There is a humane trap that you can purchase that will allow you to catch the critter and then safely haul it out in the country and turn loose. These can be purchased at Tractor Supply or Farm Supply stores. You place bate such as carrots, apples, etc. in the cage and when the groundhog enter to get a free meal, he trips a spring that closes the back door and he is trapped. Just be aware that other critters (skunks, possoms, rabbits, etc) sometimes are caught as well. It is a perfectly safe and harmless for the animal and you. It causes not ill effects to the animal.
