Cluster Buster 5 Pack - Insect Controls | Gardener&s Supply Company

The Cluster Fly Buster is a natural way to eliminate unpleasant cluster flies indoors. Simply attach one of these inconspicuous traps to each window where flies congregate with the sticky strips included; flies enter and “drown" in finely ground eggshells. No buzzing, no odors, easy disposal. Each trap holds 1000 flies and remains effective for two to four years.
