You are essentially buying a well-lit hotel for any flea that might randomly jump onto the sticky glue in the middle of the night. You'd be equally well-served by putting a piece of duct tape on the floor and hoping one of the critters chooses to inadvertantly commit suicide by plunging onto it. Dont throw away your money on this well-marketed junk. It doesn't attract fleas at all - it's literally just an expensive holder for sticky tape, with a light bulb to remind you how much money you just wasted. That it catches fleas in the quantities reported by top reviewers gives me great concern for what can only amount to a Biblical flood of fleas infesting their homes.
