Using rosemeric acid from rosemary, it creates a natural barrier throughout the plant to repel and kill a wide range of pests safely and effectively. Certified organic, biodegradable, and safe for use around children and pets, it supports healthy plants right up to harvest. ## Description Insects destroy plant cells by sucking out their fluids or chewing up the cell walls. 209’s unique formula works by allowing the plant to uptake a small amount of rosemeric acid from the rosemary plant. As the plant distributes the rosemeric acid throughout its cell walls, a barrier is soon constructed that is harmless to the plant. When an insect starts to suck or chew on the plant it comes in contact with the rosemeric acid and causes the insect to stop eating and move on. 209 is made up of 100% pure botanical extracts that are 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 pesticide exempted under FIFRA section 25(b). It can be used on a wide variety of plants, fruits, and vegetables. 209 is powerful organic systemic insecticide which repels and kills spider mites, broad mites, russet mites, root aphids, gnat larvae, fungus gnats, white flies, cabbage maggots, and most boring insects. Review: Amazing pests control for indoor plants - So far so good, it was easy to use the instructions were clear to use. I diluted the sns-209 systemic with water and fertilizer and my plants love it the best part is it repels those nasty pests from attacking my indoor plants. The smell it’s not that strong which I like. If you are dealing with mealybugs , thrips, fungus gnats and spider mites this might be the solution to keep them away from your plants. Review: Safe and works! - SNS 209 is a safe and effective organic pesticide. Was able to get rid of thrips and now use every watering as a preventative. Haven't had any pests since. Also seems to be the only systemic that is effective for spider mites that I am aware of. ## Features - Preventative treatment to protect the whole plant against insects - Protects your plant from roots to whole plant - Safe up to day of harvest when used as directed - Can be used for organic production - Safe around children & pets when used as directed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CSHKZTWY | | Best Sellers Rank | #5,538 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #56 in Insect & Pest Repellent Spray Concentrates | | Brand | Sierra Natural Science | | Brand Name | Sierra Natural Science | | Customer Reviews | 4.4 out of 5 stars 361 Reviews | | Included Components | 1 concentrated pouch | | Item Form | Oil | | Item Weight | 1.25 Ounces | | Liquid Volume | 1.25 Fluid Ounces | | Manufacturer | Sierra Natural Science | | Model Number | 31637 | | Part Number | 31637 | | UPC | 850046870088 | | Unit Count | 1.25 Fluid Ounces | ## Product Details - **Brand:** Sierra Natural Science - **Item Form:** Oil - **Item Weight:** 1.25 Ounces - **Liquid Volume:** 1.25 Fluid Ounces - **Unit Count:** 1.25 Fluid Ounces ## Images ![Sierra Natural Science - 209 - Concentrate Pouch - 1.25 fl oz (37 mL) Makes up to 32 fl oz - Image 1](https://m.media-amazon.com/images/I/51l-aOLFoXL.jpg) ![Sierra Natural Science - 209 - Concentrate Pouch - 1.25 fl oz (37 mL) Makes up to 32 fl oz - Image 2](https://m.media-amazon.com/images/I/51iG7lGkleL.jpg) ![Sierra Natural Science - 209 - Concentrate Pouch - 1.25 fl oz (37 mL) Makes up to 32 fl oz - Image 3](https://m.media-amazon.com/images/I/51cX3NcolDL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing pests control for indoor plants *by Y***N on May 12, 2026* So far so good, it was easy to use the instructions were clear to use.
