Review: Holy Gnat Nightmare! - Holy gnat nightmare! Our laundry room sink area was covered in gnats when we got back from vacation. There were even some of the little monsters flying around the house. We needed something safe for cats since they use this room. This worked like a charm and killed pretty immediately. Once its was dry it was safe for the cats but I still wiped it up after. Review: Pretty good. - As with the Stem light I got, it hasn't solved my drain fly infestation, but it's brought it somewhat under control. As I've seen others mention, this stuff does have a greasy sort of consistency. In fact, sometimes the flies it kills seem to die from getting trapped in the residue as much as what's in the spray. Be careful of the surfaces you spray it on. I generally hit windows, painted wood (like doors) or brick & such that won't generally be visible. I imagine it could stain wall paper or maybe even painted drywall or whatever. Not sure on that latter count. It has a strong but not unpleasant smell that either dissipates relatively quickly or I became nose-blind to quickly. ## Features - Bug spray that quickly kills flies, mosquitoes and gnats - Plant-based active ingredient bug killer safe for use around people and pets (when used as directed) - Entomologist tested bug spray made with botanical extracts to kill bugs; with fresh scent and no added dye, fragrance, or harsh chemical odors - Bug killer for indoor and outdoor use, wherever bugs try to bother you? - Rooted in Nature, Optimized by Science ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09GD28ZS1 | | Active Ingredients | Active Ingredients: Geraniol (1.47%), Lemongrass Oil (0.10%) | | Best Sellers Rank | #434 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #34 in Insect & Pest Repellent Sprays | | Brand | STEM | | Brand Name | STEM | | Customer Reviews | 4.0 out of 5 stars 5,130 Reviews | | Global Trade Identification Number | 00046500032813 | | Included Components | Spray | | Item Form | Aerosol | | Item Weight | 10 ounces | | Liquid Volume | 10 fluid ounces | | Manufacturer | SC Johnson | | Model Number | 3281 | | Part Number | 3281 | | Specification Met | Entomologist Tested | | Target Species | Insects | | UPC | 046500032813 | | Unit Count | 10 Ounce | ## Product Details - **Active Ingredients:** Active Ingredients: Geraniol (1.47%), Lemongrass Oil (0.10%) - **Brand:** STEM - **Item Form:** Aerosol - **Item Weight:** 10 ounces - **Liquid Volume:** 10 fluid ounces ## Images ![STEM Plant-Based Bug Spray, Insect Killer Indoor Outdoor, 10 fl oz | Botanical Insecticide, Kills Flies, Mosquitoes, Gnats, Indoor and Outdoor Use, Plant-Based Active, Non-Toxic Formula - Image 1](https://m.media-amazon.com/images/I/61QcNEdn0FL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Holy Gnat Nightmare! *by J***K on August 16, 2026* Holy gnat nightmare! Our laundry room sink area was covered in gnats when we got back from vacation. There were even some of the little monsters flying around the house. We needed something safe for cats since they use this room. This worked like a charm and killed pretty immediately. Once its was dry it was safe for the cats but I still wiped it up after. ### ⭐⭐⭐⭐⭐ Pretty good. *by M***E on September 7, 2024* As with the Stem light I got, it hasn't solved my drain fly infestation, but it's brought it somewhat under control. As I've seen others mention, this stuff does have a greasy sort of consistency. In fact, sometimes the flies it kills seem to die from getting trapped in the residue as much as what's in the spray. Be careful of the surfaces you spray it on. I generally hit windows, painted wood (like doors) or brick & such that won't generally be visible. I imagine it could stain wall paper or maybe even painted drywall or whatever. Not sure on that latter count. It has a strong but not unpleasant smell that either dissipates relatively quickly or I became nose-blind to quickly. ### ⭐⭐⭐⭐ It works! *by M***N on September 7, 2025* This product does work pretty well. 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.ma/products/397054377-stem-plant-based-bug-spray-insect-killer-indoor-outdoor-10](https://www.desertcart.ma/products/397054377-stem-plant-based-bug-spray-insect-killer-indoor-outdoor-10) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-08-21*
