millerman543started grow question 2y ago
I’ve had a serious fungus gnat problem and I can not get them to go away I’ve tried the beneficial bacteria and I’ve tried dunking the pots in organic pesticide bucket and they still persist. How can I get rid of these mfs???

It takes a pretty bad infestation to actually affect your plants. The flies are harmless but the larvae can damage roots in large numbers. The best defense against them is not promoting an environment they like. Don't keep the top of your soil wet all the time. Maybe try bottom feeding until you get them under control. You can top dress your soil with diatomaceous earth . It's food grade and kills both gnats and larvae on contract.

Gnats occur when the soil is constantly too wet. Letting your soil dry out more between irrigations would help. Hydrogen peroxide may help, as would Aza Max/Neem oil.
