Our Green Zone™ logo is used on products that feature plant- or mineral- based active ingredients such as plant oils, borax and silicon dioxide. It is also used on our non-pesticidal traps. Our plant oil based-products are classified by the Environmental Protection Agency as Exempt from federal pesticide registration due to minimum risk. Silicon dioxide is FDA GRAS (generally recognized as safe) listed, and borax is allowed as a pest control ingredient under the USDA National Organic Program. Remember to always read and follow label directions.
