Mosquito Barrier is a strong liquid garlic that's diluted in water to deliver a three-pronged attack against annoying insects. First it kills the adult mosquitoes on contact. Second the garlic-coated plants keep mosquitoes out of the area. Last it suffocates any mosquito larvae in standing water, such as puddles or depressions in lawns. Safe to use around children, pets and plants. Odor disappears in about 30 minutes. One container treats 5 acres. 1 gal. NOTE: Cannot be sold or shipped to Idaho, Kansas, Wyoming, U.S. Territories or International.
