Shark Teeth work on the principle of abstinence. If they can't touch it, climb it, bump it or lick it, they can't tear it up, knock it over, eat up your feed, or waste it! Apply steel Shark Teeth to feeder legs to create a barrier that deters critters. Line the inside of feeder legs to keep Hogs from rubbing or bumping them. Line the outside of the legs to prevent Raccoons from climbing, and pigs and livestock from pushing and bumping your feeder. For best results apply 2 strips per leg. Corner the 2 strips to keep raccoons from bypassing Shark Teeth! Cut 6 strips and mount to the top and sides of your control/timer box. Install strips on your feeder lid to deter raccoons and large birds from roosting or defecating on top of it. Shark Teeth have many uses. Easily form to fit round legs as well as square.
