there are lots of live traps out there that you can buy. i wouldn't get fancy, just pick one up from a local store (Gander Mtn. if theres one by you is good). then set it out where the rabbits stop to eat or by their den. put some carrots, lettuce, or other bait in it and your ready to go. i've caught tons of squirrels, chipmunks, and rabbits using the simpilest of traps.

good luck.
