Garlic Barrier (Quart) is an all-natural garlic concentrate that repels insects rather than killing them, so it is best applied before pests establish. It becomes odorless within minutes of application, even indoors, and will not affect the taste of edible plants. It is exempt from Federal and California EPA registration, so no Pest ID number is required.
