Squirrel-Proof and Harmless: Squirrels have long been a costly source of frustration for those of us who want to feed and nurture bird life. For years, people have watched squirrels destroy feeders, outwit every squirrel-proof contraption and gorge themselves on food intended for birds. The Squirrel-Off Solar Powered Feeder is the ultimate high-tech, yet harmless defense. Winner of three "Best New Product" awards, including the Birding Industry Best New Product award in 1998, the Squirrel-Off Solar Powered Feeder is the only attractive and, we believe, completely squirrel-proof feeder available today. Dependable and Effective: The feeder uses a mild, yet harmless, electric charge that keeps squirrels and other pests off of your feeder. Birds are not at all affected by the electronics. The squirrels are forced to feed off of seeds birds spill on the ground. Birds will eat from the feeder, squirrels will forage off the ground. Squirrel-Off creates a habitat of harmony in any Yard!
