    • 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

    • Amazing product
Scent: Unscented Size: 12 Fl Oz
The Stem spray is great at handling ants, roaches, and flies, thanks to its plant-based active ingredients. It is safe for both indoor and outdoor use, has no strong odor, and works quickly. The convenient packaging and effective formula provide pest control without chemicals.

    • Best purchase for summer
Scent: Unscented Size: 12 Fl Oz
Where I live the ants and other bugs easily make themselves at home in my apartment. The ants were AGGRESSIVE. My apartment complex had just sprayed a few days prior and it just wasn’t cutting it. The scent is STRONG but it works!!! It works inside and outside for me. For outside if it rains it’s good to spray again after it dries up a bit. But inside let the air flow a little to circulate the strong smell. I love it because it’s safe to use around my cats. Definitely kills on contact. Haven’t tried it on spiders yet. But I will be! Have those outside my windows. It does also leave some oil behind but I just take some paper towels and dab up the severe excess. The reason it lost one start in the review is because of the strong smell. Otherwise it’s perfect. ... 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

    • Fast and easy
Scent: Unscented Size: 12 Fl Oz
This is the perfect spray for German roaches and quickly eliminates them when sprayed directly. Arrived without any leaks. The only problem was that the spray trigger stopped working

Scent: Unscented Size: 12 Fl Oz
Very effective and safe to use inside the house.Good value for the money.So many dead ants in the bathroom corner. I think I still have to treat outside to completely control it.
