Good size bottle. Seems to be working
Good size spray bottle, bigger than others I've had. Just hoping it works as last summer I was inundated with these blessed gnats. I've been using it and not seen any more dead gnats appearing which is a good sign. Think they have a cycle of 28 days so need to continue using as a break in spraying will allow them to hatch and the process starts again. Not the cheapest spray I've had but the bottle size is bigger

Don't bother - it doesn't work
Everywhere I go in my house I see tiny black flies. As soon as I sit down they come looking for me and annoy me by flying around in front of my eyes. When I go to swat them they disappear, only to reappear a few moments later! I bought this Fungus Gnat Killer and used it as per the instructions. However, it has made not a ha'porth of difference. We still have flies. They are obviously coming from the compost I bought to repot a Peace Lily plant that had outgrown its pot. It was so big I split it into two plants so have twice the number of flies I would have had if I'd just repotted it as one plant! I put yellow bug catcher stickies in all of my plants which, as you can see, have been very effective. The photos show both sides of the two stickies I put in the worst affected plant just a week ago!

Not sure it is working
I had infestation in 6 plants....3 are still infested despite using. For the price it is a bit of a gamble. I am also trying alternative methods - I think to soluble tablets might work better

Recommended.
This worked great. Sprayed around the soil of my chilli plants and then watered so it got deeper down with the water. It definitely worked, I do not see any midges any more around my plants or house. There was no smell and has not effected my plants. I didnt spray much either. I definitely recommend this one.
