It helps me to save my plants from any above-ground pests (when used as a foliar spray) and in-ground, too (soil drench). I add a small amount with every other watering. Works for plants in leca. ### ⭐⭐⭐⭐⭐ Sns 203 *by A***Y on March 3, 2026* Sns 203 using as pest prevention on houseplants. I rotate with systemic granules! ### ⭐⭐⭐⭐ Good gnat control without chemicals *by T***D on May 16, 2013* The SNS 203 pesticide concentrate works as described. For indoor plants it has gotten rid of most of the gnat population and doesn't have harsh chemicals. Use of this product in combination with letting soil dry completely before watering has eliminated the gnat population. I needed two applications of this product to rid the soil of gnats. DO TEST on your plants first. It did have negative effects on my ficus plant, so I am gathering it shouldn't be used on plants that have a milky sap. I haven't confirmed this with the company, but don't use on a ficus plant if you can avoid it. ## Frequently Bought Together - Sierra Natural Science - SNS-203 - Pesticide Concentrate - 16 oz - Sierra Natural Science - SNS-209 Systemic Concentrate -1 Pint - Bonide Captain Jack's Deadbug Brew Ready-to-Use Spray, 32 oz Outdoor Insecticide and Mite Killer for Organic Gardening --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/21560143-sns-203-pesticide-concentrate-16-oz](https://www.desertcart.co.th/products/21560143-sns-203-pesticide-concentrate-16-oz) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-11*
