Review: Does the job - Worked well no more flies
Review: 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!
