I had squirrels problem. Those little suckers can chew just about anything and go anywhere.One day I was getting a glass in the cup boards and found all this saw dust."WTF" I looked up and see a huge gapping hole above. This was a 2.5 story house.
The next summer a 8ft? wood panel fell off the roof with mounds of insulation. Those squirrels torn up the roof for insulation during the cold season.
It was time to sell the cursed house.
