Fungus Gnats: I think I got em where I want em. 
Someone on this forum tipped me off, and I did a lot of research on state ag websites, etc.
Try using "mosquito dunks" which have an active organic ingredient called BTi. (stands for Bacillus thuringiensis subsp. Israelensis). Can be found in hardware store and some plant oriented stores. Make sure you see BTi on the label, not just BT.
Some of the dunks you have to chop up. I found one that is water soluable time release pellet pouch. Either way, immerse in a bucket of water, let it sit 24 hours or more. I think some folks leave a dunk in their watering can.
Drench the potted soil with the TBi water. If you gotta a lot of fnking gnats, you'll see their little tiny white squirming baby larvae in the run-off water. They love the stuff! They eat it and die!
Repeat once a week for three weeks. You will see immediate improvement from the very first drench, but needs a repeat. I thought I had them all the first time, waited ten days, and they started coming back. It doesn't kill the adult flyers, just the larvae.
For the flyers, place yellow sticky straps around your pots here and there placing horizontal. It won't get all of them, but it provides a platform for their brothers to see. The traps also help monitor the level of infestation.
