Birds have long been a fascinating creature to humans. Their unique colors and songs have people bird watching around the globe. However, although birds are beautiful and beneficial creatures, they can also be harmful to humans, especially when they invade our homes. Birds are known to carry more than 60 diseases in their bodies and droppings, most of which are airborne and easily transferable to humans. In fact, humans can contract these diseases just by being near their droppings, making birds especially worrisome when they nest in or around your home. In order to help you better understand the danger of having birds nest near your home, I have compiled a short list of the diseases they carry, as well as how you can prevent them from entering your home.
