The pigeon is a privileged bird with no predator in the urban environment. The presence of pigeons leads to important dirtiness, degradation and the proliferation of certain diseases in buildings. Their elimination is not desirable and in any case impossible. The corrosive droppings eat away at the stone, zinc or copper gutters, paint, and attack the materials in depth.

Current treatments
The installation of stainless steel spikes to prevent pigeons from landing on the areas to be protected. The installation of a net in a courtyard or an inaccessible part. Capture by baiting and trapping in nets or in specially adapted cages. Installation of electrical systems on ledges and roofs.
