Amdro Ant Block Home Perimeter Ant Killer Granules, 24 oz. are specially designed to provide effective ant control around your home. By simply applying these granules around the perimeter, you create a protective barrier that prevents ants from entering your living space. Worker ants are attracted to the granules and carry them back to their colony, mistaking them for food. Once the queen ant consumes the bait, the entire colony is eliminated. This product is for use on lawns, landscaped areas, and around structures, targeting carpenter ants and 14 other ant species with its active ingredient Hydramethylnon. The ready-to-use 24 oz. pour bottle covers up to 1,080 linear feet, making it a convenient and efficient solution for ant problems. Model Number:
