With DynaTrap StickyTech Glue Card Refills, you can enjoy non-stop protection from fruit flies, gnats, moths, mosquitoes, and more. Replacement glue cards are essential to keep on hand to ensure you're always protected. To use, simply peel the backing off a StickyTech glue card and insert it into the basket of your DynaTrap Indoor Insect Trap. Plug the trap into a wall outlet or USB port near common insect hotspots, including near houseplants, exterior doors, pet areas, in kitchens, bedrooms, and other areas of your home. Once drawn into the trap, insects get stuck fast to the StickyTech glue cards and are securely held in the basket until the time of disposal. Since the glue card is hidden inside a discreet basket, it keeps insects trapped and out of sight. For best results, replace the glue card when it becomes full, or every 30 days
