Re: Squirrels destroying my Cedar - Help I have a small-scale version of your problem with a sweet gum. I used to shoot them, but then a pair of red-shouldered hawks moved in across the street. Over three years they fledged 7 young, and they exterminated most of the squirrels and chipmunks. They are just now coming back after the departure of the hawks. We don't have trouble with ash trees - they are almost all gone, and the city has several crews working full-time to remove what's left.
Are there other trees suitable for squirrels besides the ash? Are you treating it? If both answers are no, then get rid of the ash.
