Most likely you have fungusMost likely you have fungus gnats. The gnats don't harm your plants but lay eggs in the soil. The larvae of the gnats live in the top of the soil feeding on decaying roots and wet soil. Remove and discard some of the loose soil around your plants without disturbing the roots. Add fresh sterile soil and a thin layer of sand to the surface of the soil. Let the soil dry out and only water when your plants start to wilt.
