If you think the snake has mites,place in a white pillow case for a hour or so,after that time check the inside of pillow case,as the mites are darker in colour you should be able to see them...Theres a number of situations a snake can sit in water bowl,he-she is to hot,today and yesterday i understand...Mites....about to shed...once you eliminate any of those you may find your answer...MARK
