BirdProof is a tacky and non-toxic bird roost aversion solution. Use it on window ledges, rafter beams, signage, displays, and other outdoor surfaces commonly used as roosting areas by nuisance birds. The gel does not harm birds, rather it simply makes bird repellent gel treated surfaces uncomfortable to remain on, intimidating to land on, and uninviting all together. *USE AS DIRECTED.
Birds will typically avoid landing on bird repellent gel just from spotting it. When birds do land they will discover that the surface treated is sticky and uncomfortable remain roosted on. Pigeons and other nuisance birds will remember that the roosting area is inadequate and avoid the gel treated area all together over time.
