If you've used and liked the Mr. Sticky fly tape, you'll love these systems for home and barn. They're nonpolluting, nontoxic, and amazingly effective. They work especially well when mounted over-head. Once flies are trapped (USDA testing shows Sticky Roll captured 92% of available flies!), they emit stress chemicals that attract other flies. When tape is full, just wind it up (flies and all) and throw it out. Deluxe kit is designed for large barns and stables. Kit includes 1000' sticky tape roll, take-up reel, hand crank, heavy duty mounting rails, screws, and 3 pulleys to install an "around the barn network of tape," the most effective way to use this system. 600' ($27.95) and 1000' ($35.95) refill tape rolls are also available.
