Designed and field-tested by trapping professionals, the Havahart x-small 1-door live animal trap is built to ensure a quick, safe trapping experience, every time. Thanks to its careful construction, it can be used as a flying squirrel trap, weasel trap, chipmunk trap or virtually any small rodent trap, because these tiny animals can't outsmart it. The trip plate is sensitive enough that even the lightest animals can effectively trigger the door closed and the mesh openings are smaller than competing traps, so little critters cannot steal the bait.
