Tackle flea problems within your home with the TERRO T230 Indoor Electric Flea Trap and Killer, designed to provide an effective trap that kills fleas in house without the use of sprays. The trap utilizes a combination of light and heat to mimic a warm-blooded host, attracting fleas from up to 30 feet away. Once the insects are lured in, they become immediately stuck on the SuperGrabber glue board. This indoor electric flea trap is refillable and features a protective canopy to avoid accidental contact with the sticky surface by people or pets. Using the TERRO Flea Trap is a breeze: simply insert the glue board, plug it in, and place the fly traps indoors where fleas are common, such as in pet sleeping zones or upholstery-heavy spaces. Replace the glue board every two to four weeks to maintain optimal effectiveness. Each set includes two glue board inserts, with additional refills available separately.
