Query: Can work, but only on small rodents.

This trap can actually catch mice, but if they aren't small, will only injure them. It also leaves a wiggling tempting snack for other animals to eat, who then take the mouse AND trap to locations unknown. Trap is not selective and will kill or injure anything that trips it. The most selective and humane way to trap is to use a Havahart trap, then euthanize only the problem animals with ether (found as "starting fluid" in automotive stores). Ether is a potent anesthetic which was used on humans in early medical procedures. It's also extremely flammable so take great care.
