LOVE IT

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.

Pretty goid

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

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.
