...the other day. I was workinig in my shop when I heard what I thought was a bird on the metal roof. Looking up, I saw a squirrel scampering down to a perlin with a mouth full of insulation. Went back to the house and brought out my Benjamin/Sheridan .20 cal and a tin of pellets, chambered one and pumped it four times (didn't want a through shot to put a hole in the metal siding) and waited. Sure enough, here he comes again with another mouth full of insulation. I pick up the rifle...he sees me and stops on the perlin. One less pest! And no hole in the siding either. Perfect! The advantage of a pumper...pick your power.
