The RESCUE! Non-Toxic Disposable Fly Trap catches common nuisance or filth flies, hundreds of the most prevalent species including house flies, false stable flies, blow flies, blue and green bottle flies, flesh flies, face flies and many others. Inside the trap is a bait that flies find irresistible. This attractant is comprised of food and feed ingredients, and other food flavorings generally recognized as safe. The attractant dissolves and activates when water is added to the bag. Lured by the scent, flies enter the trap through the yellow top cap and drown in the water. Has been proven to ctach up to 20,000 flies. RESCUE!’s goal is to design, manufacture and market the safest, most effective pest control solutions available. Our products are the result of exhaustive and ongoing research and development, decades of experience and a commitment to solutions that respect the environment without sacriï¬cing results. Established in 1982, RESCUE! pest management products have never used poisons or toxicants to kill pest insects. Once inside the trap, the insects cannot ï¬y out and die either by drowning (top chamber) or dehydration (bottom chamber).
