She brought them from the shop. Most shops do not produce their own animals. They by them wholesale from brokers and private individuals and very rarely follow proper Quarantine protocols. She may have brought them to the shop with her or picked them up while she was there. Either way PAM used properly will kill the living Bejeezus out of mites. I tool in a rescue that had mites and had him cleared up within a week using it. Just make sure you remove and wash the water bowl and only place the animal into enclosure once the Provent a Mite is completely dry.
