The Raid Yellow Jacket, Wasp, and Hornet Trap Lure Refill Pack are equipped with a tested and proven food-based lure that attracts once water is added. The Raid Yellow Jacket, Wasp, and Hornet Trap Lure are easy to use and effective at controlling flies week after week. This lure refill pack is to be used with the Raid Wasp Jar. Carefully open the package and pill out the white lure pouch inside. Next, unscrew the yellow lid from your Raid Reusable Yellow Jacket, Wasp, and Hornet Trap. Cut open the white lure pouch and pour the content inside the trap jar. Add 2 1/2 cups of fresh water inside the trap base and replace the yellow lid. Hang or place the trap on the table. Wash hands thoroughly after handling. Store in a cool, dry place inaccessible to children and pets until ready to use.
