    • This actually works (on earwigs too!)
Scent: Unscented Size: 12 Fl Oz
I don't know what happened this year, but suddenly my house was the meeting point for every earwig in the neighborhood. I mean, they were crawling on my screen door in waves, if you picked up anything outside at night, there was a mat of them - there were literally so many crawling on my hosta stalks that they were bending over. It was gross. Some even made their way into my basement window wells and got in the window down there. Absolutely not. I've tried a few ant killers here and there before, they usually smell foul, don't really last, and are expensive. This product was none of that. It does have a smell, but it's not that strong or awful. It lasted about 4-7 days per application around my sliding doors and the window wells. Obviously it lasted a bit longer with inside application than outside, but the fact that it lasted outside at all is high praise against other products that do not at all. It also seems to kill both ants and earwigs on contact as well as repel them (I live in the woods with a high humidity level, so we get roaming carpenter ants too, and this worked on them as well). It's a bit oily, but I didn't have any issues with it staining bricks, stone, or the white painted trim I put it on outside. It sprays very fine, so it doesn't take a ton to cover a decent area. Also, my dogs and cat had no issue with it, which is great. Since I was spraying it liberally on the threshold where they do into and out of the yard, they came in contact with it to some degree, and they had no issues with it. They didn't even sniff at it. I have a degree in Chemical Engineering, so I'm definitely not one of those "omg chemicals are bad!" people that avoids all pesticide or only buys "natural" things, but I bought this on a whim on sale and highly recommend it. Works AT LEAST as good as standard commercial ant killers like Raid for sure. I will 100% be buying it again next year. ... show more

    • Interesting smell
Scent: Unscented Size: 12 Fl Oz
Has a very unique smell. It's not bad, but if you're sensitive I'd use caution if you're using a lot of product at once. The ingredients are safe around my pups which is a huge plus. Especially since the biggest issue we have is ants in the kitchen every summer. Laying this down as a barrier around the doors and baseboards has helped tremendously. ... show more

    • Almost the Perfect Product!
Scent: Unscented Size: 12 Fl Oz
### STEM Ant Killer Review STEM Ant Killer is a game-changer in the world of natural pest control. As someone who is cautious about the chemicals used around my home, especially with kids and pets, finding an effective and safe ant killer has been a challenge. STEM Ant Killer exceeds expectations in both efficacy and safety, making it a near-perfect product. From the moment you spray, you can see the powerful botanical-based formula in action. It not only eradicates ants quickly but also prevents them from coming back, providing long-lasting protection. The peace of mind that comes with knowing the product is derived from natural ingredients is unparalleled. Unlike other natural ant killers that often require multiple applications and still leave doubts about their effectiveness, STEM delivers consistent and reliable results. The convenience of use is another major highlight. The nozzle design allows for precise application, ensuring you target only the areas needed without excess spray. This makes it particularly handy for indoor use, avoiding unnecessary exposure to surfaces that come into contact with family members. While STEM Ant Killer is already an outstanding product, it could reach perfection with a minor enhancement: a capture chamber connected to the nozzle for overhead use. This addition would set it apart from all other natural ant killers on the market. Imagine effortlessly targeting hard-to-reach spots like ceiling corners or high shelves where ants often travel, without the mess or risk of dripping. Such a feature would not only enhance usability but also ensure even more comprehensive coverage, leaving no place for ants to hide. In summary, STEM Ant Killer is almost the perfect solution for anyone seeking a safe, effective, and natural way to manage ant problems. Its potent formula and ease of use make it a standout product. With the potential addition of an overhead capture chamber, it would undoubtedly become the superior choice in natural pest control, unmatched by any competitor. ... show more

    • Best bug killer ever!
Scent: Unscented Size: 12 Fl Oz
I bought this as I don’t like spraying poisonous bug killers IN or outside my home. I used this outside my kitchen patio door, & outside my front entrance. I sprayed some on the door threshold… low & behold, I haven’t seen ANY bugs in or outside. It has an organic smell but I don’t mind it but apparently BUGS HATE THE NATURAL OILS it’s made with!!! Hooray! I have in on subscription as it works without poison!👍👍👍👍👍👍👍 ... show more

    • Extremely powerful, yet natural and safe!
Scent: Unscented Size: 12 Fl Oz
This not only kills insects like ants and fruit flies on contact, it repels them for what seems like months before another application is required! I recommend spraying along your baseboards, doors, and windows. This creates a lasting "barrier" that deters most bugs. Super worth it, and non-toxic to me and my dog! ... show more

    • It works!
Scent: Unscented Size: 12 Fl Oz
This product kills ants on contact. It is safe for kids and pets. However, it is lemongrass OIL. Do not use on floors or counters. It will make them oily and slippery. Everything will be a greasy mess. It also does not prevent the ants from coning back. Better off using Borax. I do not recommend

    • Indoor Use, Ok around pets and people, Botanical Based Insecticide
Scent: Unscented Size: 12 Fl Oz
This product works perfectly for knocking down indoor cagy flies that normally are quite difficult to take down just 2-3 with a normal or electric fly swatter. A small mist on them and they hit the ground, unable to fly and die on the ground later or become spider food. Good value, results and safer to use than using a pesticide spray that normally you'd definitely only use outdoors. ... show more
