Stop squirrels stealing your precious birdfood. The Squirrel Buster lets birds feed freely while denying squirrels. Safe and humane, it’s fantastically effective at denying squirrels a free meal. When a squirrel climbs onto the feeder, its weight automatically shuts off the feeder ports, preventing access to seed. The Squirrel Buster’s patented mechanism adjusts easily to shut out larger birds like pigeons. The patented Seed Tube Ventilation System lets fresh air enter. Hot, humid air escapes at the top, keeping seed cool, fresh and appealing to birds. There’s a generous choice of perching and clinging options, making The Squirrel Buster popular with a wide range of different garden bird species. The feeder’s tough new chew-proof design also shrugs off the worst of the weather. Perfect for any size of garden, The Squirrel Buster is ideal for use with seeds and blends. For extra peace of mind the feeder is backed by a 2-year guarantee. With over 1.5 million Squirrel Busters sold worldwide, there’s no better way to keep squirrels locked out of a free meal.
