to keep them out is certainly preferred, ...... but if you already have them inside, a mouse trap baited with peanut butter can not be beat, .... mice can be so skillful and lite of touch, they can get the bait and not set off the trap,..... so smear a small dab of the pb under the little food lever, that way as they maneuver and work to get the pb from under it, they can not avoid tripping the trap, ....
in the 70's, lived in Cal. and found signs of mice in my garage(never saw them), that afternoon I set one trap with pb and checked it and re-baited it several times throughout the night,..... by the morning I had killed 13 mice and three different times had two mice at once in the trap, .... never saw another mouse or signs of them as long as I lived there,...peanut butter works better than anything, ..... some traps today have little scented blocks, smear pb on those as well, it'll draw them to the trap better than the scented block will ...
