted from the base unit whilst maintenance takes place. Once maintenance is completed the head is simply re-attached to the base unit. The only other ‘reversible’ product on the market is the anti-roosting spike which can also be removed and replaced with ease when access is required.
The Daddi Long Legs anti-bird device is highly recommended for specialist installations such as pleasure craft in marinas where problems with gulls and pigeons are common and where conventional products are often inappropriate. Several ingenious adaptors are available to fix Daddi Long Legs to commonly-used perching places on boats. A railing mount is available to attach the unit to safety railings around the boat with a quick-release screw so that the unit can be de-mounted quickly and easily. A ‘boat mount’ is also available that allows the unit to be attached to almost any area of a boat with bungee cords or rope – examples of where the adaptor might be used to great effect is on a coiled sail or horizontal mast. Finally, for all areas where the ‘boat mount’ and the railing clamp cannot be used, a ‘sandbag base’ is available. The sandbag base is simply a weighted bag of sand to which the unit can be easily attached.
Another example of where the Daddi Long Legs anti-bird device can be used to protect an area often used by birds but difficult to protect is a flat roof. The roofs of single storey extensions are commonly used by garden birds and pigeons as a vantage point to exploit food provided on bird tables. Flat roofs are also used extensively by seagulls for the purpose of nesting. Most roofs, particularly felt roofs, are difficult to access and damage can be caused by constant human access to clean-up bird excrement. Daddi Long Legs can be adapted for installation on flat roofs and once installed, requires no maintenance. Daddi Long Legs can be installed on a flat roof by placing paving slabs on the roof at required intervals and then attaching the unit to the slab. The unit can be attached to the slab by drilling 3 holes into the slab, inserting a raw plug into each hole and then fixing with the stainless steel screws supplied. The base unit is ready drilled with three holes for the purpose. The units can then be moved as required, whilst still attached to the slabs, to ensure that the required protection and coverage is achieved. Alternatively the head can be detached from the base unit and then re-installed.

Editorial comments:
Daddi Long Legs is a unique and versatile anti-roosting product that has its main application in difficult to protect and difficult to access areas. Its main advantage is that it is simple and easy to install and most installations can be undertaken without the need to instruct a specialist contractor. The product is as appropriate for residential and ‘home’ installations as it is for large-scale commercial applications, although the cost of the unit is always going to be an issue where the protection of large areas is concerned. Daddi Long Legs is also ideal for specialist applications such as boats or ships and can be fitted to virtually any surface.
Daddi Long Legs is a low visibility product and therefore has considerable appeal for those needing to protect an area where aesthetics are an issue. Any bird deterrent or anti-perching device that blends in with the architecture of the building or site concerned is highly sought after but many of the products that fall into this category, such as nylon bird netting, are often prohibitively expensive and can degrade very rapidly. The Daddi Long Legs anti-bird device is ideal for installations against the skyline, such as the roof of a grain silo, where the product is virtually invisible from the ground. The product is also ideal for difficult to protect architectural features due to its low visibility and versatility where installation is concerned. The optional installation products such as the sandbag, railing clamp and boat clamp will allow the product to be installed on to most surfaces with relative ease. Ease of installation also means that the product can be removed quickly and easily should access to the area or surface be required. The only other anti-perching product on the market that offers this degree of versatility is the anti-roosting spike.
Daddi Long Legs is ideal for specialist applications such as the protection of boats in marinas or boatyards. Historically gulls and pigeons have been a constant nuisance for boat owners and those managing marinas and boatyards with the only control options being the use of sonic or noise-related devices. These devices may, in part, be effective against gulls outside the breeding season (distress call-related devices are ineffective during the breeding season) but are completely ineffective against pigeons. Daddi Long Legs, however, is an excellent choice for the protection virtually any area of a boat with the added benefit that the product can be quickly and easily removed when not required and then reinstalled when the boat returns to the marina. The fact that the product is white (as are most boats) and is more or less invisible against the skyline further lends itself to this application.
One of the most difficult areas of any building to protect is a flat roof. Nylon netting is commonly recommended and used for this application by contractors.Nylon netting is expensive, invasive to install, has the potential to trap birds and often degrades quickly requiring regular maintenance. The Daddi Long Legs anti-bird device is quick and easy to install on flat roofs and has the added advantage that once installed the product requires no maintenance. Should access to the roof be required for any reason the ‘head’ can be removed and replaced easily as can the whole unit if necessary, assuming that it has been attached to a paving slab as is recommended for this application.
Daddi Long Legs may be expensive relative to low visibility anti-perching products that achieve the same goal, but the product certainly has validity as a stand-alone device for use in hard to protect areas. If Daddi Long Legs is compared directly with a product such as nylon netting, however, there is no doubt that once installation and maintenance cost associated with the installation of netting are taken into consideration, Daddi Long Legs would be the more cost effective option. If used in conjunction with anti-roosting spikesthe combination of the two products will often be all that is required to comprehensively proof a building, particularly where aesthetics are an issue or where invasive bird exclusion products are forbidden, such as on many grade listed buildings. The benefits and flexibility of the Daddi Long Legs anti-bird device appear to outweigh any disadvantages associated with the initial cost of purchasing the unit.

Bird Proof Bird Gel and
Bird Liquid
OVERVIEW
Repellent Gels & Repellent Liquids are bird prevention products that are designed to prevent birds perching or roosting. Repellent gel is normally used to prevent birds landing on solid external surfaces such as windowsills or architectural features and is applied using a mastic gun (caulking gun). Repellent liquid is a less viscous version of the same product allowing the user to spray or paint the liquid onto larger or more difficult to treat internal areas via a pressurised spraying device. There are numerous brands of both repellent gel and repellent liquid available on the market with most branded gel and liquid products having the same properties and being used and applied in the same way.
Repellent gel is recommended for most types of external application and repellent liquids are more commonly used for internal applications. Both products are relatively easy to apply and virtually any surface where birds perch or roost can be treated with the product. Even trees and shrubs can be sprayed with repellent liquid. Both products are suitable for use with all species of birds making the products extremely versatile. Repellent gel and repellent liquid are both non-poisonous and non-harmful to birds according to the manufacturer, but both products can cause redness and irritation to human skin when contaminated and instructions for use of repellent liquid suggest that the product should not be sprayed directly on to birds. One supplier suggests that the product can irritate human eyes and eyelids can become glued together on contact. This clearly suggests that repellent gel can also glue the eyes of birds together.
