The simple truth is the danger varies depending on the specific infestation. However, if you have a pigeon infestation of any size on your home or property, there is a real risk of contracting an illness from their droppings. The safe bet is to deal with your pigeon infestation as soon as possible to remove any risk of illness.
Pigeons can contract and carry many diseases and parasites which do end up in their droppings. When pigeons find a place on your roof or property to call home, they will quickly create a large mess of their own poop.
Typically at least one of two things are going to eventually happen with pigeons living on your property:
1. Pigeons will poop on your roof and mother nature will make sure that waste ends up on the ground, or in your bushes, trees, and plants. This has the danger of possibly getting tracked into your home by you, your family and even pets. This will cause any disease or even parasites in those droppings to end up right in your home.
2. The pigeons will find a comfortable place to nest and usually will just poop in one place. Those droppings will pile up on your roof or a ledge and will cause direct property damage. Droppings are very acidic and can destroy roofing materials and even damage solar panels. If you get a roof leak, rainwater can soak the droppings causing even more property damage. That tainted water will bring everything in their droppings right into your attic and anywhere the leak travels.
Disease or not, I think can we agree that having a bunch of bird poop on your property is just plain gross!
