My wife uses her "Kill Bucket" she is maniacal about the damn things. Take a 5 gal bucket, fill half to two-thirds with water, now float sunflower seeds covering the whole surface, take a small boar 3-4 feet long and 2 or so inches wide and lean it against the bucket making a ramp. Now make a trail of seeds up the ramp into the bucket. Voila! Kill Bucket. The critter walks up the ramp following the trail of seeds and falls into the bucket, no more critter.
