| Mites are so small, you will not see them without a jewelers loupe or microscope. Since spider mites often make webs you can just barely see, you can sometimes see a speck of dust moving slowly along the web. That is a mite.
I would guess you are seeing gnat larvae. Any tiny fruit flies around? For that, I recommend mosquito dunks from a home-center. A chunk in the water that you give your plant will clean up the problem for a while. It is a biological control, with organisms that eat the larvae.
