The company I hired showed up when I wasnt home and applied Delta Dust around the exterior during a rain storm. When I called and asked they told me it was okay and legal and the rain wont effect it.
While we cannot comment specifically on another person's application, it's not illegal to apply Delta Dust Insecticide in the rain. Delta Dust Insecticide is waterproof. Our concern is that if the rain storm was bad enough, it could potentially wash the product away.
