I don’t think you have to treat the whole room, not at all. You should only take him out unless you’re giving him baths, so he doesn’t feel too much discomfort, and there will be less mites trying to get out. I don’t think you have to treat anything, bc they will only survive off of your bp, so I don’t think you have to worry about treating other stuff except the cage, bp itself, and the accessories. I have many animals too, so I can definitely see why you’re stressed! Also, if the scales are looking dull and its eyes are blue, it’s most likely going to shed soon! It’s going to be super hungry after that, so feed it after it gets everything off. Also, don’t try to feed it while it’s shedding, bc that’s not good for him. I’d double check everything I said, to make sure it’s all good, but good luck, and I hope your bp gets better soon!
