Sometimes it seems like the war between humans and squirrels has no end. You've tried everything - reflective surfaces, corncobs, repellent - but nothing works. Sometimes, though, it's the simplest solutions that work best. This straightforward conical baffler from Woodlink is more than enough to keep those pesky squirrels out of your birdfeeders, and it's very easy to install. Simply use the included coupler to attach the baffler to your pole. (It is compatible with 1/2"- to 1 3/8"-diameter poles.) This polyester-textured, powder-coated steel baffler is also highly weather-resistant and impervious to sharp teeth. Dimensions: 14" diameter x 5 1/4" high.
