ok i got these fuckers too they will fuck up you plant not right now but soon here is a little info on them.
Small pests that are tan to white colored and look like centipedes. They are very deadly to the plants, because they burrow down into the roots and damage them by feeding of them. Your plants leaves will begin to die off. They are found mostly in soil composites that have not been cleaned, like soil that has additives in them such as animal manure.
(I know it will smell funny but sterilizing the soil in the oven for 30 min can kill any pests in the soil, heat to 350 for 30 min.) They are easy to tell if you have them, because they come to the top soil when your plant is being watered, if you find you do have them, use Fungus Gnat Killer (“B.T." a non chemical,biological control) in the powdered form. One application should kill it, just to be safe repeat every 7 days to kill off the larvae. Tobacco juice kills them as well! And nematodes.
