Doktor Doom Spider Mite Knockout features a high concentration of the naturally-occurring insecticide pyrethrin, a very effective substance used to control aphids, spider mites, whiteflies, leafhoppers, Japanese beetles, and more. Its 0.2% pyrethrin concentration is ten to twenty times that of comparable pyrethrin-based insect control products! This powerful spray can be used indoors and out and is safe to apply on food crops up to one day before harvest.
