Soak the snakes for a good long while to drown as many of the mites as possible. Assume that your current collection of snakes is likely to get mites as well if you are unable to treat these new ones today.

Short term, soaking the snakes and keeping them on paper towels is your best bet. I'm hoping you have actual cages for them prepared, and you weren't relying on the containers the people brought them in to use as permanent caging options?

You'll want to get actual mite treatment, both a spray for the snakes (reptile relief) and Provent a Mite, as soon as possible. Here's our article on treating mites - honestly, the best and easiest way to get rid of them is to get the right products and start ASAP!
