Hello, I recently discovered these tiny mites/insects in my indoor potted Meyer lemon tree. They are very fast moving and there are ALOT of them. This plant has been struggling on/off for the past few months, are these beneficial mites or root aphids or something else? Should I be concerned? If so, any recommended treatment? They are so small it is hard to capture them on camera, but they are very small, maybe the size of a poppy seed or slightly larger. They are fast-moving and do not have wings. Relatively long antennae but I cannot tell if there are 6 or 8 legs. Please see the following video for better visualization. This plant has a lot of sentimental value so I am not willing to part with it easily. I appreciate any help available!
