Mites are host specific.
If you have snake mites, I would recommend you to treat this snake with PAM, provent a mite which will treat all staged of development of mites, and I would also recommend you to treat any other snakes you might have.
If you have rodent mites in your colony I would also recommend you to treat them.
Quarantining new addition whether rodent or snakes and treating for mite preventively is always a good idea.
