Critter Ridder patented formula has been proven to repel groundhogs, skunks, dogs, cats, squirrels, raccoons, chipmunks and other nuisance animals. It easy-to-use, effective and economical. Just sprinkle the desired amount of Critter Ridder around the area you want to protect. For full perimeter protection, you can sprinkle it along a garden path or around a flower bed, or for a more targeted approach you can spot-treat areas on grass, or near ornamental plants, trees or shrubs, and even trash bags to keep unwanted pests away. Critter Ridder can also be used indoors around potted plants and non-living areas such as basements, cellars, storage areas, sheds and barns. Inside or outside, Critter Ridder delivers longer-lasting protection up to 30 days! Made with all-natural ingredients, Critter Ridder is OMRI Listed and compliant for use in organic gardening. Critter Ridder Animal Repellent Granular Shaker effectively repels dogs, cats, groundhogs, squirrels, raccoons, chipmunks and skunks using powerful scent and taste deterrents, including oil of black pepper, piperine and capsaicin. This powerful combination of active, all-natural ingredients works to irritate the animal immediately when it smells, tastes or touches it. This unpleasant experience drives the animal away unharmed, yet unwilling to return to the treated area. While Critter Ridder effectively repels animals, its scent is not offensive to humans.
