It is very hard to keep pigeons out of your home. You can’t blame them much of course, they were taken from their rocky cliff habitat in the 1600s however pigeons still remember living in rock and your home, specifically the ledges and crevices remind them of their old nesting places. Deterring pigeons is difficult however you have the option of natural or “professional” pigeon deterrents. If you go natural, you have to pick pigeon deterrents that do not influence or change the environment much such as scare tactics using hawk like stuff toys, silhouettes, eyes and sparkling objects. Professional pigeon deterrents however cause some environmental impact such as pigeon gels that leave behind a chemical stickiness, or the sound pollution done by ultrasonic deterrents. Whatever you choose, make sure you are driving away pigeons and not yourself. If it can’t be helped, combining both natural and professional pigeon deterrents can actually increase the effectivity of both.
