There where flying ants EVERYWHERE. All over my bed, me. I cannot even. I got this product because I have cats and I thought I'd take a chance on something natural that wouldn't hurt them before I went all out with the poison and honestly, this stuff was awesome. I haven't had any more issues since I've started using this. I sprayed it all outside and inside and unlike most of the natural 'safe for pets' it doesn't have that god awful smell that leaves you with a headache. It's got a bit of a minty smell but it's not unpleasant at all. Doesn't seem to bother my cats either and most importantly, it seems like it kills ants on contact. My vacuum is like an ant graveyard now. ### ⭐⭐⭐⭐⭐ UPDATE: THE BEST INSECT/RODENT DETERRENT EVER! BUY IT AND PUT YOUR MIND AT EASE *by on Reviewed in the United States March 20, 2025* I'm updating my review: I LOVE THIS STUFF AND NOTHING ELSE WORKS LIKE IT. It's easy. As mentioned below they state STEM may need reapplication, but not that often. And, a little goes a long long way. Plus, because the price is right, you can continue to purchase it as you need it. Critters really hate it and go away. It is so worth it. If you spray them they die immediately but I don't care if they die. I just want them to stay away and they do! The smell is overwhelming and I don't care! The scent alone DETERS anything from insects to rodents. It keeps me from having to set traps. It keeps me from using neurotoxin sprays. I love it and wish it didn't smell so strong but THAT'S WHY IT WORKS!!! It's only essential oils and it is all natural.After the third yellow sac spider (and he seemed well-fed) landed in my bed, I had - had enough. I give a quick SPURT anywhere I might see a cobweb or in corners and on the ceiling fan ...because they seem to like it up there, dopes. Regardless, the smell alone is a deterrent! Wouldn't it be nice if you didn't see them at all! Wouldn't it be nice if they just stayed away? I don't mind reapplication because it doesn't take much. A SPRITZ DOES THE TRICK. Thankfully the price is right or I would look into other options but the lemongrass in this product is despised by spiders and rodents. A small spritz and your whole room will be a deterrent. I would now like to get some sleep and think I will. I don't like seeing creatures and I don't want them around. This keeps them away in the first place! Isn't that what you want? Don't hesitate. Don't bother with ant traps. Use this and repeat the usage until it stops. You can use traps outside the house, if you have more trouble. It does leave a horribly oily residue so don't spray it anywhere you can't wipe down later. That's the only drawback and it's not a big one.Despite the fact that this may need reapplication, it's surprising how well it works. I had to leave one of the homes unoccupied for quite a while (years). I bought this for ants, but was surprised to find that some mice had also taken up residence in the basement. I would spray and although the scent would dissipate, it actually took some time... Longer than they say on the bottle. I also found wetting cardboard, cotton balls or anything absorbent could be placed in various locations and that makes for easy cleanup. I'd simply spray again, and eventually, it seemed they did not want to come back. As far as the ants go, they are dead on contact. All I needed to do was find the general location where they were coming from and it was over. One small word of caution, if you are sensitive to smells, you won't get away scott-free. It may be natural but a little goes a long way. Overspraying, was overwhelming. It gave me headaches. IT WAS STILL WORTH IT! Don't overspray. ### ⭐⭐⭐⭐ Kills ants on contact *by on Reviewed in the United States August 7, 2026* It works very well. We had some ants that turned up out of the blue and this stopped them immediately. We have cats so it had to be non toxic. The smell is a bit strong but not a bad smell. Be aware that is oily and slippery. You will need to wipe it off or you can easily go sliding across the floor. Luckily it works pretty much on contact so you can wipe it off within a short period of time. ## Frequently Bought Together - 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) - TERRO Ant Killer Bait Stations T300B - Liquid Bait to Eliminate Ants - 12 Count Stations for Effective Indoor Ant Control - Raid Ant Killer Baits, Child Resistant Bug Killer for Indoor Home Use, 0.24 Oz, 8 Count --- ## 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/395207571-kills-ants-roaches-and-flies-plant-based-active-ingredient-bug](https://www.desertcart.co.th/products/395207571-kills-ants-roaches-and-flies-plant-based-active-ingredient-bug) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-15*
