They can bug, bother, and hide, but ants, cockroaches, crickets, earwigs, fleas, and silverfish are no match for Ortho® Bug B Gon® Diatom Diatomaceous Earth Multi bug killer. This formula is made with diatomaceous earth, which means it kills pests that come into direct contact with the spray. It can also pass from bug to bug, so it helps control pests that don’t come into direct contact, too. Spray directly on bugs and in indoor and outdoor areas where pests are found: behind and under appliances, around pipes and drains, in attics and basements, and around doors, windows, foundations, and patios. For hard-to-reach spaces, attach the included extension tube before spraying.
