Motion activated sprinkler works for cats, and deer. If the mice are large enought to set off the sprinkler it might work.

My dog takes care of any rodents, unfortunately, he doesn't know where the line between rodents and wildlife/ or other's pets lies, as long as it sets foot on our land, to him it's game on!
