Works great
I had ants coming from my ceiling area this year??? I tried everything, but, being in my kitchen everything dripped..yuck!!!! I got this because it was safer for my pets..has a nice even spay, and doesn't drip, like raid..the smell isn't great, but, didnt last too long..it did make the surfaces slippery..which I dont mind for a couple days, because its keeping the ants away. Im giving 5 stars because it worked great, price is good, smell is doable, well considering my other options, or ants in my food..

Actually smells nice
Smells like a heavily perfumed air freshener and not at all like a bug spray, at least none I've ever used. I bought my first can in the summer of 2024, my second a year later, and here I am with a third can in 2026. It dispenses easily and evenly and works quickly both indoors along the baseboards indoors and on ant hills and swarms outdoors. The smell can be a little overwhelming indoors so I make sure to air out the rooms where I use it. Even though it's marked as being made from natural ingredients that are pet safe, I isolate my cat away from the area of application for at least an hour, just in case.

Not a fan of the aerosol spray vs pump spray
Effective product, like their other similar products - BUT, do not like aerosol delivery. It spreads the product to areas I do not want it to and hangs in the air. I will go back to the pump version.

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.

Leaks
Leaks. Other than that, it works great. Natural ingredients. Safe and not too aromatic. Scent is lemongrass.

Worth it!
This worked great on ants. I haven't had a need for annother type of bug. Use it lightly the peppermint is strong. It's an inexpensive solution I only had to use once.

This stuff is awesome!!!
I had moved into an old apartment that was unfortunately infested with roaches. A funeral came by my house and told me oh there's no way that spray can work. I'd wait till one came out and spray them and let them watch it had a nervous breakdown and died. They squirm and they flip and they just don't know what to do. I don't want to be malicious but I don't like bugs, and the only reason I had bugs is because the next door neighbor was dirty. And nobody told me. So this stuff helped a lot.

very good
roaches really die with this. in 1 to 2 seconds for small ones. also they avoid where you spray. it is very oily but the scent is good
