Okay, I think my Spider has mites so I intend on treating my other ball's and boas enclosures, Provent-a-Mite is for enclosures ONLY, but do I have to use something like natural chemistry directly on the snakes and Provent-a-Mite on their enclosures or is Provent-a-Mite good enough? I'm just about to order it but I wanted to make sure I only need Provent-a-Mite and not both, so I should get it within the next week.
