Pigeons will roost on homes and businesses creating health hazards and costly cleaning bills with their droppings that contain many different types of diseases that are able to be transmitted to humans.
In addition to the disease risk involved in having large numbers of pigeons and other bird pests around your home, bird droppings that come in contact with your home or car’s painted surface and allowed to dry will warp the paint slightly. In cases where this happens frequently and in large amounts, it may become very noticeable.

One type of fungi that is unique to bird and bat droppings is the fungus that causes histoplasmosis, a serious disease that humans can contract after being exposed to the spores.
