When you get the PAM, put fresh substrate (enough to perform a cage cleaning with) in a container and lightly spray it down with PAM. Do this outside of your herp room. Let it sit overnight.
The next day remove all of the old substrate, hides, water bowls, etc. and give the cage a thorough cleaning. Place her back in the enclosure with the substrate you treated the night before. Wash the water bowl in the dishwasher, and spray her hide with PAM and let it sit out for a couple of hours.
While PAM claims to give 30 days of protection, I would treat another batch of substrate in two weeks and repeat the above process a second time.