Bird Gel on Windowsill
Repellent gel is a transparent sticky substance that feels tacky to touch and which will remain effective for periods ranging from 2 months up to one year. Repellent gel is designed to be effective in normal temperature ranges but will be less effective in temperatures below 0°C and above 40°C. Whilst gel is non-flammable, toxic gasses will form on combustion due to the petroleum content of the product. Repellent gel should always be coated with a sealant compound once installed to ensure that birds do not become ‘glued’ to the substance. It is a legal requirement in the UK to treat gel with a sealant. Repellent gel should only be used with caution on porous or semi-porous surfaces due to the fact that the substance will ‘leech’ into the stone, potentially causing staining. In extreme cases repellent gel can cause staining to masonry that will require the surface to be sand-blasted in order to remove the residue. A sealant compound is available to treat porous surfaces prior to application.
Repellent gel is available in tubes which fit directly into a mastic gun for application. One tube of repellent gel will cover a 10 foot area when provided in a continuous bead. Installation instructions vary dependent on brand, but repellent gel is normally installed as one continuous strip leaving a minimum gap of 1” per 10 foot of product to allow rain to drain from the protected area. For standard installations on narrow surfaces (less than 4” wide) one ½” bead of product will suffice. For installations on wider surfaces (greater than 4” wide but less than 8” wide) a second bead will be required – the two beads should be spaced 2” apart. In both cases the bead nearest the leading edge of the area to be protected should be installed 1” from the leading edge. For surfaces greater than 8” wide multiple beads will be required. Once the repellent gel has been installed a sealant compound must be installed over the gel to ensure thatbirds cannot become trapped.
Spraying Repellent
Liquid
Repellent liquid has a greater coverage than repellent gel and 1 gallon will cover an area of up to 125 square feet. Repellent liquid can be installed by painting on to the surface to be protected (once the surface has been thoroughly cleaned) or it can be sprayed via hand-pumped sprayers, mechanical sprayers or pressure generated sprayers. In the case of hand-pumped or mechanical sprayers a discharge pressure of up to 40-50 p.s.i. is acceptable. For equipment with a generated pressure a discharge pressure of up to 150 p.s.i. can be used. When repellent liquid is used to treat an internal area such as the struts and cross members of a steel-clad warehouse roof, the product should be sprayed in one continuous film over the areas to be protected. More than one application may be required where larger birds are concerned.
One variation on the standard range of repellent gels is a product called ‘Hot Foot’. The bird prevention product is reputed to prevent birds landing by inducing a burning sensation or irritation in the feet of the bird. The manufacturer of the product suggests that this is not the case and that the gel operates in a conventional way by making the target species feel uncomfortable when landing on the product. The UK Government’s Licensing body for pest control products (DEFRA) confirms that the product is not licensed for use in the UK, although a majority of conventional Repellent Gels & Repellent Liquids are licensed for use in the UK.
DEFRA’s view:
The Department of the Environment, Food and Rural Affairs (DEFRA) is the UK’s Government body that oversees the Wildlife and Countryside Act and produces legislation to which the pest control industry must adhere. The following information is taken from a document provided on DEFRA website entitled: ‘Review of international research regarding the effectiveness of auditory bird scaring techniques and potential alternatives’. By J Bishop, H McKay, D Parrott and J Allan.
“Tactile repellents involve the use of sticking substances that prevent birds landing because of their ‘tacky’ feel. They can be applied as clay-based seed coatings, or as pastes and liquids on ledges and other roosting structures to deter settling birds.”
“Tactile repellents to prevent birds landing contain polybutene and may contain other substances to induce a chemical reaction that gives the bird a mild ‘hot foot’ (Transport Canada 1994). They are easy but time consuming to apply as a paste, and although they are not weather resistant, can last up to a year in a sheltered area (Transport Canada 1994). They are known to be effective at preventing pigeons landing and have been used to prevent raptors from landing on antennas, but for smaller birds such as sparrows, they are less effective as they require only a small area for perching and may not come into contact with the repellent (Transport Canada 1994). Such ‘hot foot’ repellents are not licensed for use in the UK.”
Price range:
Bird repellent gel and bird repellent liquid are both available in the UK and one leading supplier of pest control products offers the products at the following prices:

User reviews:
The following user reviews are for repellent gel. No user reviews were available for repellent liquid:
Gary Iori, Manager of Pittsburg Municipal Airport in Pittsburg, Kansas said:
“I spread Bird-Proof gel around one T-hanger with a caulking gun. In a couple of days, the birds were out of there. They left and didn’t come back. I applied it 2 years ago and again this year.”
Barry Schader, owner of Tischler Brothers, a general construction firm, said the following of a branded gel product:
“Immediately upon installation of ‘Bird-Proof’, the birds went away. They won’t inhabit or roost where the gel is applied, and it discourages them completely by making them uncomfortable.”
“’Bird-Proof’ is useful in any area, and I’ve recommended it to others.”
“Birds like to roost along dormers, under eaves and soffits and on ledges. For homeowners this means they are continually washing their sidewalks and cleaning their gutters. ‘Bird-Proof’ virtually ends such repetitive hassles immediately.”
Will Kramer. Maintenance Supervisor for Griffin Corporation in Casa Grande, Arizona, said:
“It was one of the top priorities given to me,” (Griffin’s main building is metal with a trestle-type roof superstructure and many pipes and water lines) “It’s very hot in Arizona, and the birds, especially pigeons, came inside to find shady spots. Pigeons sat on the rafters, roosted all night, and dropped all night. They messed up the entire area where people entered the administrative offices.”
“Before I was Maintenance Supervisor, someone else in the company had tried using high-frequency squawkers to prevent birds landing. The pigeons sat on them. I’m not sure that loud noises are so effective.”
“We tried a pellet gun, but you must be a perfect shot. And the pigeons just fly away momentarily and come back. They’re smart; they recognize a gun.”
“Then an ad for ‘Bird-Proof’ bird repeller in a chemical trade magazine caught my eye. This is probably the best way to do it I thought — a permanent solution. So I ordered a case of 12 cartridges. That was more than a year ago, and we’ve had no pigeon problems since.”
“You don’t need much. We just applied it on the pipes and everywhere the problem pigeons roosted. We used a lift truck with a man cage.”
“We put the gel on and waited. In two or three days, the pigeons were walking around with balls of feathers and debris on their feet. They looked funny. The sticky stuff did the job. The pigeons didn’t bother us anymore. It was 100 percent effective as a deterrent. There were no ill effects from ‘Bird-Proof’, it was just sticky and made roosting uncomfortable for the pigeons.”
