I had 5 chipmunks move in over the summer, they wrecked my siding and all the insulation..I spent 2 days fixing it and then they did it again next day..same spot. I bought a LIVE trap and trapped all five in a few hours..I held deportation proceedings, found they all qualified and moved them 5 miles to a nice new home (My Congressman's yard)...haven't seen em since..A buddy of mine had a critter chew through his PS hose. PS fluid spilled over his exhaust and caused an under engine fire when he drove the car. Fire Dept showed up and finished wrecking his car, of course, in the process of putting out the fire. Pesky critters...
