The efficient fly paper is on a practical roll. It can be easily hung in places where flies are commonly found using the metal hook. With the adhesive side facing down, the paper can also be stretched horizontally directly over cows, pigs, or calves. An additional visual attraction is created by simulating landing spots. It can be reliably used in various locations, such as in the barn, milk room, production hall, storage room, house, and many other places.