Comments from the Manufacturer/Distributor:
One leading distributor of pest control products in the UK said the following of repellent gel:
“For light – medium pressure sites. Prevent birds landing on their normal roosting areas with an application of Bird Repellent Gel, a non-toxic, sticky chemical that makes a surface tacky and uncomfortable to birds. Birds avoid Bird Repellent Gel like humans avoid wet tar. The gel skins but never sets hard, yielding an unstable surface for the birds to land on.”
“Use in any weather, indoors or outdoors, literally anywhere. Water tanks, trees, shrubbery, shipping docks and railroad sidings, yards, parking lots, roof perimeters, air conditioners and more.”
“WARNING: This product may leave a lasting residue on porous surfaces such as unsealed masonary ledges. Always read the label proir to installing and wear suitable protective clothing as advised by the instructions.”
A UK-based pest control company and supplier of repellents said the following of repellent gel:
“In certain applications bird repellent gel represents great value for money since it can normally be installed for a fraction of the cost of the more commercial systems. However, this system is only really effective in low pressure areas and it will probably have to be replaced every few years to remain effective as it breaks down in the environment.”
One US supplier of this branded gel repellent product said the following:
“’Tanglefoot’ paste bird repellent is a clear sticky compound used to prevent pigeons, starlings and sparrows from landing or roosting on most flat surfaces. This non-drying sticky paste adheres to all surfaces. It is registered with the U.S. Environmental Protection Agency for use against pigeons, starlings and sparrows. ‘Tanglefoot’ is generally used on bird resting places, such as window sills, roof ridges, gutters, ornamental coping, stonework and ledges. It can remain effective from 2 months to 2 years depending on the environment. Excessive dust, pollution, bugs and debris can cover the Tanglefoot reducing product effectiveness. To regain control, remove existing paste, clean the surface and reapply the Tanglefoot.”
One US supplier of repellent liquid said the following of a branded repellent liquid product:
“For trees, bushes, shrubbery and most broad surfaces that would make cartridge application impractical, spray on ‘Bird-Proof’ Liquid Spray. Keep birds away from parking facilities, trees, bushes, shrubbery and most broad surface areas with ‘Bird-Proof’.”
“Although it is non-toxic and non-lethal, its “feel” is extremely irritating to roosting birds. ‘Bird-Proof’ protects your property for one year or longer with just one thorough application.”
“In any weather, on almost any outdoor surface, you can protect your property from the annoyance, mess, and continuous clean-up that pest birds bring. It’s the easiest way to bird-proof open or recessed areas and hide-away corners.”
“’Bird-Proof’ is environmentally sound and can be applied with either a power sprayer or a hand sprayer with a discharge pressure of more than 40 psi. One gallon covers up to 120 square feet of surface or an average tree with a five inch diameter trunk.”
The manufacturer of ‘Hot Foot’ repellent gel said the following of the product:
“’Hot Foot’ Repellent Gel is totally different from traditional tactile repellents. Its chemical formula is so different that it carries a worldwide Patent and a two year performance guarantee.”
“’Hot Foot’ works through its sticky nature, NOT by burning or irritation. As birds go to step out of the Gel they experience the feeling that their foot is stuck. This feeling is disliked and the message is quickly communicated to other members of the flock which quickly abandon the treated surface.”
“To achieve this function it is essential that the correct bead depth be applied and maintained on the surface where birds are roosting. This bead depth is achieved by cutting the cartridge nozzle in the appropriate place relative to the size of the bird as explained in this website.”
Editorial comments:
Hot Foot Repellent Gel
Repellent Gels & Repellent Liquids appear to have numerous applications, both internal and external, as well as being effective for use with a vast majority of pest species of birds. The product is simple and quick to install and installation can be carried out by the property owner rather than requiring the services of a specialist contractor. User feedback is very positive and although the product is clearly used extensively in the USA it is not as widely available in the UK. The profile provided by manufacturers and distributors suggest that this product is hard to beat as an all-round anti-perching device.
There are a number of problems inherent with the use of both repellent gel and repellent liquid, particularly in the UK where strict legislation exists in respect of how the product is installed. There is a legal requirement for anyone that uses or installs the product in the UK to treat repellent gel with a protective coating that is designed to ensure that any bird that lands on the product will notbecome trapped or coated in the product. Applying the protective coating is not only time consuming but also adds to the cost of the installation and many pest control contractors fail to treat the gel for these reasons. As a result any bird that lands on the gel is at risk of becoming stuck in the gel, particularly if the product has been installed in an overnight roosting area where the target species will be stationary for 8-10 hours.
Bird Proof
Repellent Gel
The most common problem associated with untreated gel is that birds will land on the product, find that they are unable to move their legs and then start to flap their wings in an effort to free themselves. The wings then become coated in the product and when the bird eventually frees itself and attempts to fly it will plunge to the ground unable to use its wings. Repellent gel can also glue the eyes of birds together (as it can in humans) and therefore the product has thepotential to cause serious injury or death to the target species and any other species that lands on the gel. Even if the product has been installed by a bona fide pest control contractor the legal responsibility for applying untreated gel will lie with the property owner, not the contractor. If a protected species such as a peregrine falcon dies or becomes injured as a result of coming into contact with untreated gel large fines and even imprisonment can result. At the time of researching this product only two leading UK suppliers of repellent gel and liquid (Huck Nets and Network) provided confirmation on their website that there is alegal requirement to treat gel products with a sealant compound.
Another problem inherent with the use of gel as an anti-perching device is the speed at which the product will degrade and become ineffective. In some cases manufacturers and distributors suggest that the lifespan of the product may be as short as 2-months, in others up to a year. Whatever the case, the lifespan cannot be considered to be anything but extremely short relative to industry standard anti-perching products such as the anti-roosting spike. If the product is provided in a dusty or dry area, where the gel becomes coated with dust or sand, the product can be rendered ineffective almost immediately following installation. Any bird exclusion product or anti-perching product that is provided at height, where access is not only difficult but also expensive, must be able to stand the test of time. In most cases, where bird controls are required at height, the cost of access to areas where birds are nesting or perching can actually cost more than the product itself. Therefore, if a product has an effective lifespan of between 2 and 12 months, it cannot be considered to be cost-effective irrespective of where it is installed.
