It’s a known fact that most people hate pigeons. Rightfully so. These pests are a major nuisance in places like London and other large cities. But did you know that pigeon poo is actually highly corrosive? Their dropping are the cause of some major damage to buildings.
Pigeons also cause damage to roofs. This mostly happens through nest building. Pigeons build nests and these can end up in gutters. This means that the guttering no longer functions properly and can cause them to flood. These nests may also block air vents and chimneys. But as much damage as this causes, their poo is often an even worse problem. In this post, our experts for pest control in London explain the simple reason why…
Why pigeon poo can damage buildings
What very few people know is exactly how harmful pigeon poo is. The reason for its corrosive properties is that it contains uric acid. This is a strong acid which can eat through brick and stone. Not only that, it can also eat through limestone and sandstone.

Another reason you need to deal with pigeons is that the damage from pigeon poo doesn’t stop once the poo is cleaned off. It penetrates deeply into brick and stone and continues to cause damage. This also damages roofs and can eventually lead to leaks. What’s more, it can eat through plastic and other materials too.
Yet another issue with pigeon faeces is that it eats through metal. This means it can damage a large variety of items on roofs. The most important of these are things like air conditioners. Pigeons love nesting on this equipment, which makes it particularly vulnerable.
Also watch out if you have supplies, machinery, or cars in your yard. Over time, pigeons will cause costly damage to this machinery. Sensitive electronic equipment, like aerials, is also at risk.
Pigeon poo is hazardous in more ways than one
What you should also note is that pigeon mess is a health hazard. It’s filled with bacteria and all sorts of diseases. So be careful when cleaning up after pigeons.

This is why it’s so important that you get rid of these pests entirely. Professional London pigeon controllers have specialist knowledge, techniques and tools to do the job safely and effectively. Do not let pigeons nest on your roof, otherwise you’ll end up with damage that costs thousands to repair.
One of the best ways to prevent pigeons is with bird spikes. These can be placed along the edge of your roof, and also where the birds roost. What also helps is bird netting. This can also be placed where birds congregate. Just be sure to then call in pest control experts. While this may carry a moderate cost, it’s usually far cheaper than repairing your building or replacing your roof.
