The present invention relates generally to traps for bed bugs and roaches. Bed bug infestations have taken a dramatic upturn in the last several years and roaches are among the oldest surviving creatures on earth. This trap takes a novel approach to luring bed bugs and/or roaches out of their hiding places, using a live warm blooded animal to entice them into the trap and killing them once they enter the trap by cutting their legs off with a rotating cutter blade, shearing off any protrusion through the perforations in an interior wall.