Bird Proof
Repellent Liquid
Both repellent gel and repellent liquid are extremely expensive to buy relative to conventional anti-perching products. One tube of gel costing £7.99 will only cover an area of 10 feet when provided in a continuous bead, with the product requiring re-installation every 2- 12 months. An equivalent meterage of anti-roosting spikeswould cost in the region of £12.60 and the product would not only be significantly more effective as an anti-perching device but would not require replacement for a minimum of 12 to 30 years. Repellent liquid appears to have a greater coverage than repellent gel (up to 125 square feet) but distributors suggest that the product may need re-coating for some of the most commonly controlled birds such as pigeons and gulls. If re-application is required overall coverage from a 3.78 litre (1 gallon) container will be reduced from 125 square feet to 63 square feet. When the cost of a 3.78 litre container (£34.99) is taken into consideration, and the fact that the product may need to be replaced as regularly as every 2-months, repellent liquid is no more cost effective than repellent gel.
Another significant disadvantage of both repellent gel and repellent liquid is that the product may damage the surface upon which it is provided. Gels are renowned for seeping into porous stone and leaving a residual stain which is difficult to remove without using invasive techniques such as sand-blasting. Although there is a primer available to treat stone to ensure that seepage does not take place few contractors ever use it, in the same way that sealant is rarely provided on newly installed gel.
Repellent Gels & Repellent Liquids are simply not cost effective anti-perching product relative to other products on the market. Both products are expensive to buy, require a sealant compound which adds to the cost, have the potential to trap or harm birds, can damage the surface upon which they are installed and require replacement anywhere between 2 and 12 months following installation. Although manufacturers and distributors claim that the product is not harmful to birds or humans, the product clearly has the potential to cause skin and eye irritation to humans (including gluing eyelids together on contact) and if the product is not sealed it can also be potentially fatal to birds.

Post & Wire System
OVERVIEW
The post and wire pigeon wire system is an industry-standard pigeon proofing device that is normally provided on solid flat surfaces to stop birds perching and roosting. Post and wire pigeon wire systems are used exclusively for the pigeon proofing of buildings where larger birds such as pigeons and gulls are causing problems. Post and wire pigeon wire systems used for the control of gulls require different fixings than systems used to exclude pigeons but the principle of both systems is the same. The main benefit of a post and wire pigeon wire system is that the system is virtually invisible when installed at height and viewed from ground level. Post and wire pigeon wire systems are suitable for pigeon proofing where daytime perching problems are the issue, such as ledges overlooking a regular feeding site, but should never be used in areas where birds are nesting or roosting overnight.
Post & Wire System
Post and wire pigeon wire systems can be installed onto virtually any surface that will support the vertical posts but as the integrity of the system is based on tension the foundation for the post must be solid. Post and wire pigeon wire systems are commonly installed on windowsills, ledges, ridge tiles and architectural features such as balustrades and string courses. Where the system is provided on masonry or wood, the vertical posts supporting the system would normally be installed into the surface to be protected by drilling. On surfaces such as lead flashing or bitumen where drilling is not an option, special vertical posts would be installed into a wide plastic base. The base would then be glued to the surface with a high-quality adhesive. The main disadvantage of using this method is that the adhesive must be allowed to ‘cure’ before the system is placed under tension. Curing can take a considerable time, particularly when installed in low temperatures. In temperatures below 5° C curing time can be several days. In temperatures above 5° C the product will need to be left overnight before tensioning the system. Where a post and wire pigeon wire system is considered for a Grade Listed building, permission must be sought from the Listed Buildings Officer before any works are undertaken, particularly invasive works such as drilling.
Post & Wire System
A conventional post and wire pigeon wire system comprises of a series of vertical posts installed onto (or into) the surface to be protected through which a plastic coated stainless steel wire passes at a height of between 110mm-150mm, depending on the target species. The wire is tensioned by springs which are attached to ‘anchor posts’ provided at each end of every 3 metre section. The principle of the system is that when a pigeon attempts to land on the proofed surface its feet will touch the thin steel wires making the bird feel unsafe and the landing will be aborted. The system can be used to pigeon proof ledges and flat surfaces of any dimension by providing multiple rows of the product.
Post & Wire System
A basic system would be provided with an anchor post installed at either end of each 3.0 metre span with intermediate supporting posts (guide posts) provided at intervals of no more than 1.5 metres. If a span is less than 3.0 metres an anchor post would be required at each end of the span. For spans of more than 3.0 metres the system would simply be built up in 3.0 metre sections until the entire surface is protected.
Post & Wire System
A spring is attached to each anchor post and the stainless steel wire is then connected to the spring via a nickel-plated copper crimp (or ferrule) for which a special crimping tool is required. The steel wire is then fed through the intermediate guide post (turned at a 90° angle from the anchor post) and crimped to the next spring, which is in turn hooked onto the next anchor post. Anchor posts would be positioned so that the flats of the eyelets are in line with the steel wire – this adds strength to the installation.
Post & Wire System
When installing a single row of product the ‘leading edge’ vertical post should be a multi-headed post that will allow for a secondary steel wire to be provided halfway down the vertical post. This would normally be provided to ensure that the target species cannot simply land on the leading edge of the surface to be protected and walk underneath the main wire. Where both pigeons and gulls are the target species a taller triple headed post is available. In a conventional installation, where multiple rows are required, the leading edge row would be installed with 110mm posts and the intermediate rows with 150mm posts. Spacing of the rows and posts is critical to ensure total protection is achieved. The following table indicates the rows of product that would recommended based on the depth of the area to be protected:
| Rows of Product Recommended |
Depth of Coverage Required (cm) |
| 1 |
0-5 |
| 2 |
5-12 |
| 3 |
12-20 |
| 4 |
20-28 |

| 6 |
35-43 |
| 7 |
43-51 |
| 8 |
51-58 |
| 9 |
58-66 |
Row spacing is also important when installing multiple rows of product:
- Spacing between intermediate rows of product – no more than 78mm
- Spacing between leading edge row and outer edge of the surface to be protected – no more than 26mm
- Spacing between the final row and the wall (or the rear edge of surface to be protected) – no more than 26mm
Post and wire pigeon wire systems can be installed onto wood, masonry, metal and glass surfaces and in each case a different installation is required:
Masonry:
A 26mm hole would be drilled into which a nylon anchor rivet is installed (25mm for 110mm posts and 38mm for 150mm posts). The main purpose of the anchor rivet is to keep water from entering the drilled hole. The vertical post is then installed into the anchor rivet. Once the vertical post has been seated into the anchor rivet a bead of silicone should be provided at the point where the steel post joins the anchor rivet to ensure water cannot enter the drilled hole. For a vertical application (window reveals, vertical stonework or ends of ledges) split pins can be inserted into the anchor rivet instead of a vertical post.
