Pigeon droppings deface many roofs, monuments, and public spaces. The uric acid (white material) in their droppings is not just unsightly; it can damage the finish on buildings, automobiles, etc. Droppings also contain dangerous fungi and bacteria that are potentially harmful to humans. Some of the diseases they can cause include Histoplasmosis, Cryptococcosis, Psittacosis, and St. Louis Encephalitis.[1] When birds occupy warehouses and defecate on stored goods, this creates an expensive problem for the warehouse management when their customers (retailers) refuse to accept contaminated goods. Pigeons are not protected by federal law; however, you should check your state’s guidelines concerning their protection status and which methods of bird control are allowed before taking action against them. This article provides different methods for you to consider using, depending on your particular context.
