Try living in a wood house with giant (

The entire house literally shakes when they hit it. When I was out of town for a while, one left two 2 inch diameter and 2 inch deep holes in the front of the house. And it's illegal to shoot the little shits.
Apparently they are afraid of snakes. A neighbor of mine went and bought about 30 plastic snakes from Walmart and threw them on her roof. She pretty much forgot they were there until another neighbor called her to inform her she might want to check on her "snake problem" ;)
