BP has mites, what do I do now?

I bought an enchi at petco a few weeks ago and she has been acting strange since, after talking to my breeder he said it sounded like she could have mites, and after coming home and examining her sure enough I found little black flea looking bugs on not only her but my spider too, my breeder told me to buy natural chemistry as that's what he uses, and research told me to give them a betadine bath, I have done both and they are now in a different room from the rest of my BPs, they have always been housed in separate containers, and I checked the others and they don't seem to have any signs of bugs. Am I on the right track? Any advice or tricks to try? HELP!

The Natural Chemistry Reptile Spray is great stuff.

Put them on paper towels for now and follow the directions of the Reptile Spray. Being on paper towels makes it easy to see the mites and it keeps them from being able to hide is substrates like mulch.

I had mites once and I killed them off with one treatment of Reptile Spray. What I did was spray everything, I mean everything. I sprayed the tubs, the table, the floor around them, the snakes, the décor, everything. After I sprayed the floor I vacuumed really well.
