Having a heat wave here and my garage getting to hot and thinking about moving the Bp's to the basement.

Main problem is there is some moisture in the basement causing a little bit of mold to form on wooden items in the basement, not alot but a little and i am able to simply wipe it off and clean it, but worried will it hurt my snakes? i keep their cages cleaned weekly so more worried about what they are breathing. Any help would be appreciated as it stays cool down there and my venting system from my house has 2- 6" pipes feeding heating down there for the winter and want to just make it permanent for them down there
