I would not worry about reptile mites in your bedding, it is my understanding that they can't survive with out a reptilian host (they are like fleas but just for reptiles).

If you don't have a can of PAM (provent-a-mite) get some, follow the directions on the can and you will be mite free. You can purchase PAM from Reptile Basics, the link is in my sig.
