Shake-Away 28.5 Oz Deer Repellent Granules are an OMRI Certified organic solution to large pest animals. This scent-based repellent takes advantage of natural prey-predator instincts, using Coyote Urine to frighten deer, elk, javelina, armadillo, and more. Spot-treat activity areas twice weekly for the first two/three weeks, then twice a month for maintenance to reduce and eliminate pest damage. Each application covers approximately 10,000 sq. ft., remaining effective in normal weather conditions and irrigation.
