If you get fungus gnats you can just cover your medium with steel wool. The gnats trying to get to your medium will get shredded as will any new ones being born out of the medium. After around 2 weeks they will be gone.
Hey Doug sorry to necro an old post but I’m new and can’t figure out how to message you. Anyways does this steel wool trick really work? I never heard of it. I was thinking of using sand, I just used some AzaMax today in the soil during transplant but probably applied it too lightly.
No worries. So I have never had fungus gnats but everything I read says it works well. Here is a link to a pest company that recommends it, seems to me that is a pretty good indication it works or a professional pest company wouldn't put it on their site. You can Google steel wool for fungus gnats to find all sorts of other information as well. Best of luck with your problem, hope you get them under control.
