Just Scentsational Wolf Urine Predator scent has long been known to trigger the fight or flight response in small animals of prey. The larger the predator, the larger the prey that can be intimidated by the scent. The wolf is one of the largest common predators, so its scent is particularly frightening to many animals and scares them off quickly. Place around the yard in areas where small unwanted pests are an annoyance. Repeat the application every couple of weeks or after heavy rains. Wolf Recharge Scent available in 16oz bottle.
