so i got my snake about a week and a half ago and i went back to the place where i got it and while i was there i held one of the other bps and it had mites....so i come home and look at my snake and i think she has em too...i can see a dark black dot under a scale on the bottom of her head...how do i treat this...by the way i think something needs to be done with this petshop anyways cuz it is nasty...all water dishes had poop caked in em ...some cages had a day or two old regurgitated mice in em the cages were nasty all together...what should i do?
