STEM Kills Indoor and Outdoor Flies Mosquitoes and Gnats Insect Killer Bug Spray, 10 oz

I am so torn in regards to a rating for this product since I both love it and hate it. To begin with, it really is one of the ONLY products that actually kills gnats on contact like a lot of products say they do, but don't. With other products (and we have tried so many) those horrible gnats just laugh and keep flying around. This STEM spray stops them dead in their tracks. That said, the oily film this spray leaves behind is almost as awful as the gnats themselves, and I am not exaggerating. No matter how little you try to spray, it looks as if you've spilled oil all over the place. If you have hardwood floors, it is just untenable. Also, we have four dogs and we literally had to close off the area for DAYS even though we threw towels on the floor because we really don't trust it to be safe for them seeing as the stuff won't dry on its own! Yes, gnats are probably (as we have found) one of the worst issues to deal with, and when dealing with such a pest problem you think there's nothing you won't go through to get rid of them. Unfortunately, the sopping mess this spray leaves behind is just a step too far. I simply cannot stress how much oily residue this spray leaves behind and therefore, just cannot recommend it.

this is an oil based product and if it is on the floor watch your step. my son fell because he slid on its oily residue it left behind. the smell is awful. i feel that in order to kill the flies i had to spray them direct contact. spend the extra dollar or two and get a product that works without the threat of injury .
