I've had drain flies come every summer and stay until winter. They drive me crazy! I didn't want to spray a strong, caustic, poison in my bedroom (they were everywhere!) where there's no windows or ventilation whatsoever. So I thought I'd try this and I am not sorry. It says to not spray it in the air and to wait for the insect to land, then spray the insect. I just sprayed my whole room anyway and it worked great there was only 1 tiny one flying around for the next few days, it was great! I've only had to spray it twice (the 2nd time was directly at one I saw). I'm not crazy about the smell, but it's a lot better than the strong chemical smell that would come with Raid or one of those products. It's that lemongrass smell. I only have 2 small issues with this product. #1 the trigger/sprayer. I actually like it because it's easy to use, but it's too easy is the problem. You're meant to push the trigger with your thumb, not pull the trigger with your index finger. Well, my genius self, didn't actually look to make sure it was pointed in the right direction and tried squeezing the trigger (like a can of Febreze). I sprayed myself directly in the forehead and top of my head. Thankfully I had the can tipped and didn't get my eyes, just my freshly washed, still damp, hair. So make sure you know what way the nozzle is loi ting before you spray. Push the button with your thumb, NOT your index finger. #2- all the oil everywhere! I sprayed the air in my kitchen and then almost bust my ass! The floor was so slick! I had to mop the entire floor with hot water and dawn dish soap. The directions DO say toward for the insect to land, spray it for at least a second, then use soap & water to clean the area. This is turning into a lot of work, just to kill a few drain flies. I do feel better knowing that im using a non toxic, safe for humans & pets, product. Overall, I'm happy with the results. ## Frequently Bought Together - STEM Kills Flies, Mosquitoes And Gnats: Plant-Based Active Ingredient Bug Spray, Botanical Insecticide For Indoor And Outdoor Use; 10 fl oz (Pack Of 1) - STEM Kills Ants, Roaches And Flies: Plant-Based Active Ingredient Bug Spray, Botanical Insecticide For Indoor And Outdoor Use; 12 fl oz (Pack Of 1) - STEM Kills Ants, Roaches And Spiders: Plant-Based Active Ingredient Bug Spray, Botanical Insecticide For Indoor And Outdoor Use; 10 fl oz (Pack Of 1) --- ## 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.ro/products/397054377-plant-based-bug-spray-insect-killer-indoor-outdoor-10-fl](https://www.desertcart.ro/products/397054377-plant-based-bug-spray-insect-killer-indoor-outdoor-10-fl) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-27*
