My solution was to completely transplant into new soil. I tried to get rid of as much of the old soil as possible, and keep it away from your grow spot when you do. I even went as far as to flush is with Phs balanced water before I put it into the new soil. Make sure if you do that, when you re-pot it you make room for the roots and dont balls them all up.
Another trick I picked up on these forums is using dryer sheets. Put them ontop of your soil after you have fresh soil. Make sure they don't get wet when you water but I've used them since I transplanted and I have zero gnats.
I dont understand why your goi g on about fungus gnat? He has mildew. Just because you have mildew,does not mean you have fungus gnat or vice versa. If he has mildew then it is almost certainly due to humidity, not fungus gnat. Mildew: lower the humidity. Fungus gnat: put a woman's stocking over your pots, 100% guaranteed to stop anything from getting to your soil.

Powdery mildew really needs the humidity to be high to set in and keep thriving, all fungus gnat needs is wet soil.
