I just went through this with Carmen. I used Provent a Mite (PAM) and Reptile Relief (RR). If I had to do over, I would skip the RR and just do a soak.

While waiting for your PAM to come in (and PAM is the best - kills'em dead! be sure to READ VERY CAREFULLY the direction), get any extranneous cage toys out and get them cleaned and disinfected. I wouldn't put them back until your PAMing is done. Switch the substrate over to something very easy to clean and replace and see mites; lotsa folks recommend white paper towels or plain newsprint. I used white flannel fabric (cuz I had some and I was worried Carmen would poke a hole through paper towels where the temp probes are).

Good luck!
