Bird-OFF Clear Gel is a bio repellent gel created as an efficient and economical means of deterring pest birds. Birds have a natural distaste for sticky things, making Bird-OFF Clear Gel ideal for any surfaces birds may congregate or roost on, including pipes, HVAC units, conduits, I-beams and ledges. The gel is heat-resistant, non-corrosive and applied utilizing a caulking gun. Once in contact with Bird–OFF Clear Gel, birds are presented with a smell and texture they don’t like and are then trained not to touch the gel and not to return to the area. Upon contact with the gel, birds are still able to fly and walk. The gel does not trap birds on the treated surface and can be easily removed using mineral spirits, a solvent available at most hardware stores.
