Attracts and traps fleas and other flying and crawling insects while you sleep. The photocell night light turns on automatically when the lights go off. Insects are drawn to the light where they become trapped by a sticky glue board that can be easily disposed of and replaced with a refill. Designed to plug into standard wall outlets, the trap hangs near the floor where it can be easily reached by insects. Contains no pesticides. Refills available.
