I have a deck in the back that is all Trex except for the uprights which are cedar. The resident squirrel has decided the cedar boards are a perfect place to sharpen his teeth and there are now several places where he has gnawed on the deck. I could take him out with a pellet gun, but I really don't want to kill him. I just want to discourage him from chewing on my deck. I kind of enjoy watching the little bugger. Anybody have any non lethal advice for getting him to stop chewing on the deck?
