Needed to also put gravel on the soil surface as part of a thirty day treatment plan Review: Gnats seem to enjoy a shower with this stuff! - I have been using this for several days, the fungus gnats don’t seem in the least bothered, even when sprayed direct. If anyone does want to try it, please note that the spray gun has a very small button at the bottom which you need to click to get it to work, then click back to close. It took ages to work this out! i am still catching tens of the things on sticky traps and in my window every day. I don’t feel this has done anything. The only good thing is it’s odour free. ## Features - Eradicate fungus gnats with our Fungus Gnat Killer Spray.

It works by targeting both adult gnats and larvae over time. For best results, apply consistently over several days to break the life cycle and prevent reinfestation. **Q: Is this safe for all houseplants?** A: Yes, the formula is designed to be safe for most houseplants, seedlings, and soil when used as directed. We recommend testing on a small area first, especially for delicate or sensitive plants. **Q: How often should I use the spray?** A: For active infestations, apply daily or every few days depending on severity. Continued use helps eliminate larvae in the soil and prevents new adults from emerging, ensuring longer-term control. **Q: Can I use this indoors without harming pets or people?** A: Yes, the eco-friendly formula is suitable for indoor use when applied as instructed. Avoid direct contact with pets and surfaces, and allow the spray to dry before letting pets near treated areas. **Q: Why am I still seeing gnats after spraying?** A: Fungus gnats have a life cycle, so you may still see adults shortly after treatment. This is normal. Continued application targets larvae in the soil, which is key to fully resolving the infestation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It’s early days but appears to work *by J***P on 2 June 2026* It seems to be working but time will tell. Needed to also put gravel on the soil surface as part of a thirty day treatment plan ### ⭐ Gnats seem to enjoy a shower with this stuff! *by L***8 on 3 September 2026* I have been using this for several days, the fungus gnats don’t seem in the least bothered, even when sprayed direct. If anyone does want to try it, please note that the spray gun has a very small button at the bottom which you need to click to get it to work, then click back to close. It took ages to work this out! i am still catching tens of the things on sticky traps and in my window every day. I don’t feel this has done anything. The only good thing is it’s odour free. ### ⭐⭐⭐⭐ Finally something that works *by R***L on 28 January 2025* After trying various compost toppings and sticky labels with little success i have found this spray made an immediate difference and no flies have emerged from the plants I have been treating. I missed one and after seeing a few flies for the first time in a week I realised the missed plant was the source. I am still using the sticky labels but highly recommend this spray. I do regularly spray the surface of the compost and find the small bottle lasts a suprisingly long time even though I think it is overpriced considering the ingredients. I have just bought a second and feel I will finally get rid of the scarid problem in my house plants that I've had for years. ## Frequently Bought Together - Fungus Gnat Killer Spray 200ml | Organic Protection Against Sciarid Flies | Effective for Houseplants, Seedlings | Safe for Indoor & Outdoor Use | Targets Adults & Larvae | Eco-Friendly Formula - aonova Fruit Fly Traps, Pack 30 Yellow Double-sided Fungus Gnat Sticky Catcher for Plants Indoor and Outdoor Insects Fly Control - Non-Toxic, Waterproof - Bloom & Bud Fungus Gnat Killer for Indoor Plants (1 Litre): Ultimate Indoor Plant Protector for No Gnat Pot Topping with Gravel Mulch Systemic Granules|Plant Gravel for Gravel for Indoor Pot Anti Gnat --- ## 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.tn/products/682217753-fungus-gnat-killer-spray-200ml-organic-protection-against-sciarid-flies](https://www.desertcart.tn/products/682217753-fungus-gnat-killer-spray-200ml-organic-protection-against-sciarid-flies) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-23*
