Thanks for reaching out about Molly. Aging hamsters can often suffer from adrenal diseases which can lead to polydypsia/polyuria (drinking and urinating often), dermal conditions and decreased immune system. That could have manifested in a proliferation of previously existing mites. Often mite treatment need to be repeated to end in remission. Testing for adrenal disease if difficult, probably best investigated with an ultrasound. Treatment is even more problematic. Trying to treat the resulting symptoms (scratching) might be more effective. Good luck.
