    • UPDATE: THE BEST INSECT/RODENT DETERRENT EVER! BUY IT AND PUT YOUR MIND AT EASE
Size: 12 Fl Oz (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

    • It works like magic!
Size: 12 Fl Oz (Pack of 1)
WOW! This works like magic! I have ants that like to colonize inside my beloved books on the shelf that acts as the headboard to my bed! Two or three sprays with this product, and the ants died instantly. The ants did not revive, and new ants have not returned. In the kitchen, I can set out a little piece of juicy fruit in the sink, and when fruit flies are crawling over it by the hoards, one spray will kill thousands! This time of year (summer & fall), we have fruit pieces landing in our trash, so of course the fruit flies follow. Lifting the lid of the trash can bring on a swarm of fruit flies in the face. But two sprays in the can, close the lid, and no more flies in the face when opening the trash lid. This product suggests not spraying flies in the air. But once they land, they don't have a chance if I am nearby holding my bottle of STEM spray. I really am happy with this product and I keep a bottle in my bedroom, bathroom, and kitchen. The smell is tolerable to me, especially knowing it is non-toxic. And it dissipates anyway after a while. I highly recommend this product. ... show more

    • Works great, but stinks!
Size: 12 Fl Oz (Pack of 1)
This insect killer is very reliable and will destroy unwanted bugs in the house. It works great. I've used it on annoying flies and some other bothersome summer insects and have always had success. I'd definitely recommend it for anyone dealing with unpleasant insects, especially families with kids and pets. ✓ Safe and non-toxic. The active ingredient is derived from geraniums. It isn't poisonous to kids or pets. ✓ Highly effective. It works instantly. ✓ The sprayer works reliably and makes it easy to target the insect. ✕ The smell is extremely strong and quite unpleasant. It is overwhelmingly floral in a very cloying way and lasts for days after a single spray. ✕ A family member did have difficulty breathing after this product was used indoors. We needed to air the place out a bit before she could come back in. ✕ It leaves an oily residue on surfaces that is difficult to remove from fabrics. So far no staining, but the greasy spots it left on the walls were hard to clean up. Based on my experiences, I now use this product outdoors only. I'd recommend it for outdoor use, but indoors find something else. ... show more

    • Kills and repelled those nasty mosquitos!
Size: 12 Fl Oz (Pack of 1)
STEM has an amazing fresh smell. Worked on some mosquito issues I have in the evenings! I highly recommend this product. Just don't spray it on windows as it may leave a little oil behind but can clean up easy with window cleaner. My dogs are safe with it too! They are very sensitive, and they are fine with it. I haven't had a spider around in a while since using it, so it seems to repel a lot of different creepy crawlers. ... show more
