The uric acid in the pigeon’s feces is highly corrosive and a flock of pigeons can cut a roof life in half. They frequently cause extensive damage to air conditioning units and other rooftop machinery. There are also other economic costs associated with pigeon infestations such as slip and fall liability and projection of unclean, dirty company image. Besides physical damage, the bacteria, fungal agents and ectoparasites found in pigeon droppings represent a serious health risk. Handling a pigeon infestation most often requires a combination of products, anti-roosting devices, and sanitation methods.
Pigeons should not be fed because the feeding of pigeons attracts rats and mice, which take any uneaten food. Pigeon nests, droppings and dead carcasses provide a home for a wide variety of insects. These infestations can spread into buildings causing nuisance, damage and skin irritation. Pigeons carry a number of potentially infectious diseases such as Salmonellosis, Tuberculosis and Ornithosis. Contamination of food by pigeon droppings or by the birds themselves can transmit these diseases to humans.
Human food lacks the necessary nutrients the birds require for good health. Feeding attracts pigeons into an area that is potentially hazardous to them – resulting in damage to wings and feet. Feeding results in all year round breeding which causes overcrowding in roosting sites, allowing disease to spread quickly within the flock. Pigeons are wild birds, capable of searching out their own natural food supply. Regular feeding by humans destroys their ability to fend for themselves and makes them dependent on humans.
