ive got squirrels, and they keep on hiding mushrooms all around the hitch area of my 5th wheel camper. ive tossed the mushrooms, but the squirrels just bring them back. i already tried the simple box, stick, string & bait, but that didn't work. the squirrels were too smart for that. i dont want to resort to killing the squirrels, and detering them didn't work. can someone help me build a trap so i can relocate these little buggers?
