Hi everyone, I have never had any encounters where plants are negatively affected by fungus gnats. From what I understand, they are detritus feeders and don't go after live plants. I find that on the contrary, their appearance it indicates that you have a good and balanced ecosystem in your garden. I don't mind them at all. But I also grow carnivorous plants and fungus gnats are just food for them. They catch a fair number of these insects.
