RESCUE! POP! brings you the Fly Bait for getting rid of gnats, house flies, blowflies, and other types of flies. You can also use it as a fruit fly trap to get rid of fruit flies. This outdoor pop fly trap is easy to use, and all you have to do is empty the contents of the foil pouch into the trap and add water. Lured by the scent of this flycatcher, the flies enter through the yellow top cap and drown in the water. The bug zapper can be refilled over and over again with single-use pouches. The RESCUE! POP! fly trap is the best outdoor fly trap bag to prevent flies from coming into the house.
