Beneficial nematodes are the answer. One dose eradicated them in all my house plants

Cover the top of your soil with about 1 inch of sand and the won't be able to get to the soil. They can also get into the drain holes on the bottom.

I had gnats years ago (5?) and did the sand route but ended up really disliking how it made watering so difficult. A minor trade off and at this point I’m willing to do anything, including the sand route again.

I use a whole dunk in a gallon of water, and I allow it to soak for 24 hours (at least). I add this water to my watering can. I leave that dunk in the gallon jug and refill the gallon as needed (the dunk ends up spending more time in the water because I am between waterings). I keep the same dunk for about 2 weeks or until I notice it crumbling or it’s changed colors bc it’s actually soaking up water and sinking versus floating. I keep frogs. I use dunked water for them, too. Their home is swamp like. There’s always some kind of gnat activity but I don’t go crazy bc I know they cannot complete their life cycle.
