Feral pigeons foul buildings, creating unwanted “stained glass” windows and “decorated” architecture. All sorts of pests may migrate from their nests into buildings.

Birds such as Pigeons carry a variety of diseases such as Ornithosis, Listeria and E-coli that can be transmitted to man not only from the droppings but also the birds themselves. When dry, pigeon droppings can become airborne in small particles, which can lead to respiratory complaints such as psittacosis.

Closely linked to Pigeon activity such as nesting are parasites such as mites, ticks, fleas and beetles. So if you have a current or past problem with birds and have done nothing, you may find you’ll suffer from a parasite infestation too.
