My BIL had a house in TN close to Dollys place and the squirrels were thick. They came on the deck and would chew on the window frames and wooden shutters. I repaired the windows 2 times but the little bastards just kept coming back no matter what we tried. I finally got some of this stuff from Tractor Supply as a last resort and it worked. Sprayed the deck and around the windows and they quit chewing on the windows. They have it in spray cans, gallon jugs, and squirt bottles online.
