Pigeons can carry a number of different diseases ranging from salmonellosis, tuberculosis and ornithosis. While there is debate in the scientific community as to whether or not pigeons can directly pass these diseases to humans the potential risk cannot be ignored.
Pigeons, aside from their threat to humans and domestic animals through disease, their droppings, nesting materials and dead carcasses can cause mite and insect infestations which create further hazards for humans and domestic pets.
