When installing Optical Gel™ discs, we begin by thoroughly cleaning the surface to ensure proper adhesion and maximum effectiveness. The discs are then placed at regular intervals across the treated area — on ledges, signs, beams, rooftops, and any other surface where birds are landing or roosting — and secured using silicone adhesive, or zip ties depending on the surface type. Birds perceive the gel inside the discs as fire or smoke, triggering their natural instinct to avoid the area entirely. The discs are low-profile, discreet, and nearly invisible from a distance, making them an ideal solution for properties where aesthetics are a concern. Effective against all species of birds, Optical Gel™ discs are completely humane, require minimal maintenance, and remain effective for up to two to four years before reapplication is needed — making them one of the most cost-effective and versatile bird mitigation solutions we offer.
