Fend Off Deer and Rabbit Repellents protects plants from deer browsing and further deer damage using a garlic odor that deer can't stand. Like pepper, garlic is a deer-resistant plant that deer don't like smelling or tasting. Each t clip slides gently onto a plant or garden fence for use. When deer gets close to the plants it will smell the odor and repel deer, elk, and rabbits. The odorous deer repellent mixture in the clips is made of food-grade organic material. The Fend Off clip will last 6-8 months and is perfect for use in trees, vegetable gardens, and flowerbeds. Each pack of deer repellent contains 25 clips.
