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)

I went out of my way to write this review because this product is THAT magical. I was dealing with a fruit fly infestation that had lasted TWO MONTHS. They were coming up the drains from another apartment. They were horrific and relentless, even following me into my bedroom to swarm my face as I tried to sleep. I tried other sprays that worked... kind of. One with thymol, for instance. But it was aerosol and asphyxiating me when I sprayed it in the quantities needed to kill these wretched things.I got this stuff and I swear with two minutes, the infestation in my sink was *gone*. I have a few stragglers here and there hanging out in places where I can't safely spray, but the satisfaction of watching the vast majority of them die has made up for that.For its intended purpose, I have not found something better and that which will not leave you afraid of inhaling it. Now, it has a very strong smell. I don't find it pleasant, but it's not so bad that I won't use it. It's a lemongrass smell that's not quite so refreshing as lemongrass alone. It also leaves behind an oily residue. I knew it said "slippery", but this is... really oily. The bright side is that you can see exactly where you sprayed it and therefore need to wipe it up. Get some soap and a sponge and things will clean up.The smell and the oil are absolutely worth it to me because it has exterminated the infestation that was literally discouraging me from even going into my kitchen. I tried EVERYTHING that was safe for my cat before that. This is the only thing that's worked.10/10, recommend fully.

Affordable and Effective! I have a spider problem in my new apartment and it’s so annoying. They’re usually just on all 3 windows and I saw a huge one outside making the biggest web ever. I’m on a very high floor and didn’t think spiders would go up this far! I dusted the webs and spray this on all the window corners outside and inside. The spiders died within 10 seconds. I even noticed wasps avoid my windows now when they would usually tap my windows everyday. The smell is intense but not unbearable like chemicals. I opened all the windows and even the door to my apartment and I could smell it down the hallway on my floor. But it smells like a cleaning supply with an essential oil not as bad as the typical bug killers sprays. You probably don’t need as much as I used. Don’t over do it

I’ve been using this STEM spray in the kitchen and near doorways where ants like to sneak in, and overall, I’m pretty happy with it. It has a surprisingly pleasant scent — kind of minty and clean — which is a huge bonus compared to traditional bug sprays that smell harsh and chemical-y. I also like that it’s plant-based, especially since I have pets and didn’t want to use anything too harsh indoors.As for effectiveness, it definitely works, but it’s not instant. You need to spray it directly on the bugs, and even then it takes a little time to fully knock them out. For roaches, it sometimes took a couple extra sprays to really stop them. I wouldn’t call it a heavy-duty exterminator-type product, but for everyday use in the house or around outdoor furniture, it’s a solid option that feels safer to use around kids and pets.I’m giving it four stars instead of five only because it’s not as fast-acting as some conventional sprays. But I feel better using it in my home, and I’ll definitely buy it again.

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.
