Control fleas inside your home without sprays with the TERRO Flea Trap. This trap detects, monitors, and controls flea infestations by luring fleas from up to 30 ft. away using light and heat as attractants. Fleas leap into the trap where they get stuck fast on a SuperGrabber replaceable glue board. The glue boards will also capture other insects that attempt to cross its path. This trap also features a protective canopy that keeps objects, people, and pets from coming in contact with the sticky glue board. The TERRO Flea Trap is easy to use. To set up, simply extend the canopy until it clicks into place, insert the glue board and remove the release paper, then turn on the light. Place the trap on the floor in an area where fleas are common - typically where your pet spends a lot of time. Put in a fresh glue board every two to four weeks. This trap includes two glue board inserts, with additional refills sold separately. Why are fleas so eager to investigate the TERRO Flea Trap? Adult fleas sense heat, which to them indicates a warm-blooded animal that they typically use as a host. By simulating the warmth of the host, the flea trap attracts fleas from where they live and hide. If you're a pet owner, you can use the TERRO Refillable Flea Trap year-round as an early detection device, luring these parasites out of upholstery, carpeting, and cracks.
