With Safer Home Indoor Plug-In Fly Trap Refill Packs, you can enjoy non-stop protection from flies, fruit flies, moths, gnats, and more. Simply peel the backing off the StickyTech glue card and insert it into the trap. Plug the trap into a standard outlet near common insect hotspots, including near houseplants, exterior doors, pet areas, in kitchens, bedrooms, and other areas of your home. Once drawn in by the light of the trap, insects get stuck fast to the StickyTech Glue Cards and are securely held until the time of disposal. The unique glue placement on the wall side of the card keeps insects trapped and out of sight. StickyTech Glue Cards contain no chemical insecticides and are the ideal choice for homes with children and pets.
