I have NO experience with Boa's other than I have babyset a few. Wh00 - do you think it might be a good idea to treat her cage once with Provent a mite just in case. The reason I say this is once you see the mites....YOU HAVE REALLY GOT THEM. You cannot see eggs or newly hatched mites...in fact you don't see them until they are adults. I don't know....wait for a response.....but that is what I do with EVERY new snake I get.
