The Garden Scentry by Just Scentsational is the humane and environmentally friendly way to create a territorial boundary. Predator scent has long used by hunters and trappers to mark the grounds and has been known to create a territorial deception. 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. Use our coyote urine as a recharge for our Scentry Stones, sold separately, or by themselves Place the scented Garden Scentry where you see trespass. The Garden Scentry is totally safe around humans and will not cause harm to pets or wildlife. For best results, in large gardens, place one every 12 to 16 feet apart. The Garden Scentry has the ability to protect your precious flowers and vegetables. The Garden Scentry is made of an all-natural absorbent stone that you infuse with one of our Just Scentstational predator scents. Recharge scent is available when the Garden Scentry needs a recharge. For best results, in large garden areas, place one every 12 to 16 feet apart. Good for many months of outdoor use. Time depends on outdoor weather conditions.
