The big chain reptiles stores move alot of animals and usually have no quarantine practice because they don't have time or space. The first BP I ever got came from another big reptile store and it had mites and ticks and was supposed to be CB. i took her back and now all my animals have come from trusted breeders. Best of luck with your problem. There is a product called reptile relief that is made with tea tree oil and is very safe on the animals. If I were you I would return her for a full refund and get a boa from a breeder. I have a friend in L.A. that deals with boas exclusively if you are interested.