Wood:
A special ‘nail point’ vertical post would normally be used in woodwork. The ‘nail point’ post is a standard vertical post with a pointed nail-like head which would be hammered into place in the same way that a conventional nail would be hammered into a piece of wood. In order to stop the wood splitting a small guide hole should be drilled prior to inserting the post. The product can also be installed by using a nylon rivet as per a masonry installation. If using a ‘stick-on’ post with a flat plastic base the post can be screwed or nailed into place.
Metal:
For installation into metal a ‘stick-on’ post would be used. The post would be positioned and the holes in the plastic base marked on the metal surface. Small guide holes would then be drilled and self-tapping screws (metal screws) would be screwed into place securing the post in position.
Glass:
Post and wire pigeon wire systems can be installed directly onto glass and for this installation stick-on posts would be used with an appropriate adhesive.
Post & Wire System
Post and wire pigeon wire systems can also be used to pigeon proof the ridge tiles on a roof and for this purpose a special ridge-mounting bracket is required. Two different types of bracket are available depending on what shape ridge tile is to be proofed: a triangular ridge bracket and a half-round ridge bracket. Both brackets come with posts already mounted and installation is undertaken by use of an adhesive or by screwing in place using the mounting holes on the bracket. Steel wire is then passed through the eyes of the posts and attached to springs mounted on the ‘anchor’ brackets at each end of the span. Two sizes of bracket are available depending on the target species: 110mm brackets would be used for the control of pigeons and 150mm brackets for the control of gulls.
Post & Wire System
Post and wire pigeon wire systems can be installed as aDIY installation and the product is available in kit form or as individual parts. Although the system may appear to be relatively simple and straightforward to provide, installation does require more advanced DIY skills as well as an understanding of how the target species will react and respond to the system once installed. It is possible to cause serious damage to the surface upon which the system is installed if installation is undertaken without fully understanding the risks. Even experienced contractors can sometimes cause very considerable damage to a building when installing the product if care is not taken during the installation process. It is therefore essential to follow manufacturer’s instructions to the letter.
DEFRA’s view:
Post & Wire System
The Department of the Environment, Food and Rural Affairs (DEFRA) is the UK’s Government body that oversees the Wildlife and Countryside Act and produces legislation to which the pest control industry must adhere. The following information is taken from a document provided on DEFRA website entitled: ‘Review of international research regarding the effectiveness of auditory bird scaring techniques and potential alternatives’. By J Bishop, H McKay, D Parrott and J Allan.
“Pigeon proofing with a thin wire over the perch, which prevents the bird from landing is probably the simplest method. The wire should be low enough that the bird cannot stand under it, but also high enough to prevent the bird from straddling it (Johnson 2002). If a variety of bird species are to be deterred from the same perch, a series of wires at different heights should help to meet the above criteria for all species. White wires deterred pigeons from perching on stadium ledges (Andelt and Burnham 1993). Up to three lines were placed in front of the ledges and at different heights above the ledges. Short-term success was good.”
“All these designs (anti-perching products) may help to deter perching birds but their success is dependent on all perches being treated to discourage birds from the area.”

Editorial comments:
Post & Wire System
The post and wire pigeon wire system is used extensively for the control of both pigeons and gulls and is considered to be an industry standard pigeon proofing method. The product is not suitable for the control of smaller birds or for use in areas where breeding is taking place and therefore the product is considerably less versatile than other anti-perching products. The main advantage of the post and wire system is that it is a low profile product and as a result, is ideal for use where aesthetics are an issue such as the frontage of a historic building.
Post & Wire System
The post and wire pigeon wire system is relatively complex to install based on the various installation options and also because the product will almost certainly need be installed at height. The product is available in kit form for a more basic DIY installation or, for a more complex DIY or tailor-made installation, the various fixtures and fittings can be sourced individually. Professionally fitted systems can be extremely expensive because installation is labour intensive, particularly where stick-on posts and adhesives are used. In some cases this may require the contractor to stop work for up to 2 days whilst the adhesive is ‘curing’ and then return to finish the installation.
Post & Wire System
The post and wire pigeon wire system is an extremely expensive option relative to many other anti-perching systems and although the product is low profile and virtually invisible from the ground when installed at height, these are probably the only two positive aspects of the system. On narrow surfaces where very light pressure pigeon-related problems are being experienced and where access is simple and easy, the product can be effective and relatively straightforward to install. For more extensive areas, such as long wide spans of parapet where multiple rows of product are required, post and wire pigeon wire systems are prohibitively expensive relative to products such as the anti-roosting spike.
Post & Wire System
The post and wire pigeon wire system is renowned for failing, in some cases only days after installation. This is generally due to poor quality installations. It is common to see a row of upright posts installed on a building with steel wires hanging from them – this is normally because the posts have collapsed inwards and the springs have become detached from the posts as a result. In some cases the copper crimps have not been sufficiently tightened so that when the system has been placed under tension, or when a bird lands in the centre of a span of wire, the wire has become detached from the springs rendering the system ineffective. Either way the result is that the system will have to be repaired or replaced. If the system has been installed at height the cost of access alone can be extremely high with the cost of labour and parts on top. If stick-on posts have been used the system is even more vulnerable to collapse as the contact point on the base of the stick-on pad is extremely small relative to the height of the wire. When a large bird such as a herring gull lands halfway between two stick-on posts it is almost certain that the two vertical posts either side will collapse inwards. Even an adult pigeon can have this effect. Once one section of the system has collapsed the integrity of the whole system is compromised and diminished, with repair or replacement being the only option.
