Unlike other deer repellents that require direct application to protect plant material, this unique Deer Stopper Plotsaver Deer Barrier System Starter Kit keeps deer at bay by protecting the entire perimeter of your property. Simply string the absorbent poly-tape ribbon around the perimeter of plants at 30" off the ground (deer muzzle height), then spray ribbon with Deer Stopper repellent. 39"L support stakes (Item # 145522) and ribbon clips (Item # 145523) are sold separately. Replacement white deer ribbon also available (Item # 145521).
