need some guidance about millipede mites!!

[teeks]

on my florida ivory millipede, there are very tiny white/yellowish mites on her. itd be really hard to get a picture because of how small they are. i do not think theyre parasitic, as they move about her body. but i think it might be annoying her. does anyone know if these mites can spread? i don't want to have to purge them because i think theyre beneficial to her, but i have cats, tarantulas, and snakes. i also don't want these mites spreading on me lol! im very new to owning millipedes.

sorry for the dogwater quality i had to zoom in all the way but heres what they look like. theyre all about the tank, too. they scutter quite quickly.
