A cockroach trap includes floor molding that is hollowed out in back to provide a passage running the length of the molding. Slits along the bottom of the molding allow a cockroach to enter the passage where it steps onto a touch-sensitive switch. The switch causes a control to momentarily energize a vacuum that sucks the cockroach from the passage and deposit it into a chamber where it can be destroyed or stored alive.
