a big waterdish in her enclosure will help out, since she'll probably spend a lot of time soaking herself to drown the mites.
get rid of allll the substrate, any wood hides. I cleaned out mine with natural chemistry reptile spray every three days and rubbed mine down with it as well. rubbing a little bit of vegatable oil on her as well will help.

Also, anything in the tank that you still want, I would soak in steaaaminng hot water with a little bit of bleach. then let it air dry.

When I picked up my baby she had a huge mite infestation. It sucks. But she'll be so less stressed when they're gone and she'll be way more pleasant. It'll take a while and its a pain in the ass. Gooodd luck.
