Havahart Deer Off 32-oz. Deer, Rabbit, & Squirrel Repellent Concentrate features a patented, dual-deterrent system that effectively repels animals by targeting their keen sense of taste and smell. With a high concentration of putrescent egg solids, Deer Off contains four times more active ingredients than the original formula. Though the scent effectively keeps deer, rabbits, and squirrels away from the protected area, Deer Off dissipates and dries odorless to humans. In addition to using scent, Deer Off features a combination of garlic and capsaicin flavors that stop deer, rabbits, and squirrels from feeding on your plants and foliage. The weather-resistant formula lasts up to 90 days. There is enough formula to treat 400 ornamental shrubs 4’ tall or approximately 3,500 sq. ft. of plantings.
