I live in the mountains and have all sorts of interesting stuff, lots of bears during the summer months, coyotes, Mt. lions and wolves the rest of the year, but the bane of my existence, is the miserable pack rats, they get into everything. The best remedy I have found is a medium sized live trap baited with peanut butter.
The flaw in that solution is that mice like peanut butter too. I had a number of instances when the trap was sprung, the bait gone and there was nothing in the trap. I put a trail camera on the trap and it was the mice, they got the bait, sprung the trap and escaped through the mesh. Now I set several mouse traps around the live trap.
