Feral pigeons foul buildings, creating unwanted “stained glass” windows and “decorated” architecture. All sorts of pests may migrate from their nests into buildings. Originally descended from the wild Rock Dove, a cliff-face dweller, these birds find the next best thing is a block of flats, a bit of Victorian Gothic architecture or a railway arch.
In the absence of natural predators, birds which fall sick survive to infect healthy ones with ornithosis and other diseases, some of which can be transmissible to man. Their accumulated droppings are also sources of disease.
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.
Pigeon droppings are acidic and can corrode/erode metals, stonework and brickwork. Nesting materials birds use can block chimneys, flues and guttering, causing possible issues with carbon monoxide and damage to buildings as water overflows from blocked gutters.
Buildings covered in fouling looks unpleasant can smell, and projects a poor image of business, potentially ruining an organisation’s reputation. If customers spot evidence of a heavy Pigeon infestation on premises, they may not want to do business with you.
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.
