This refill consists of a continuous 1000-foot length of quarter-inch wide white adhesive tape, made to be used with the Sticky Roll deluxe reel-to-reel hardware kit (sold separately). The tape mounts overhead, where flies naturally congregate after hatching, feeding, or when the weather cools, and adheres them on contact. As flies become trapped they release chemical signals that draw additional flies to the same area, adding to the tape's capture over time. The white surface eventually darkens as it fills with trapped insects and can be advanced to expose a fresh section using the reel mechanism. The system contains no insecticide and produces no chemical residue, making it suited to dairy barns, horse stables, kennels, zoos, veterinary areas, and food processing spaces. Installation is straightforward for anyone with the compatible deluxe hardware already mounted in place.
