Some fungus gnats have showed up, and unlike what some blog posts have said, they don’t seem to be attracted to apple cider vinegar. Has anyone found a trap that gets rid of these little things? I’ve put the plants outside for now, hoping that will dry them out and make the flies fly away.
Either the bacteria BTI, which Mosquito Bits contains.
Or the real fix, SF Nematodes. Nematodes will live in your soil and eat various pests, depending on the kind, and SF are good at eating fungus gnats larvae. Other Nematodes can be used for fleas and stuff too.

BTI and nematodes are the answer. You can also get liquid BTI instead of dealing with mosquito bits.