Post & Wire System
Another more serious problem associated with post and wire pigeon wire systems is the potential for damage to the fabric of the building upon which the system is installed. Where a system is provided on masonry, and where posts are installed by drilling and fixing, it is essential that the hole into which the post is seated is filled with silicone once the post has been installed. The reason for this is to stop rainwater building up within the hole. Some contractors fail to backfill holes and the results can be extreme. Once water seeps into the post hole and freezes, the ice will expand and can crack the masonry around it with serious implications. The following examples confirm the dangers inherent in poorly installed post and wire pigeon wire systems:
- In the city of Cambridge a famous university listed building had been experiencing minor pigeon-related problems on the frontage of the building. A national pest control contractor was called in for advice and recommended a post and wire pigeon wire system. The system was installed to narrow ledges and architectural features across the frontage of the building. Soon after the system had been installed, crumbling masonry was found on the busy pavement area below the building. It would appear that the masonry had cracked either because the post holes had been drilled too close to the leading edge of the ledge concerned or because the holes had not been backfilled with silicone and water had frozen and expanded within the holes. Whichever the case, the potential for serious injury to those using the pavement below was considerable and the cost of an invisible masonry repair to a listed building cannot be discounted either.
- In the town of Solihull, West Midlands, a large Council-owned Victorian building in the town centre was pigeon-proofed with an extensive post and wire pigeon wire system to all windowsills and architectural features. The system was recommended by an established pest control contractor. The wide windowsills and architectural features were protected with numerous rows of post and wire pigeon wires. Although the system appeared to have been installed correctly, retaining the aesthetics of the building as a result, the system failed dramatically during a period of sub-zero temperatures. Drilled post holes had not been backfilled with silicone and water had built up within the holes. When the water froze large chunks of masonry cracked and fell to busy pavement areas below. Not only did this represent a serious threat to human life but the damage done to the building was serious and expensive to repair. The system also failed to resolve many of the perching-related problems for which it was first installed.
Post & Wire System
It is clear from these examples that the post and wire pigeon wire system is far more vulnerable to failure than many other anti-perching systems. The system is not only expensive to install when using a specialist contractor but even where a DIY installation is concerned, the cost of raw materials alone can be prohibitive certainly relative to other anti-perching devices. For wide surfaces or for the protection of extensive areas, the post and wire pigeon wire system cannot be considered to be a cost-effective anti-perching product. The potential for damage to the building upon which the system is installed is considerable and the potential for the system to fail due to wires becoming detached or posts collapsing inwards is also a very real concern.
Post & Wire System
In the majority of cases where a post and wire pigeon wire system is considered, a system using anti-roosting spikes would not only offer a comparable low visibility option but the spike-based system would cost considerably less than that of a post and wire pigeon wire system. This is because a standard row of 4-point spikes will protect an area of up to 200mm wide and yet to protect an equivalent area using a post and wire pigeon wire system would require a minimum of 3/4 rows of product. The cost of 30 metres of top quality stainless steel anti-roosting spikes (including adhesive) would be in the region of £179.00 inc. VAT. The cost of protecting the same area with a stick-on post and wire pigeon wire system, using the product in kit form, would be approximately £309 inc. VAT. Installation costs for a post and wire pigeon wire system would also be significantly higher than an equivalent anti-roosting spike system with the spike system lasting in excess of 25 years before requiring replacement.

OVERVIEW
At the time of going to press there is one UK manufacturer who is trying to launch an electronic shock track system into the UK but opinion seems to be divided as to whether or not such systems are legal according to the Wildlfe and Countryisde Act of 1981. Although the system may not cause actual bodily injury the electronic device is quite clearly calculated to frighten the bird and therefore may still contravene the act. We will keep you up to date. It is possible, however, to source these systems directly from the USA. According to suppliers, Electric Shock systems are effective with a wide variety of bird species but in the main, are used for the purposes of pigeon and gull control. Although Electric Shock systems can be used for virtually any application where a solid surface exists, the main application for the product would be for controlling pigeons and gulls on buildings in urban areas.
For those considering an Electric Shock Systems system for use in the UK there must be an understanding that the product may be illegal for use based on information provided on the DEFRA website.
In the document ‘Review of international research regarding the effectiveness of auditory bird scaring techniques and potential alternatives’ Turner (1998) says of Electric Shock systems “…such electrical systems may be illegal in the UK.”
Electric Shock systems for use in the bird control sector are based on electric fence technology where electric fences are used to keep livestock in a restricted area without the need to install a permanent fence. The principle of the Electric Shock Systems system for the purpose of pigeon and gull control is to provide a low voltage Electric Shock Systems to the feet of any bird that lands on the electric ‘track’. Conventional Electric Shock systems consist of two wires, housed within the ‘track’ and running in parallel. One wire carries the current from the active terminal of the power box and the other wire is earthed and connected to the earth terminal of the power box. For the system to operate as intended one or both feet of the bird must make contact with both wires. Research has shown that when track is installed on a ledge to prevent perching the section of track housing the active wire should be installed closest to the leading edge of the ledge.
Flexible Electric
Shock Track
One of the most common reasons for Electric Shock systems to fail is an inadequate supply of power to the track. The average power box will supply up to 9000 volts of current but if the voltage falls below 4500 volts some birds will be able to withstand the shock that they receive. Due to the fact that the power source produces up to 9000 volts of current and most power boxes use a standard 110 volt cable to supply current, inevitable leakage occurs from the charged wire to the earth wire, reducing the effectiveness of the track. This problem can be resolved by using an insulated cable with a resistance of at least 9KV. Another reason for failure is leakage of current through poor connections when joining one piece of track to the next. Some of the older and more basic systems require connectors to allow the track to turn corners and these also contribute to power losses. Debris on the track is also a major factor and accordingly, the system should never be installed beneath trees or shrubs which may drop leaves or branches on the track. Any debris lying on the track may result in the feet of a bird failing to make contact with both live and earth wires.
White Electric
Shock Track
The main advantage of the Electric Shock Systems system is that it is extremely low-profile and is therefore considerably more aesthetically pleasing than many other anti-perching and exclusion products. The average Electric Shock Systems system stands somewhere between 0.25 inches and 0.5 inches high and most systems are commonly available in several colours to blend in with the surface to be protected. The system is powered either by direct current (DC) mains current (AC) or by solar power, or a combination of two of these power sources.
Another advantage of the Electric Shock Systems system is that it can be provided on virtually any area of a building including the roof (tiles and ridge tiles), windowsills, architectural features (such as curved arches and window ‘heads’) and even signage and lighting. The system is versatile in respect of application and with recent developments in the design of these systems they are also relatively easy to install. Earlier systems were time consuming to install and required extensive fixings in order to hold the system in place. Earlier systems were also compromised by a lack of drainage during periods of heavy rain with a build-up of water resulting. Water was unable to drain away as a result of being ‘damned’ by the electric tracks themselves and water ingress problems were common. Newly designed systems allow water to drain away beneath the tracks.
