Garden-safe and pet-friendly! Uses predator urine granules to cause deer to instinctively leave an area where they detect a predatory threat. Humanely mimics nature’s warning and creates a natural boundary to repel deer. There is no mixing of obnoxious sulfur liquids, or any residual odor in the area that is detectable by humans. 100 percent natural, certified organic, and the only products using predator urine to be EPA-registered. 1 ounce covers 30 linear feet. Just sprinkle lightly around the area you’re trying to protect. Only a few shakes communicate the scent of a predator to deter deer.
