Sterling International RESCUE! POP! Fly Trap Attractant
The RESCUE! POP! Fly Attractant works inside the RESCUE! Reusable POP! Fly Trap to lure common nuisance or filth flies. Each refill packet contains one application that generally lasts two weeks to a month. Just drop the water-soluble pouch into the trap container, add water to the fill line, replace the top, and hang or place the trap outside near a fly source.
