Deerbusters all-natural concentrated deer repellent uses a blend of citric acid, distilled water, eggs, garlic, and white pepper to end deer browsing on your garden. This deer repellent concentrate is particularly effective against deer as it repels by odor and taste--odor deterrents will dissuade them from chewing before they start, and taste deterrents will teach them that there's nothing appetizing about your garden. When diluted, this repellent for deer control makes a foliar spray for flowers, shrubs, and trees, and won't cause an offensive odor, residue, or discoloration in your plants. Our rain-resistant formula will last up to 3 months per application. 2.5 gallons of concentrate will treat 3000-4000 four foot shrubs or flowers, and will make 20 gallons of repellent.
