Q: seriously, how do you open it?
submitted by marisa - 1 year ago
A: Ignore STEM rep answer, "clear plastic" referenced is actually the bottom part of the sprayer and doesn't come off. You have to break the top from the bottom, twisting like a bottle cap. Then turn top
submitted byJackie - 6 months agoA: We're sorry for any troubles experienced while using our STEM Flies, Mosquitoes, & Gnats. To begin use of this product, first you must remove the clear plastic located below the spray nozzle. Once this is removed, the sprayer must be turned to the "open" icon and spraying can begin! For any further assistance, please contact us at 877-869-7546 (weekdays, 8 a.m. – 5 p.m. CT). Hope this helps! – Megan, STEM Consumer Care

SLIPPERY BUG SPRAY
This spray made the floor very greasy where you sprayed to the point I had to mop it up to keep from slipping down.
1 reply from stem Team team - 3 months ago
Thanks so much for reaching out! STEM Flies, Mosquitoes & Gnats contains essential oils, which can sometimes leave a bit of an oily residue. That’s why we recommend spraying it directly on insects only, as directed on the back label, and wiping away any excess after use. We'd appreciate the chance to chat and assist you further. Give us a call at 877-869-7546 (weekdays, 8 a.m. to 5 p.m. CT), and have your reference number 22913143 handy. We’re here to help and can't wait to get you back to bug–free! – Megan, STEM Consumer Care

Good product
It works very well but when you spray it, it gets all over the spray bottle and your hand. The floor also gets very slippery with it.

Killed the flies, left stubborn residue
If you have an infestation like I did from my son. Leaving a banana In his bathroom for a week it's worth it. It kills them on contact and got rid of The literal swarm in his bathroom be very careful. The spray goes far and is very hard to get off of surfaces especially mirrors. It's very slick and it smells slightly off-putting but not unbearable. If you only have a few just smack them but this is definitely worth it in emergencies. It will work immediately but you'll have to clean up.

This stuff is magical! I love that it is safe so I don’t have to be paranoid about having poison sprayed around the house. It says not to spray in the air, but I’ve had to do that for pesky flies and they literally just drop. This spray works faster to incapacitate bugs than wasp spray!

Knats problem in hot summertime
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.

WASTE OF MONEY AND MESSY
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 - 1 year 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

Believe it or not, trouble operating the bottle!
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 - 1 year 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

Great product
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.

Works great, less mess please
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.

THE ONLY THING THAT WORKS
This is the only product that will kill German cockroaches, Ides, the pest control I saw them die instantly in front of me. When they walked right into it I was a little surprised to see the other review, and the guy said it doesn't work. It works amazing and the fact that it's plant-based, and safe for kids and animals makes me very happy you have a customer for life I don't say this lately good job and putting this together smart people

Used it for flies and the flies laughed at me! Seriously it didn't kill one fly. Disappointing.

We're so sorry to hear this didn't do the trick, Val. As long as you're spraying the flies directly, we'd expect them to die on contact.

The dark corner of my patio where I stack the chairs became home to mosquitoes as temps have dropped. We couldn't go out and get a chair and enjoy the fall weather. Now dead. Smells good, too.

Mosquitos Beware
[This review was collected as part of a promotion.] This is the first time I'm hearing about this brand and I'm sure glad I did. I like that it's a natural formula that is safe to use around kids and pets because I have both. The bottle looks nice and sprays lightly and evenly. I used it a few times for gnats and mosquitos and it worked great.
