Got a juvenile BP 04/14 as he was just beginning his shed. (Adopted him) yesterday and today notices him soaking in water bowl. Took him out and found no mites on him. There were mites floating in his water.

So my question is, do I need to do something ASAP or can I wait on my order of PAM? He is my son's snake. If Im waiting, can he handle in the meanwhile or will mites spread around the house/people?
