Bait your moustraps with cotton wool, the mice value it as a nesting material and it doesn’t go off or attract creepy crawlies. In our case it has been just as effective, i.e. not at all. We have those humane traps that have a see-saw action and don’t harm the mice they catch. We’ve only caught two mice and in both cases the mouse was taking refuge from either the cat or a broom.
