A pigeon infestation is often the cause of frequent problems. Their nesting habits can cause damage to buildings and their droppings can spread disease. Birds can be harmful to your business. Due to the presence of pigeons, it may be necessary to clean your site, repair buildings and equipment, or replace raw materials and finished products.

What bird species are considered “harmful”?


The laws of most countries protect birds. This is also the case in Belgium. Birds can only be disturbed under certain circumstances or during certain seasons. Before qualifying a bird as a pest, it is necessary to first identify the bird. Before taking any action, check what kind of bird it is. Do not hesitate to consult your pest control professional.

Problems caused by pigeons


Pigeons can cause many problems, but what are the most important? We list seven problems.

1.Pollution or deterioration

Avoid the accumulation of droppings. Dirty and paved surfaces can cause employees and citizens to slip or fall. Pigeons also pollute vehicles parked nearby, which can damage raw materials and finished products, resulting in financial loss.

2.Physical damage

In addition to pollution, a pigeon can also cause physical damage. The biggest birds even move the tiles! In addition, the droppings of pigeons affect stone, metal, paints and other building materials. If the pigeons have access to the attic, they risk damaging the insulation, which leads to repair costs.

3. Spread of diseases

Pigeon droppings can contain different types of bacteria, viruses and parasites. These viruses can contaminate food, surfaces and products. Not only objects can be contaminated, but also people! The pathogens in these droppings may contain salmonella, E. coli bacteria and histoplasmosis. Avoid bird droppings! Read here how to hunt pigeons.

4. Spread of insects

Birds carry ticks, fleas, lice and mites. A real paradise for many beetles, mites, flies and mites! They feed on nest waste, then contaminate the nests and spread through stored products. Think of insects such as variegated carpet beetle, fur moss, leaf beetle, clothing moth and house dust mites.

5.Blocked drainage systems and water damage

Nests blocking gutters and drains can cause roof flooding. This is to be avoided, because these floods are an ideal breeding ground for flying insects and biting insects. In addition, flooding can cause internal leaks, wood rot, corrode metals, damage plaster and cause other damage to wall coverings and floors.

6.Infestation of food stocks

The companies that store cereals and flour are a real pigeon paradise. As a food business, it’s best to make sure the building is well protected from birds. What should you watch out for? Birds can access grain elevators and stores through doors and ventilation points on damaged roofs. Make sure to protect or repair these accesses! Nobody wants to receive packaged products pierced by birds or covered in their droppings.

7.Aggressive behavior of birds

Some birds behave aggressively during breeding periods. Some birds, such as seagulls, can therefore attack people who are close to their nests. Seagulls in particular want to protect their young at all costs. This becomes a major problem if the birds can build their nests without being disturbed and the number of nests on the buildings continues to grow.

What are the signs of a pigeon infestation?
It is important to detect signs of an infestation as early as possible in order to limit costs.

The most common bird infestations are:

  • Installation of pigeons: on roofs, cornices, cables and cabling
  • Droppings: on roofs, cornices, paved surfaces, vehicles and products
  • Pigeon nests: on roofs, cornices, gutters, attics, beams
  • Debris of nests and feathers: debris distributed on your site, gutters and evacuation systems blocked, wet walls and ceilings due to water penetration
  • Damaged stock: caused by bird droppings and packaging pierced by birds
