  • 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

  • Whatever is in here it works.
Size: 12 Ounce (Pack of 1)
I bought Stem because of the reviews here, and I live in an apartment with a major roach problem. I normally rotate my poisons, and bait traps so my roaches can't adjust to the poisons I give them. STEM kills on contact and is effective for several days after spraying. I highly recommend this product to anyone who has a bug problem whether it's flies, roaches, and ants. The only downside is the smell. It can wake the dead and make your eyes water. Make sure you open your windows after spraying to prevent your eyes from watering. ... show more

  • 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

  • This Spray Works!
Size: 12 Ounce (Pack of 1)
I bought this product based on the reviews and really wasn't expecting much. I am using it on pesky flies that are outside and congregate near my door. It works! I sprayed it and flies were gone and they didn't come back for hours. Yes it has a strong essential oil smell. Never thought I'd write a review for a bug spray but this one is great. Safe for pets too which is a huge plus. ... show more

  • Works Great on Texas-Sized Roaches and Pesky Flies Works Great on Texas-Sized Roaches and Pesky Flies
Size: 12 Ounce (Pack of 1)
I bought the Stem Kills Ants, Roaches and Flies bug spray because Texas bugs do not know how to act right. Around here, a roach can walk in looking like it pays rent, and the flies will test every bit of patience the good Lord gave you. I have been using this spray for about a year now, and it has worked great for me. On smaller pests, it usually works right on contact. With those big Texas-sized roaches, sometimes one spray does the job, and sometimes I give them a second round just to make sure they understand the lease has been terminated. Either way, it handles them quickly without me having to chase the thing across the room like I am in some low-budget horror movie. It also works well on pesky flies, which is a blessing because flies seem to treat an open door like a personal invitation to come in and ruin everybody’s peace. I like keeping the bottle handy around entry areas, patios, and problem spots where bugs like to show up uninvited. I also appreciate that it uses a plant-based active ingredient. I still treat it like a bug spray and use it carefully, but I prefer it over the harsher-smelling sprays I have used before. The scent is noticeable, of course, but it is much more tolerable than traditional bug sprays. It sprays evenly and is easy to use. It can leave just a little bit of residue on surfaces, so I usually wipe the area afterward if I spray it indoors or somewhere visible. That is not a dealbreaker for me, but it is worth mentioning. Overall, I am very pleased with it. After a year of use, I still keep it around because it is effective, convenient, and strong enough for the kind of pests we deal with in Texas. Five stars from me, because any spray that can take down a roach with confidence deserves its stars. ... show more

  • The smell is not noxious or horrible...as other reviews would have you think.
Size: 12 Ounce (Pack of 1)
Just received so can only give an average review. However, I wanted to share my opinion re: the smell. It is not as bad as many reviewers would have you think. I am very sensitive to scents and was worried. Just received it, sprayed it in the problem crevices and it's not horrible. Based on some reviews, I was worried. Do not worry about the scent. Now, onto the oiliness...not an issue as I bought this for crevices I can't get to. I can only give this 3 stars as I have not seen lasting results, I only saw 2 ants die when spray hit them. (Fun serial killer stuff. lol) ... show more

  • Brutal to pests but stinks
Size: 12 Ounce (Pack of 1)
This stuff killed the mosquitoes in my apartment on contact. This chemical is brutal to pests. I would give it 5 stars for that alone but the smell. Mercy!! It is so bad I almost threw up. It is strong and, to me, smells like a chemical. I do not smell citrus at all. My pets seem unfazed by it, so it’s a good product to have on hand. It just stinks so bad. ... show more
