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.
Review: Works better than the rest - I had a pretty extensive fly infestation after bringing my outside plants inside for the winter. This product not only did everything it says, but smells great. It leaves a slight oil film on a surface but easy to clean up, it also smells fantastic. A little goes a long way. Pet friendly under supervision, I have 3 dogs and 4 rabbits and just ventilated the room (with a screened window) and avoided their beds, etc. I’m purchasing a second bottle for a backup!

### ⭐⭐⭐⭐ Effective, but with some draw backs
*by E***. on December 16, 2025*

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.
