Predator scent has long used by hunters and trappers to mark the grounds and has been known to create a territorial deception. Dogs love the scent of other canines and love to mark their own territory. Urines are the perfect illusionary scent. Predator urine scent is particularly noticeable to many small animals. Place around the yard and garden in desired areas to create a perimeter of scent. Repeat the application every couple of weeks or after heavy rains. Use as a recharge for our Scentry Stones, sold separately, or by themselves. Fox Recharge Scent available in 2-2oz foil packs
