I agree that a snake's eyes are a problem when it comes to mites- soaking won't help that either, it's not like you can dunk his head- & no, don't spray his face either. Sometimes you can wipe them off with a damp tissue or Q-tip, but those wretched mites really hang on. Both the soaks & Natural Chemistry are good methods with the least harm, but also might not get 100% rid of the mites.
