Mites suck! Sorry to hear that. I used NIX lice cream. It's a small bottle meant for humans but dilute the small bottle in 4L of distiller water and it worked like a charm. I went to a bare bones setup and sprayed everything including the animals two day in a row. Then once a week later and then again two weeks later.
I had no reptile spray available locally and would have to order from the states. If you have something for reptiles that others have had work then I always suggest erring on the side of caution and use that.
Good luck.
