Sticky Roll Deluxe Kit, includes 1000ft. of Sticky Roll, take-up reel, 3 pulleys, hand crank, mounting rails, all necessary hardware. (Refill with 1000ft. roll.) Non-toxic, non polluting amazingly effective Sticky Roll catches, controls and eliminates flies because itβs based on their natural habits. Flies follow the warm updrafts in rooms and barns, seeking a resting place near the ceiling. They become entrapped in Sticky Roll, then become an irresistible attractant to other flies. No baits, toxins or pheromones are necessary. Soon the tape is black with dead flies. When a length of tape is full, crank it up, flies and all, onto the disposable take-up reel. Fresh tape is rolled out at the same time, ready to grab more flies.
