Erroneously noted in 2008 Main Catalog as OMRI listed, when it is not. Havahart Deer Repellent Keep deer, rabbits and squirrels from browsing on plants, flowers, hedges, buds, shrubs, grass, bulbs and small trees year-round. Do not use on edible crops. This safe and all-natural deer repellent is doubly effective compared to other deer repellents as it utilizes a dual defense system including both a powerful odor and taste. Most other products use only one barrier method. Active ingredients include putrescent whole egg solids, capsaicin and garlic. Weather resistant formula. One thorough application lasts up to 3 months, but respray upon evidence of any browsing activity. Use 4 oz with 28 oz of water to make a quart of spray mixture; treats approximately 4000 sq ft.
