Transparent Bird Gel is a sticky repellent gel used to keep birds off of horizontal surfaces. Birds can't stand the sticky sensation on their feet and will move on to a more comfortable spot. Transparent Bird Gel is a low profile means of keeping birds off of ledges, rooflines, beams, signs and other places where pest birds have become a nuisance. Transparent Bird Gel comes in a standard 10 oz. caulking tube. Each tube of bird gel will treat an area approximately 10' long by 3” wide, and will last up to six months outdoors.
