Keep critters away by overwhelming their senses. Without harming the animal, the spray formula repels through the sense of smell and taste with the use of three intense ingredients- piperine, oil of black pepper, and capsaicin. Critter Ridder Animal Repellent can be used outdoors in places such as lawns, flowerbeds, sheds, near trashcans, and more. Critter Ridder is easy to use, either apply by hand or with a long spreader.
