It forms a natural barrier lasting up to 7 days, is safe for use around children and pets, and is EPA exempt under FIFRA 25(b), making it perfect for organic gardening and safe pest control up to harvest. ## Description PC kills and ends the life cycle of Aphids, Ants, Earwigs, Thrips, Spider Mites, Eggs, Larvae & more. The properties of SNS PCTM disrupt the insect cell structure and respiratory membranes causing the insect to dehydrate, suffocate, and die. Control of the insect is due to a natural barrier that causes surface tension changes (feels unpleasant when they walk on it) for up to 3-7 days then naturally breaks down. SNS PCTM™ kills eggs and larvae by coating them with a shield which causes dehydration and prevents respiration. Therefore no hatching will occur, they will just dry out. PC is made up of 100% pure peppermint 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. It is exempt from EPA registration under minimum risk all natural pesticide exempted under FIFRA section 25(b). It can be used on a wide variety of plants, fruits, and vegetables. Review: A staple in my garden - This has really worked for me to keep the spider mites and such off my new fruit trees. I've also used it on okra successfully. It doesn't kill sugar ants, but it does kill newly hatched squash bug nymphs, so bonus there. ## Features - Causes insects, larvae & their eggs to dehydrate & die - Kills insects, their larvae & their eggs to end life cycle - Can be used up to harvest (0-Day REI) - Safe around children & pets when used as directed - Can be used for organic production, EPA Exempt FIFRA 25(b) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CSH59GHF | | Best Sellers Rank | #216,600 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #585 in Insect & Pest Repellent Spray Concentrates | | Brand | Sierra Natural Science | | Brand Name | Sierra Natural Science | | Customer Reviews | 5.0 out of 5 stars 3 Reviews | | Included Components | 1 insecticide concentrate | | Item Form | Oil | | Item Volume | 4 fluid ounces | | Item Weight | 4 ounces | | Manufacturer | Sierra Natural Science | | Manufacturer Part Number | 31639 | | Material Feature | Organic | | Material Features | Organic | | Model Number | 31639 | | Number of Items | 1 | | Scent | Unscented | | Scent Name | Unscented | | Size | 4 Fl Oz (Pack of 1) | | Target Species | Fungus | | UPC | 850046870118 | | Unit Count | 4 Fluid Ounces | ## Product Details - **Brand:** Sierra Natural Science - **Item Form:** Oil - **Item Volume:** 4 fluid ounces - **Material Feature:** Organic - **Scent:** Unscented ## Images ![Sierra Natural Science - PC - Concentrate Pouch - 4 fl oz (118 mL) Makes up to 32 fl oz - Image 1](https://m.media-amazon.com/images/I/51WVKYaiT6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A staple in my garden *by R***N on July 29, 2025* This has really worked for me to keep the spider mites and such off my new fruit trees.
