TINY black bugs on roots.

[Therion9116]

Today I was watering some one my Neofinetia, and during my inspection I noticed these tiny little black spots on the roots. After watching them for a short while I noticed they were moving around. I'm REALLY worried that I have something harmful living off of my Neos, and would like a little input on what they may be and what I could do about them.

They are really small; tiny as a pinhead, and I can't get any real detail on what they look like. Even with a magnifying glass I have a hard time seeing anything other than: Black, Round-ish, and move fairly quickly. I've found them on 5 of my neos (which are mounded in sphagnum moss in the traditional way). Any input? I'm about to pull my hair out, as I've dealt with pest after pest, and just FINALLY had a stretch of time without any problems... And now these.....

Invasion of the orchid-eaters. Boo.
