Are squirrels stealing all your birdseed? Do they keep the birds away - and make a big mess? Keep squirrels out of your hanging bird feeder easily, safely and harmlessly with SquirrelStop! When a squirrel climbs on your feeder, the SquirrelStop senses the weight and activates its motor, spinning the feeder and causing the squirrel to jump off. Squirrels learn to leave your feeder alone - and birds can enjoy their food undisturbed.
