## Overview

Sierra Natural Science 217C is a potent, 100% rosemary-based botanical concentrate that kills spider mites, broad mites, russet mites, and their eggs by suffocating them with an oily barrier. EPA exempt and safe for children, pets, and beneficial insects, it offers a zero-day pre-harvest interval and is fully biodegradable. This 6 fl oz concentrate makes up to 32 fl oz of spray, delivering professional-grade pest control without harmful chemicals.

## Description

217C kills spider mites, broad mites, russet mites and their eggs. 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). It can be used on a wide variety of plants, fruits, and vegetables.

Review: Very effective - Used it to control a spider mite infection in an indoor garden. Used two applications, but there was no sign of life after the first. I’ve had trouble safely eradicating mites before without damage to plants, consumer or environment. The SNS 217c was instant kill. No chemicals. Just rosemary extract. I found the rosemary scent very pleasant. Not sticky or messy at all. Didn’t hurt the plants at all. The only way I would like it more is if it were less expensive. It’s a great product and it’s priced accordingly.
Review: Works better on spider mites than anything else I've tried. - This stuff is pricy but better on spider mites than all the other products I've tried. It's hard on blooms and stunts bloom growth for a few days. Try to catch infestations before your plants flower. Spray every bit of the plant, and repeat after a few days at least twice. Mites lay eggs on the underside of leaves, if you miss a spot they will come back! A pint doesn't go very far but don't be stingy with it. It makes 6 pints of spray. I keep a pint of concentrate in the fridge so I can respond quickly at the first sign of mites. They multiply unbelievably fast.
