I've tried two different types of humane trap but neither caught a mouse.

I meant to add that the traps were quite small. I baited them with
peanut butter, peanuts, chocolate, cheese etc - but with no success. I
suspect the mice weren't prepared to squeeze themselves into the small
space that the shop-bought traps provided.

A better option may be a home-made trap.
