Formulated for professional use, Dear Scram is a safe yet effective repellant that trains deer to stay away from protected areas. It's made from animal by-products to imitate the smell of a dead deer, which stimulates a sense of fear and a strong avoidance reaction. Great for use around plots, garden beds, rows of trees, shrubs, flowers or other edibles at risk for deer browsing damage. Sprinkle liberally starting 15" from the edge of the landscaped area, making a 20" band around the perimeter. Each application should last approximately 30 days; re-application may be required after periods of extremely heavy rain.
