SNS-217 Spider Mite Control is made up of 100% pure Rosemary botanical extracts. The botanicals are all food grade GRAS (generally recognized as safe) materials.

Spider mites destroy plant cells by sucking out their contents and SNS-217's unique formula works by providing a barrier which is harmless to the plant, but fatal to the mites. SNS-217 Spider Mite Control kills the spider mite eggs as well by coating the eggs with a oily shield that disrupts the respiration to the egg; therefore no hatching will occur, they will just dry out. Trust us, this is terribly potent stuff. Mites hate it, your plants will love it! It's a screaming deal too! $32.50 for 1.3 ounces. Sign me up!!
