Sticky traps and let your plants dry back more that usual. Fungus gnats love moisture.

Mosquito dunks or bits. Usually they only sell one of these in an area but they are made from the same stuff. The bits/dunk release a beneficial bacteria into the water and then you have water that kills the larval state of the fungus gnats.

I could find bits so I crushed up a dunk and watered it in top. I also spread diatomaceous earth on top. Started to bottom water ACI trays. Top water once a week with recharge

Hey I’ve been typically on the same page used mosquito bits on fresh soil then rove beetles, beneficial mites and nematodes from there unless something gets out of balance I have had no significant issues with that. Was looking for the conversation I saw this morning to paste it on here to credit @jmystro with the very thorough breakdown of information on BTI, won’t catch me using that any longer on my plants… Apparently the little buggers can produce a build up of certain toxins that can get into the plant and be consumed by us. Thanks again @jmystro You’re a scholar and a gentleman!
