A trap should be set directly under the hole at each end of the box. Keep the trap pan tight to prevent the mice from setting off the trap. Traps set in old brush piles, under outbuildings, under fences and along stone walls also are suggested, since the weasel is likely to investigate any small covered area. Trap sets should be protected by objects such as boards or tree limbs to prevent harming other forms of wildlife. Weasels also can be captured in live traps.
Fresh meat is suitable bait.