Electric Shock
Track Kit
For the purpose of this review we will concentrate on the Bird-B-Gone ‘Shock Track’ electric bird abatement system as this system is a good example of a standard Electric Shock Systems system. The ‘Shock Track’ system is also widely available throughout the USA via several leading suppliers. The ’Shock Track’ system is available in several colours including grey, stone, black, clear or terracotta and is supplied in rolls of 100 feet. The ‘Shock Track’ system is ultimately flexible with the track bending 360° in any direction negating the need for right-angle connectors, as was the case with earlier systems. The ‘Shock Track’ system consists of a flexible UV protected PVC base (or ‘track’) into which two wires are ‘heat-staked’ into plastic – the electric current will pass through these wires. The ‘Shock Track’ is then laid over the area to be protected and attached to the surface by a series of clips that are glued in place with a strong industrial adhesive or fixed in place with nails, screws or self-tapping screws depending on whether the surface is wood, masonry or metal. Once the ‘Shock Track’ is laid the connection is made to the power source and the product is ready for use.
Electric Shock
Track Chargers
The ‘Shock Track’ system can be powered by mains electricity (AC), solar power or by a battery (DC). If the system is to be powered by mains electricity the power unit must be installed in a weatherproof box to ensure water cannot come into contact with the unit. If a solar charger is used, the solar panel must not be obscured by trees, neighbouring buildings or architectural features to ensure good access to direct sunlight. If the system is powered by mains electricity this option will charge 1000 feet + of track but if using a solar panel the unit will only power up to 500 feet of track. The solar panel will need to be installed so that it is facing north in the southern hemisphere and south in the northern hemisphere in order to receive maximum sunlight. Technical specifications for the various power options are as follows:
‘Shock Track’ Direct Charge System
- Input voltage: 110-120 VAC, 60 Hz, 0.35 amps, 10 watts
- Output voltage: 800 volts (+/-) 20% open circuit voltage, intermittent AC output
‘Shock Track’ Solar Charger
- Input voltage: 4 volt, .02 amp, .08 watt
- Output voltage: 7.5 KV (+/-) 20% open circuit voltage, intermittent DC
‘Shock Track’ DC Charger
The DC power supply required to power ‘Shock Track’ is not currently available through BirdBGone but the supplier has confirmed that the unit is widely available from other sources.
Prior to installation the surface upon which the system is to be mounted must be cleaned thoroughly to remove debris, nesting material and bird droppings – this is particularly important if using an adhesive. The area to be protected must then be mapped out to ensure that the ‘Shock Track’ covers all potential perching surfaces including the ends of ledges. When installing the system on a flat surface the first row of ‘Shock Track’ should be installed as close to the leading-edge of the ledge as possible. Guidelines for spacing rows of ‘Shock Track’ are far from clear with the supplier recommending that rows should be installed with gaps of no more than 3 inches but then offering the following guidelines for spacing:
For a ledge or surface with a vertical wall behind:
- 1”-12” ledges – 1 row of ‘Shock Track’
- 13”-24” ledges – 2 rows of ‘Shock Track’
- 25”-36” ledges – 3 rows of ‘Shock Track’
For double-sided ledges or surfaces (such as a parapet wall) one row of track will need to be provided for each side of the surface and installed as close to the leading edge as possible. Further rows should be installed according to the chart below:
- 1”-4” – 1 row of ‘Shock Track’ on each side
- 4”-15” – 2 rows of ‘Shock Track’ on each side
- 16”-28” – 3 rows of ’Shock Track’ on each side
Once the area has been mapped out and cleaned the mounting clips then need to be installed as close to the leading edge of the surface to be protected as possible. The first row that would be installed would be the leading-edge row and subsequent rows would then follow. The mounting clips should be installed no more than 3 feet apart. The supplier recommends that although an adhesive can be used as the sole means of adhering the ‘Shock Track’ to the surface to be protected, the installation will benefit from the ‘Shock Track’ being fixed in situ as well as being glued.

Shock Track
Once the mounting clips have been installed the ‘Shock Track is ready to be installed. The ‘Shock Track’ in unrolled starting from the furthest point from the power source and then the track is clipped and glued to each mounting clip as well as being glued to the surface to be protected between each mounting clip. Each section of the ‘Shock Track’ must then be joined together and this is achieved by crimping the two exposed wires from each individual section of ‘Shock Track’ with a ‘Shock Track Crimp Connector’. The ‘Shock Track’ is then ready to connect to the power source. The two wires from the ‘Shock Track’ are fitted with a ‘Quick Disconnect Terminal’ which is in turn connected to the power source. The ‘Shock Track’ can then be powered up and is ready for use.
There is much debate surrounding the use of Electric Shock systems and although suppliers suggest that the systems do not inflict pain on the target species this is normally in respect of larger birds such as pigeons and gulls for which the systems were originally designed. Animal protection laws in the USA, where these systems originate, are relatively lax compared to similar legislation in the UK. It is often the case that devices allowed for use in the USA, such asanti-roosting spikes with sharp pointed tips, would be illegal for use in the UK.DEFRA has confirmed that it is the responsibility of the user to ensure that any product used for the purpose of bird control is humane and will not cause pain or inflict suffering on the target species or any other species of bird that may come into contact with the product. DEFRA also confirmed that although there had been a flurry of UK-based enquiries regarding Electric Shock systems 2 to 3 years ago when the systems were being promoted in Europe, there have been no enquiries over the past 2 years.
When researching Electric Shock systems several years ago, the UK-based Pigeon Control Advisory Service International (PiCAS International) had extensive discussions with a leading US manufacturer about the use of Electric Shock systems. At that time it was clear that little research has been undertaken to establish whether Electric Shock systems were harmful to birdsand the company concerned was unable to confirm whether these systems could harm or kill small birds. The response from the company was that they did not think small birds could be harmed or die as a result of coming into contact with the product but they had no evidence to support this view. It is clear that other than in exceptional circumstances, larger birds such as pigeons and gulls are unlikely to experience extreme pain or die as a result of coming into contact with an Electric Shock Systems system but the same cannot be said of small birds. If a bird the size of a blue tit or sparrow landed on an electric track carrying a current strong enough to deter a pigeon or a gull the shock may kill a bird of this size. The question of whether the system is a greater danger to small birds in wet conditions, based on the fact that water is a good conductor of electricity, is another factor that must also be considered.
All wild birds are protected in the UK and any user that installs a shock system which harms or kills wild birds, whether deliberately or otherwise, would be liable for prosecution.
