Review: I love this stuff - I have a problem with roaches, and, seasonally, ants. Though I am a vegan and try not to kill anything, I just have to make some exceptions. This stuff kills on contact! It is oily, and when I can, I just leave it there because it will continue to kill or repel the insects. I particularly love that it is nontoxic. And it is very reasonably priced. I am a customer for life.
Review: Dead ant dead ant, dead ant. - I purchased this product a year ago and while it did work, I really didn't put it to the test until this year. I noticed a small ant crawling across my kitchen countertop. Each day there were a few more ants and by about the fifth day there was a trail of ants coming out of the light switch above of the counter. That's when I remembered I had some Stem and I sprayed around the outside of the light switch and into a small crack where the backsplash meets the countertop. I think the smell is horrendous. It isn't as bad as Raid but if Raid and a plant had a baby is the best way I can describe it. The smell is very strong and lasts for a long time - I can actually taste it. When I wiped the excess it was slightly oily. With the window open and a fan on, it dissipated after a few days. From the time I sprayed, over the next few days I still saw random ants limping across the countertop. Less every day but I didn't think the spray worked so I ordered ant traps. By the time the ant traps were delivered (2 days later), there are no more ants! I truly can't believe it. I didn't want to put ant traps in my kitchen and have a hundred ants crawling around the trap for days but I know I needed to kill the colony and the queen. I didn't use the ant traps. Just a few shots of Stem - not even directly on the source - and within about 4 or 5 days there are no more ants! Did they take the poison back to the colony, who knows. All I know is those suckers are gone and I haven't seen one in over a week. I had to find this product in my old orders just to write a review because it is that good! Just be patient and give it a few days to completely do the job.

### ⭐⭐⭐⭐ works well, smells good
*by E***N on December 14, 2025*

We've used this a few times in the apartment for roaches, spiders, and ants (great luck, I know lol), and it's worked well! My boyfriend actually really likes the smell of it. I think it's pleasant too, especially compared to regular bug spray. I have 2 cats, and I will only ever buy very safe products that explicitly mention they are pet and family-safe. Sometimes this means they don't work as well or are much more expensive because the natural ingredients - this product is not one of those, and neither is the STEM brand overall. The spray works well and hasn't been uneven. The only con I have about this product, which I experienced with another STEM product, is that there is like a slight oily residue after you spray it that requires (at least in my experiences) more than just a dry paper towel to remove. It doesn't necessarily feel oily if you just dry wipe it, but you can tell it feels and looks a little slick (for lack of a better term lol). In the light, you can definitely see the area it was sprayed if you don't use a cleaner after. I use Lysol multipurpose spray, and it removes it fine. Dawn Powerwash worked too. A little annoying, but the pros outweigh the cons, so if we ever need more bug spray, I'll be repurchasing.
