Review: Really works and doesn't smell bad! - I just moved into my new house and I woke up to a scene out of a horror movie. 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.
Review: UPDATE: THE BEST INSECT/RODENT DETERRENT EVER! BUY IT AND PUT YOUR MIND AT EASE - 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.

### ⭐⭐⭐⭐ Isn’t as effective as advertised
*by T***E on August 1, 2026*

The spray is good. It does somewhat of the job, but it’s not really as great as I thought it would be. I mean, it helped to keep some of the fruit flies in my house gone but there’s still a lot on there. It doesn’t smell bad though, and it is safe to use with having my cat. That’s definitely a plus cause I always try to get something that is not going to harm my cat and it has a label and says it is safe to use when you have animals