DEFRA’s view:
The Department of the Environment, Food and Rural Affairs (DEFRA) is the UK’s Government body that oversees the Wildlife and Countryside Act and produces legislation to which the pest control industry must adhere. The following information is taken from a document provided on DEFRA website entitled: ‘Review of international research regarding the effectiveness of auditory bird scaring techniques and potential alternatives’. By J Bishop, H McKay, D Parrott and J Allan.
“Electrical systems such as ‘Avi-Away’ consist of a cable running along the area to be protected that is attached to a control unit. When a bird lands on the cable it completes an electrical circuit and receives a mild shock. The manufacturers claim that any distress calls given by the bird help to disperse others (Transport Canada 1994). However, such electrical systems are illegal in the UK (Turner 1998).”
“All these designs (anti-perching products) may help to deter perching birds but their success is dependent on all perches being treated to discourage birds from the area.”
DEFRA has confirmed that it is the responsibility of the user to ensure that any product used for the purpose of bird control is humane and will not cause pain or inflict suffering on the target species or any other species of bird that may come into contact with the product.

Editorial comments:
Electric Shock Track
Electric Shock systems are not currently available from UK suppliers of pest control products and therefore if considering a system of this nature the product would need to be sourced direct from the USA. A number of reputable US-based companies supply these systems and shipping to the UK should present no problem. The cost of shipping would have to be taken into consideration where assessing the cost-effectiveness of the system.
The Electric Shock Systems system is a relatively new product and as such further research and development clearly need to be undertaken to establish whether these systems are safe to use against birds and whether they provide the user with an effective anti-perching system. Issues surrounding the effect of shock systems on small birds must be a concern for those considering the system due to the potential for prosecution should the product kill or cause suffering to any species of bird that comes into contact with the device. DEFRAhas made it clear that any person providing a system of this nature without first establishing that the system is safe for use, both for people and birds, will be held legally responsible if the product contravenes the Wildlife and Countryside Act (section 5) or the Animal Welfare Act 2006. It should also be noted that in the ‘Review of international research regarding the effectiveness of auditory bird scaring techniques and potential alternatives’ on the DEFRAwebsite, Turner (1998) suggests that Electric Shock systems are illegal for use in the UK.
The legality of using an Electric Shock Systems system in the UK is clearly a grey area and anyone considering importing a system would be advised to speak to DEFRA in the first instance.
Stone Electric
Shock Track
One very important aspect of installing a mains-powered Electric Shock Systems system on a commercial property is the need to have the system installed or checked by a qualified electrician. If undertaking a DIY installation on a residential property the installer needs to be in possession of a qualification that allows the person to undertake an electrical installation. In 2005 ‘Part P’ of the Building Regulations was introduced which effects all electrical work carried out in, on or outside a residential dwelling. Part ‘P’ of theBuilding Regulations dictates that any person installing a mains-powered electrical device such as an electrical shock system in or on a residential dwelling must be suitably qualified to do so. In order to undertake an electrical installation of the type required to install a mains-powered Electric Shock Systems system an individual must be in possession of a certificate such as a City and Guilds 2391 or the VRQ Certificate for Domestic Electrical Installers.
Electric Shock systems are expensive relative to conventional anti-perching products such as the anti-roosting spike and their installation is labour-intensive. The ‘Shock Track’ installation guidelines are not consistent with the approach taken when installing conventional anti-roosting products, with spacing of the tracks leaving large areas unprotected. If the ‘Shock Track’ installation guidelines are followed for installing the product on a 12”-wide windowsill only one row of product would be required, leaving up to 10” of the sill unprotected. When it is taken into consideration that the maximum extension of the foot of a feral pigeon is approximately 2.0” – 2.5” (from the furthest extension of the leading front toe to the nail of the rear toe), and based on the fact that both wires of a track need to come into contact with the foot in order to deliver a shock, a sill would require a minimum of 6-rows of track in order to be fully protected. Based on this calculation the volume of track required to comprehensively protect any surface would render the product prohibitively expensive.
Flexible Shock Track
Electric Shock systems require regular maintenance and inspection to ensure that debris does not compromise the track and where the system is powered by DC current (supplied via a battery) regular human interaction will be required to re-charge the battery. There are also inevitable running costs when using mains electricity. All these factors contribute to make the system expensive to install and maintain as well as being extremely expensive to purchase. Shipping to the UK must also be taken into consideration.
Electric Shock systems have found a niche in the pest control marketplace due, in the main, to the fact that the product is low-profile and barely visible even when provided at low level. These systems may be appropriate for the commercial user that is more concerned with aesthetics rather than cost-effectiveness, but for the property owner on a budget the Electric Shock Systems system will hold little appeal.

EFFORTS to clear Leatherhead’s main shopping mall of pesky pigeons have taken off after conservationists began the fowl task of clearing the birds and their mess.
Volunteers from the Wildlife Aid Foundation (WAF) began work to clear the pigeons and put up meshing at the Swan Centre last Thursday to stop the birds from nesting in the building’s alcoves.
The Leatherhead-based wildlife charity said it was brought in by the shopping centre’s management to make sure the unwanted guests were removed “as humanely as possible”.
The charity’s founder and chief executive Simon Cowell said it was common practice for building managers to remove pigeons by shooting or poisoning the birds.
He said: “There is no good or bad time to remove pigeons as they nest all year round, but it is better that they are removed than killed and we will do so in a completely humane and sensitive manner.
“The cleaning was started as was the meshing but sadly the job was much bigger than we first anticipated so we will be working with the Swan Centre to finish up over the coming days.”
He said shopping centre managers will now finish installing the netting and charity staff will then return and remove small parts of the netting to complete the clear-out, before replacing it.
Mr Cowell added that he hoped the method for dealing with the Swan Centre’s pigeons could become the model for how wildlife intrusions are dealt with in shopping malls and public spaces in Surrey.
“We got one baby out and it was a hell of a mess up there,” he said. “It was really nice that they wanted and asked for us to deal with it as opposed to the much nastier way.
“The Swan Centre deserves praise because to see big companies taking the less practical but more humane route is rare and it shows the community cares about its wildlife.
“Pigeons might not be the most popular of wildlife but they are just as important as any other and deserve as much of our attention as anything else.
“It’s a shame that when these shopping centres are built thought isn’t given to the wildlife. If they were built properly in the first place we would have no need for meshing or the spikes.”
