Dude, those are veg flies and you will pretty much either need to change out your soil completely or you will need to put some diatemacious earth on the upper layer of the soil to help kill the flies. They have a constant life cycle in the soil and will continue to lay eggs over and over again. I stronly recommend changing out the soil first before the D.E. treatment.... even a light layer of sand on the top of the soil helps. I exterminate for a living so trust me on this one.
