  • UPDATE: THE BEST INSECT/RODENT DETERRENT EVER! BUY IT AND PUT YOUR MIND AT EASE
Size: 12 Ounce (Pack of 1)
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. ... show more

  • Stem
Size: 12 Fl Oz (Pack of 3)
This product works really well. The smell isn’t that strong and I love That it’s plant base because it’s really safe for the dogs , but it kills ants, Roaches on the spot. And it is a oil base so it’s a little oily.

  • Effective, but with some draw backs
Size: 12 Ounce (Pack of 1)
This stuff does what it says it will do, but it has some draw backs. First it's oily/sticky and leaves a residue behind. Not a big deal if you don't need to spray cabinet shelving and countertops, but most people who have an ant problem need to do exactly that. Next is the odor. It's not wholely unpleasant, but it is entirely strong. First day of use we actually had to open up the windows because it was still incredibly strong after a few hours. Did it kill the ants? Yes. Did they stay gone? Of course not. It isn't designed for long term prevention, so if you need that, I'd suggest finding that elsewhere. This product is for short term maintenance. It kills *almost* on contact. The result is not "instant." At least, not on these Florida ants, but then, everything in this state seems to be a mutant with super powers lol Overall, for the price, if you just need to quickly kill off some intruding pests, this is a solid purchase. Just don't buy it expecting it to be a long term or permanent fix to your bug problem. ... show more

  • Effective, plant-based solution that actually works on fruit flies
Size: 12 Ounce (Pack of 1)
I recently dealt with a persistent fruit fly issue in my kitchen and decided to try this STEM botanical insecticide as a safer alternative to traditional bug sprays. I was incredibly impressed by how quickly it worked; after the first application, I noticed an immediate and significant decrease in activity. What sets this apart for me is the plant-based active ingredient. Because it’s used in a high-traffic area like the kitchen, I was relieved that it doesn't leave behind a harsh, lingering chemical odor. Instead, it has a much more manageable, botanical scent. The 12-oz bottle is easy to handle and provides a consistent spray. For the price, the value is excellent—it’s a reliable, effective product that I’ll definitely keep under the sink for future use." ... show more

  • Extermination of all flies
Size: 12 Ounce (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. ... show more
