They are fungus gnats and their life cycle involves some back and forth between the soil and the plant. If you take some landscape cloth (permeable black plastic) and cover your soil, (just like a barber covers you with a cloth around your neck) you will break the cycle. An inch of perlite as the top layer in the pot will do the same thing. Diatomaceous earth works, too, but after watering it can clump up and become expensive mud. They are generally a sign that you're watering too much.
 
Predatory mites are awesome. I used grub grenade and they keep my soil free of lots of thing like Knats and larvae in soil, root aphids and more. Hope you get those bastards under control lol.
