Tree Guard® is a pre-mixed, ready-to-use deer repellent that sprays on milky and dries clear. The active ingredient, Bitrex™, makes the coated plant taste bad. A detection agent lets the deer know the plant is treated. Tree Guard® leaves a clear sheen which resists wash-off from rain and snow. Tree Guard® may be used on any non-food plant, and poses minimal risk to deer, plants, people, and the environment.  Tree Guard® from Becker Underwood is known throughout the deer repellent industry as ‘the one that works’.  Click here to order Tree Guard® or click here for more information on Tree Guard®.
