Pigeons are a common sight in cities around the world, and London is no exception. While these birds may seem harmless at first glance, they can actually cause a number of problems if their populations are not properly controlled.

It is important to control pigeons in London because pigeons can carry a number of diseases that can be transmitted to humans, including salmonella, histoplasmosis, and cryptococcosis. These diseases can be contracted through contact with pigeon droppings, which can contain high levels of bacteria and fungi.

Pigeons can also carry parasites, such as mites and ticks, which can also transmit diseases to humans.

Pigeons can cause damage to buildings. They are known to build nests on ledges, roofs, and other areas of buildings. Over time, the weight of the nests and the droppings they produce can cause structural damage to the building. Pigeons can also damage building materials, such as brick and stone, by pecking at them.

Pigeons can be a nuisance to people living and working in the city. They can be loud and aggressive, especially when they are nesting or caring for their young. Pigeon droppings can also be unsightly and unpleasant to clean up.

Pigeons can pose a hazard to planes and other vehicles by flying into their paths or building nests in areas where they are not supposed to. In addition, pigeon droppings can make roads and sidewalks slippery, which can be dangerous for pedestrians and drivers.
