PAM is the best stuff out there for mites - follow the instructions to a T. I hope you ordered enough of it because you should do mult. Treatments on the rack (heat tape area is a hot spot), tubs and around the infected area. If the racks are near/on carpet, vacuum. As Schneider said use paper towels for sure, try not to cross contaminate any other areas or snakes. With proper protocol you can rid this no problem!
