would could be wrong with my plants

I do not know what's going on with my plants I had seen some gnats but I haven't seen them In about 3 days however I did look 2 inches into the soil and I see a lot of little white larvae my plant is in vegetative grow this is my first would it damage the plant if I was to put it into a different pot and how will I get the larvae off the roots once I transplant I would appreciate the help iv attached pictures

Put a potato shaped like a spike in the soil if its fungus gnats they snack on that. then remove the potato and repeat. I would also let my soil dry out before the next watering. Your probably watering too much. There is lots of information about getting rid of these pests. Try a search. The potato probably wont solve your problem but it will give you an idea of whats going on.
