M510 VICTOR FLY RIBBON | TERRO fly magnet fly paper traps use a sticky ribbon to attract and trap flies and other airborne insects. Fly magnets come in cardboard tubes that, with a twisting pull, expose a sticky surface to trap flies. Each tube includes a hanging ribbon and thumbtack for easy installation inside barns, at campsites, on porches, in kennels and at vacation homes. This fly paper requires no baiting, has no stinky odor and won't create a mess. When the trap is full, drop it into a bag and throw it in the trash. Each package contains four TERRO fly magnet traps.
