Pretty goid

anonymous June 10, 2025

I'm not gonna lie, the reviews kinda gave me a reason to believe this product wouldn't work, but it WORKED, you spray on contact, kills within a couple seconds, only thing is the smell kinda strong bothers me, but I'm not gonna complain cause it did its job also it is oily but it doesn't matter it worked

LOVE IT

Sara November 7, 2025

We've had a problem with pantry moths and tried numerous other products that were not effective nor safe. I tried STEM gnat and fly spray and it wiped them out! I sprayed once and resprayed the following day. I waited a week for any other eggs to hatch and sprayed again. Haven't seen them since.

This product works well on the bugs listed. It killed the gnats or drain flies on contact. The only problem that I had was spraying it in small or confined areas, it bothered my breath, but I do have COPD and I would recommend taking precautions ( open windows or wear a mask) when using.

Does not work, nozzle broken on arrival.

anonymous August 1, 2025

Arrived with broken tab top that would not budge, did not spray. Other one worked fine that I bought. Rather than return item I removed the plastic encasing, and put another spray nozzle on it from another type of product that was now empty! Easy fix! But seeing item nozzle is inconsistent, and first time buyer, I will not be buying it again. But also, it does not work. I stood outside and got gnats attacking me from the area seeing we had so much rain. I applied another company product, and no gnats….so it does not work to deter bugs from you or the area.

Not impressed with this purchase. Keep looking

Scot May 27, 2026

Retaining ring is difficult to remove and situated in a bad position. I'll need needle nose pliers to remove it so I can spray the product. Instructions say, Don't sray in the air, wait for the fly to land. Then spray for one second. Ever wait for flies or gnats to land? I can barely see them. As soon as you spray, they scatter in an instant. Spray for one second…really? Oh and you should be 18” away. Good luck sneaking up on them. I'd be better off with a plan old flyswatter.

It has a small ring around the neck that you must hold and twist with the spray top until it clicks into place that is open. Don't forget to shake it up. once spraying, it leaves an oily residue every where you sprayed and the oily residue always gets all over the outside of the spray can. If it is sprayed directly on the knat then that may kill it, but the knats will certainly be back within about 15 minutes.

Didn't do anything to flying gnats and flies. They fell down for about 15 seconds. Then started flying again. Not as advertised! I think a few of the flies were laughing at me or hiccuping from the odor. But non of the died after repeated spraying directly on them as stated in directions. Waste of time and money. Nozzle also leaks after locking nozzle and setting down in upright position for storage. Messy!

Foamed, spurted, and leaked all over my hand

Amanda June 6, 2025

This product leaked terribly the very first time I used it. It foamed, spurted, and leaked out from beneath the cap all over my hand. And I do mean all over my hand. The container looked normal when it was delivered - it was in the locked position and everything. There was nothing externally that hinted at a problem. It might be a fine product but I'm not buying it again because it was a deeply unpleasant experience; it made my skin sting terribly and the smell of the product lingered on my skin even after several minutes of hand washing and rinsing. And I can't even return it because...how? Leaking chemicals go into the trash, not back into the mail or into the hands of a store employee. Wear gloves the first time you use it, just in case. And maybe keep a plastic bag on hand.

This stuff is garbage!! It leaves oily residue everywhere you spray it at best it makes the flys oily but there was no change in them otherwise matter fact they were just as bad if not worse then before it …. I'm still wiping this junk off of cabinets
