Mr. Stickys super Size Sticky Roll brings a full 2500 ft. of nonpolluting, nontoxic Sticky Roll to the war on flies. Sticky Roll is a reel-to-reel system of sticky tape that really catches flies! When flies first hatch, after feeding or when the weather cools, flies tend to congregate over head and search for a light-colored ledge. Once entrapped in on the Sticky Tape, they produce stress chemicals which are irresistible to other flies. When a length of tape is full, wind it up, flies and all, onto the disposable reel and throw it away. Sticky-Roll is a safe and effective system that is easy to install for use in animal premise areas, veterinary and food processing areas — anywhere flies are a problem! USDA testing showed that Sticky Roll captured 92% of available flies, an astonishing performance for a pesticide and attractant free control system. Sticky Roll tape is a quarter-inch wide. Deluxe Super Sized System features a 2500 ft. roll, an empty take-up reel, all necessary mounting hardware, pulleys and hooks for installing a network of tape throughout a large enclosure. Wt. 8.5 lbs.
