I received three bp's on jan 3 of this year that i ordered online. Three days after receiving them I discovered that they were all infested w/ mites. There tubs were already treated w/provent a mite ahead of time and I treated them w/ reptile relief every three days for about three weeks, wich seemed to do nothing. But i was sure the mites had run there course and were gone. Two of the three have shed out on there own since and the other had a stuck shed wich i removed after soaking. I keep my bp's on paper towel substrate and i hadn't seen any mites for about three weeks until tonight. I was cleaning tubs and there was one single mite crawling on the water bowl of the same snake w/ the stuck shed. I know they're not nesting in the tubs because i completely clean and change the paper in them about every three days. Any idea where they're coming from? And any idea on how I can get rid of them for good? I,ve had no luck w/ reptile relief or zoo med mite killer. I heard the black knight works well but it is no longer on the market. Any suggestions would be great...thanks.
