With Safer Home Indoor Fly Trap Extra Large Refill Glue Cards, you can enjoy non-stop protection from flies, fruit flies, moths, gnats, and more. Simply remove the adhesive liner and insert the glue card into the compatible Safer Home Indoor Fly 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. The 50% larger catch area (compared to standard Safer Home Glue Cards) makes these refills perfect for larger spaces and high-traffic areas. Once drawn in by the light of the trap, insects get stuck fast to the Extra Large 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. For best results, replace every 30 days or sooner if full.
