Yup, keep pam around and use it monthly to quarterly. When I get a new snake I spray them down and wipe them off as well as spray down the box and bag it came in.
You should NEVER apply Provent A Mite directly to the snake - EVER. It's even a warning on the can.
A VERY light misting of the tub to pre-treat it, and allowed to dry completely is all you need for preventative maintenance.
