If I had my way I would use a punt gun to clear entire colonies.

They gnawed through my soffit to enter the attic where they pooped, pissed, and fought at all hours. And chewed the evaporative cooler wiring. I patched their hole and they gnawed through my patch. I patched their hole with aluminum and they gnawed an entirely new hole. They eat my tomatoes and squash. I’m patient or stupid. They gnawed through the ceiling and into a pantry. More patching. One day I come home and my dog has a squirrel “treed” on top of the fridge. I trapped a few and relocated them. I suspected I kept trapping the same male squirrel but they all look alike…

Next time I caught one, I spray painted his tail, and took him to my workplace for relocation. This is 4 miles as the crow files and lots of busy roads. Bastard was back within a day.
