My dad once enjoyed having squirrels around his place. They eventually chewed their way into his attic and caused $13,000 worth of damage! And, my dad did most of the work himself. This happened back in 1989. I wonder what it would cost today, especially if you had to pay someone to do the work?
He bought a really nice pellet rifle (I think a Gamo). He got very good with that thing. He could peel 'em off a branch even when they gave him only a peeking-over-the limb shot. My 4 boys got to be great iron-sight rifle shots as a result of helping keep Paw Paw's squirrels under control.
I would be much more concerned if predators were hanging around my place. Would I allow squirrels to get into my run or coop? No!
