This 100 foot barrier ribbon is pretreated with Deer Stopper. When deer, elk or moose approach the perimeter protected by this 100 foot black ribbon, they will sniff it and walk away. Ideal for flower/vegetable gardens and small planting areas. It will not wash off after a heavy rainfall and lasts for 30 days. It can be reused over and over each season by treating it with more Deer Stopper (H461A).
