UGGGHH!!! And where do they even COME from, how they find our snakes is just some kind of witchcraft! I sent many mites to the burning flames of mite hell a few weeks ago. PAM is amazing, one spray and they are GONE. My snake went from spending all day nosing at the glass trying to escape (I felt soooooo bad for her, it was TERRIBLE to watch) to now contentedly sleeping in her hide all day and all night.
I wish you the best of luck. Welcome to the "I AM LOOSING MY MIND!!!!!!" club.
