Stop squirrels in their tracks - and that’s guaranteedThe original Squirrel buster® that started it all, with almost double the capacity of Squirrel Buster® Mini. Four dual-level feeding ports provide excellent access for perching birds. Squirrel Buster® uses patented, proven technology to stop squirrels in their tracks while allowing visiting birds to feed freely. The weight of raiding squirrels automatically blocks access to feeder ports. Offering quite exceptional value for money and is supported by a cast-iron. For use with seeds and blends.
