Doktor Doom® Spider Mite Knock Out® is a .20% pyrethrin formula. This formula is 19 times stronger in active ingredient pyrethrin than any soap based insecticides and 10 times stronger than any formulations that contain pyrethrin & piperoynl Butoxide. Piperoynl Butoxide is a synergist which enhances the killing power of pyrethrin and it is not approved for organic gardening. Pyrethrin is approved for organic gardening with some restrictions - refer to OMRI (Organic Material Review Institute), for more information.
Unlike soap based products which need to be applied liberally to the plant in order to drown the insects, Doktor Doom® Spider Mite Knock Out® kills the pests on contact with just a light misting on the foliage.
