What are these bugs and what to do about them?

They look like predator mites or soil mites. both of these are not too big a deal as long as they don't start crawling up the plant If you look at my first Diary of the Galaxy I think these look similar to what I had. it was from over-watering and having an abundance of organic material for them to break down and thrive on. If you don't see webs and no white discoloration spots on the leaves where they're at they could just be regular beneficial mites. if they get to out of hand though they become a nucene. If your humidity is high try to get that down and try to et the tops of the containers dry out a bit before watering again. also keep and eye for anything else
