Soaking in a full bowl or dish of water, with the plant inside also worked well. It takes time and repeated treatments, but it has helped my fungus gnat problem immensely. Will purchase again. I now use as a preventative. No smell, and completely pet safe. Easy to use. Review: Works as advertised - Seems to work.

Soaking in a full bowl or dish of water, with the plant inside also worked well. It takes time and repeated treatments, but it has helped my fungus gnat problem immensely. Will purchase again. I now use as a preventative. No smell, and completely pet safe. Easy to use. ### ⭐⭐⭐⭐⭐ Works as advertised *by L***O on June 19, 2026* Seems to work. Earwig population definitely drops a couple weeks after application. ### ⭐⭐⭐⭐⭐ In my Indoor Garden Whiteflies Fungus Gnats Thrips GONE *by C***E on August 2, 2026* I tried this with great reluctance because nothing stopped the invasion of whiteflies fungus gnats and thrips back in May when I bought it and sprinkled it on the top of the hydroponic reservoir of the hydroponic tower and I sprinkled it on top of the soil of plants in the grow room and covered it with 1/2 inch of soil mix and watered it in and bugs DEAD. And it’s three months later and no bugs and my yellow sticky traps are still free of a bug. I add more to the hydroponic reservoir after flushing it out and adding new water and nutrients and PH adjustments and EM1 I always add. I will keep using it with plants in my house. I switched to Miracle Grow Seed Starter Mix to prevent bringing in pests in my basement seed starting station. I make sure I brush my hair and clothes off before entering the house and I have a yellow trap by the door and above my kitchen sink I have basil as a trap plant and yellow trap. Yellow traps by the basement grow room entrance middle and exit. It’s safe for red wigglers and beneficial insects and bees when used in greenhouse. I didn’t bury it 1/2 inch and only sprinkled it on the soil surface and watered it so white flies had other ways to live but it killed fungus gnats and thirps dead in the greenhouse. I am finding success with Arber organic insecticide so far to kill whiteflies but in the greenhouse Nemaknights is my go to for soil management of pests. ## Frequently Bought Together - The Environmental Factor NemaKnights Slow-Release Nematodes - Biological Pest Control for Fungus Gnats, Thrips, & Whiteflies, Easy Shakeable Granules (280g, Treats Up to 50 Planters) - 40 Pack Fungus Gnat Traps for House Indoor, Fungus Traps Fruit Fly Traps for Indoors Gnats Sticky Traps for Plants Yellow Sticky Traps for Gnats - SUMMIT CHEMICAL CO 117-6 30OZ Mosquito Bits --- ## 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.dk/products/170089198-the-environmental-factor-nemaknights-slow-release-nematodes-280g](https://www.desertcart.dk/products/170089198-the-environmental-factor-nemaknights-slow-release-nematodes-280g) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-09-27*
