I thought I'd post this as it's pretty comprehensive. I'm having better success lately by trying to let the top couple inches of soil dry out and using mosquito dunks in my water. I also use the yellow sticky strips. I do have Gnatrol WDG on the way. I'm glad the Insect ID lab at Va Tech forwarded this to me just in case things get out of hand again. Thought I'd share.

This gave me a better understanding of how those guys work.  Thanks Michael.

That is a great source of information!  Thanks for posting it!

Michael, thanks for sharing that information. I too have started to let the top 3-4 inches of the soil dry out by watering from below through
the holes in the bottom and sides. I am also using sticky traps and Carnivorous Plants and everytime I add any water I used Gnatrol. I have only seen
one or two in the past week. Don't want to say I won this battle yet.

Frank and Suzi -- you're welcome.
Mike, I hope you have those little crap weasels under control. They drive me crazy. They fly all the way from my grow room into my bedroom and buzz around my lap top screen as I watch a lot of Netflix in bed at night. Mine are almost under control, but I have over 100 1 gallon figs in my house at windows, a ton of house plants and at least another 100 cuttings in cups, so the cost of treating steals the cost of a dinner out every time I have to restock my anti-gnat stuff. And there are always smudges on my lap top screen. Yeah -- I know --- pretty minor on the list of life's problems -- but . . .
I use house plants as an air filter so I do have a pretty large amount of foliage in my house and I do propagate and gift a lot of plants so anything that gets into my mellow space I resent.
NASA did some really cool research on which plants filter which toxins -- like spider plants will trap benzine, for example.
