This is what i have used around the house. In last few months caught a dozen coons couple groundhog, possums. I have used variety of bait. Mostly some cat food
A 220 is the number one ground hog machine.. but.. I'd probably shy away from setting one close to the public.. to many ankle biters around.. I have caught a train load in a live trap with cantaloupe for bait.. cut a few pieces about the size of a walnut and lead him in there.. they are pretty easy to catch
