Manna Pro Pure DEfense(TM) Diatomaceous Earth is the natural way to get rid of pests like fleas, cockroaches, ants, earwigs, beetles, and other crawling insects. Diatomaceous earth is a very hard material that punctures the exoskeletons of insects at a microscopic level, leaving them to dehydrate and die within 48 hours. This means that it doesn't require poison to work, making it a safer product for your family and pets. It also means that insects cannot develop resistance to the formula. | MannaPro Pure DEfense Diatomaceous Earth | Size 4 lb
