So I totally washed out his cage and him, switched out one hide but kept the other in because it didn't have another but I had washed that one off too. Put him on paper towels, and gave him some good soaks. But I look at him today, an he is soaking in his water bowl. Surrounded by dead mites. I checked his cage for any living ones, couldn't find any. What should I do now? Can mites burrow in cardboard like hides? (don't have any plastic ones)
