Ok thanks for that info! Really I would rather not mess with the scorps. So now that you guys have told me this I'll just put the substrate back in.I don't know if these mites can go to reptiles, but they seem to not be harmful to the C. vittatus. They are VERY commonly found on them. The have all died off in time in captivity here. I've made no attempt to remove them. They just die pretty quick. I don't know the how's and why's, but I know they do. I wouldn't stress too much. If they explode in numbers, then it's time to start worrying. Sure, go ahead and try to remove them, but I've had no problems with them.
