Private homeowners and landlords are increasingly faced with a problematic situation.
Pigeons and other so-called harmful birds become a real plague. Bird excrement ruins facades in the long run due to the nitric acid contained and leads to corrosion of roofs. Nesting materials regularly clog gutters and drains. Window sills, sidewalks, shutters, etc. are also often heavily soiled. In addition, tenants, residents, passers-by and customers feel harassed. The economic consequences: Annual damage to existing buildings running into millions.
Pigeons have learned to survive in almost any environment, plundering our food waste and requiring only minimal shelter for nest building. The longer the birds nest or hibernate in unwanted areas, the harder it is to get rid of them.
