Deer-Off is an all-natural, bio-degradable deer deterrent made from eggs, garlic and hot pepper. EPA-approved for use on all plants, shrubs, flowers - even food crops. Unlike other organic repellents, Deer-Off forms a double barrier, both odor and taste, between plants and hungry animals. Use Deer-Off at least once a season for best results; each weather-proof application lasts three months. Deer-Off is also effective against rabbits, voles, moles and squirrels. Convenient, ready-to-use spray bottle and cost-effective concentrate are available.
