with all seriousness practice aiming skills rent BB gun and shoot them also make sure if you have kids not to let them see this, or a better way to solve this would be to get a hose and re-enact the seen from "Caddyshack"; good luck have a nice hunting.
Traps don't work, my kids and I shoot them and dig them up. They destroy our yard and garden. Killed 3 last week and now there's a new one in the front yard, saw the tunnels an hour ago. GRRRR !! Hate the little boogers
