Glue traps work great they have them for rats bate the traps with peanut butter but use rubber gloves if they smell your cent on them they will not go on them .
I prefer snap traps for rats and mice. You can use glue as others have mentioned, but it's kind of a gruesome death. The snap traps mean nearly instantaneous death if you set them up correctly.
