A snap style vermin trap disposed on a planar platform having an enclosed bait chamber and a partially enclosed actuation chamber. The bait chamber and the actuation chamber are separated by a perforated vertical trip plate. A detachable housing resides about the platform. The snap trap mechanical components are housed in the bait chamber. The design prevents the vermin from ever reaching the bait or contaminating the bait chamber. The vertical trip plate disadvantages the vermin physically and the housing further prevents escape.
