Messinas Deer Stopper can be used to discourage deer, moose and elk from devastating plants (including gardens, shrubs, fowers and trees), bedding down and rubbing against tree trunks. With an abundant food supply and protection from the elements, deer will forage and feed leading to crop loss and other plant damage. To prevent further home and garden harm, apply Messinas Deer Stopper to key areas. Our humane and safe Messinas Deer Stopper creates a sensory barrier that works by smell and taste and can be applied every 30 days regardless of weather or watering. It is pleasant to use, dries clear and odor free and is safe to use around fruits and vegetables.
