Pigeons are highly territorial birds which feed and roost in well defined areas. They have a life span of 10 to 20 years and reach maturity after 2 to 3 years and keep propagating until they are 10 years old. Their diet is varied and hence they are well suited to living in cities and similar built areas.

Pigeon flocks occupy a defined territory and in each flock there are several breeding pairs and dominant birds. The propagation of pigeons is high. Young birds will leave the nest after approximately 40 days. Eggs are laid up to 8 times a year, 2 at a time, so 16 birds are potentially hatched per annum to a single breeding pair.

The Feral Pigeon is the only bird in the world that will make nests using its own droppings. These droppings, when dry, harbour over 40 known diseases including Salmonellosis, Cryptococcosis, Histoplasmosis and Ornithosis, the latter two causing blindness and even death.

Accumulating and decaying bird droppings create offensive odours and will attract flies and other disease carrying insects. Droppings are also highly coorosive, not only to metal, but concrete as well.

On-going cleaning of bird infestation sites are a drain on any house-keeping budget. Droppings onto goods stored in infested areas can make the products unsaleable.

Many different methods have been contemplated or tried in an effort to get rid of infesting pigeons, but most have drawn a blank as to how to tackle the problem.
