Spider mites destroy plant cells by sucking out their contents and 217C unique formula works by providing a barrier which is harmless to the plant, but fatal to the mites. 217C kills the spider mites eggs and kills the life cycle by coating the eggs with an oily shield that blocks respiration to the egg; therefore no hatching will occur, they will just dry out. 217C is made up of 100% pure rosemary botanical extracts highly water soluble. We process raw certified organic botanicals and herbs in-house, ensuring oils and terpenes have a consistent potency across all of our products. The botanical extracts are all food grade GRAS (generally recognized as safe when used as directed) materials, that are fully biodegradable, and not toxic to animals. It is exempt from EPA registration under minimum risk pesticide exempted under FIFRA section 25(b).
