Rescue! TrapStik® for Flies uses new TrapStik® technology to lure flies with appealing colors and a multi-dimensional pattern. Flies are attracted by the colors and patterns on the TrapStik®, then get stuck to the adhesive surface. Traps are odor-free, pesticide-free, have a large catch surface and the adhesive holds up in the heat. The TrapStik® for Flies catches common house flies, cluster flies and fruit flies.
