yeah these can really hurt your plant if they are fungus gnats.
if you see any flying around get some sticky yellow bug strip.
but like i said above let your soil dry out, damp soil is just beggin to be attacked by these things
and sorry i was wrong by saying no they cant hurt your plant, they can, and like anything in larva form.
they eat alot....
the soil you have is organic and they love that stuff.
