RESCUE! Outdoor Disposable Fly Traps are our top pick in this category. These disposable outdoor hanging fly traps get rid of a variety of common flies, including hundreds of the most prevalent species.
These traps use a scented attractant bait that is very effective at luring flies. After being drawn by the lure, flies enter the trap through the cap and drown in the water. Simply add water to activate the bait and hang the trap outside, at least 20 feet away from any living spaces.
