Does what it says, and that's kill gnats. We had a significant amount get into our kitchen recently, likely trying to escape the coming cold, and this made short work of them. The only reason I wouldn't give it 5 stars is the smell is less than pleasant and it leaves behind a greasy residue.

Olivia - 6 months ago, Verified purchaser
smells terrible (I'm not sensitive to smells). i don't have much opportunity to spray them bc it says to wait until they've landed on a surface, so unless i spray directly onto my fruit, they're usually flying around. and it says to oversaturate them so again the smell is just too much. onto the next.
1 reply from stem Team team - 5 months ago
Thanks for taking the time to reach out, Olivia. Because STEM Flies, Mosquitoes & Gnats is made up of essential oils, this spray has a stronger aroma. After use, the fragrance typically fades away within a few hours; if sprayed heavily, it may last longer. To quickly eliminate the scent, be sure to ventilate the area and clean surfaces with warm, soapy water. So we can help with this, please give us a call weekdays from 8 a.m. to 5 p.m. CT at 877-869-7546 and provide your reference number: 22680696. We look forward to hearing from you! – Mindi, STEM Consumer Care

The smell and residue are more lethal than the product on flying insects
1 reply from stem Team team - 7 months ago
Thanks for reaching out, and I'm sorry to hear this. Due to the essential oils in this product, it tends to leave an oily residue. That's why we only advise directly spraying the insects, as directed on the back label, and cleaning away excess spray after use. The fragrance usually disappears within a few hours; if sprayed heavily, it may last longer. Make sure to ventilate the space and wash any surfaces with warm, soapy water to quickly get rid of the smell. Call us weekdays from 8 a.m. to 5 p.m. CT at 877-869-7546 and provide this reference number: 22625998. We can't wait to chat! – Mindi, STEM Consumer Care

It kills the gnats right away, they do fall where ever they are so be prepared to spray and wipe wherever they are. Also the smell is not strong if you have little ones at home it’s okay for them to be around.

Works great! My neighbor has chickens and I keep a covered dog poop bucket on far end of yard by his fence and we get tons of flies. Sprayed some of this on poop bucket and fence I share with neighbor and there are significantly less flies. I’ve only see a couple since then. Well worth the money! And kid and pet friendly!

Kills gnats if spayed directly on them. Watch where you spray because it is greasy. I ended up with oily residue on my countertops and cabinets. Smells like Deep Woods Off bug spray.

I sprayed the window sills. A few days later there were hundreds of dead knats all over the sprayed area. Works fantastic ! Where I live ( Az ) the heat brings them out at night. This is the best product ever I contacted a local exterminator and they had no answer for my problem STEM did the job and I will buy as long as I live here.

This products does not work and its super messy, greasy and I still have GNATS. Even when I used t in my garage the ground had so much oil from this spray it was a mess.
1 reply from stempwr team - 10 months ago
We appreciate you letting us know what happened, and we too would expect this to take care of those gnats. Since STEM® Flies, Mosquitoes, & Gnats Spray contains essential oils, we don't recommend using them on floors. However, any oily residue should easily come clean with warm, soapy water. Call 1-800-558-5252 (weekdays, 8 a.m. to 5 p.m. CT) and include your reference number, 22511150, if we can be of more assistance. We hope to hear from you soon! - Mindi, SC Johnson Consumer Care

I can't get any action from the plastic cap. It will not depress to spray as the instructions describe and I'm sure I'm not supposed to pull it off in order to use. What's going on? This shouldn't be difficult!
1 reply from stempwr team - 10 months ago
We're sorry to hear you're struggling with this, Jack! To open the STEM® Flies, Mosquitoes, & Gnats Spray, you must unlock the spray function by moving the nozzle to the "open" icon, which is located below the spray nozzle and printed in the clear plastic. If we can be of any more help, please give us a call at 877-869-7546 and provide reference number 22508346. I hope this helps! - Mindi, SC Johnson Consumer Care

bamabeth3240 - 11 months ago
I am seeing little gnats around my home and thought this would be a great solution for me. I think it works just OK… I think the oiliness prevents them from flying and eventually they will die. But the amount of oil in this product is an issue. I sprayed my countertops, trying to get some gnats that were flying around in my bathroom and even though I thought I had cleaned out the oil residue the next morning I sat my coffee cup down on the Vanity counter and picked it up and for some reason, put it against my brand new sweatshirt and there was a ring of oil left. Hopefully I can salvage the brand new gray sweatshirt.

I really hate flies. Where we live there's numerous kinds from tiny black flies to those nasty jumbo ones. We have Frenchies that are elderly so we abstain from using any kind of poison. Broke down and tried STEM it works wonderfully. Kills on contact.(yay) Great smell from lemongrass and easy to wipe up any excess. Will buy again and again. Thank you for great product.

Compared to Zevo it sprays really well. But the mist release is so oily and heavily concentrated not sure it’s worth the hassle. Oil residue is all over my floor and countertops. I almost slipped twice while cleaning up.

I love the fact that it kills flies and gnats on contact, however as they fly i seem to have to spray them midflight, there is an oily residue that drips EVERYWHERE. So I end up cleaning the whole room again and again. I wish they could make it as effective without the mess.

Not sure why there isn't a warning in bold type but this spray will stain your painted walls. My condo now has a ton of stains all over several walls because I didn't realize this before buying. Now, in addition to getting rid of these gnats, I have to figure out how to fix all my walls. There are better options!

Wow, this stuff works but be careful where you spray it because oil gets everywhere. I’m assuming they use a lot of essential oil in this. My carpet ended up being very slippery.
