Shake-Away Small Critter Repellent Granules use fox urine to effectively, safely, and naturally repel rabbits, groundhogs, possums, woodchucks, and other small critters from damaging flower beds, vegetable gardens, and ornamental plants. This OMRI Certified organic solution takes advantage of the typical prey animals' instinctual fear of a predator, without causing any harm. Spot-treat the area twice a week for the first two/three weeks, then twice a month for maintenance. Safe for both animals and plants, this 28.5 oz. product covers up to 10,000 sq. ft. for reliable protection.
