The Havahart® Critter Ridder® granules protect your lawn and flowerbeds from wildlife and stray pets. This treatment harmlessly repels animals from your yard in two ways. First, it overwhelms their sense of smell and then it assaults their sense of taste. Thanks to its highly potent active ingredients, Critter Ridder® is fast acting and animals quickly learn to avoid the area they won't want to experience those sensations again. Use Critter Ridder® against raccoons, groundhogs, cats and dogs. The granules in this 2 lb container offer 30 days of critter protection.
