Do it right the first time with the Provent-A-Mite. I bought and used the Reptile Relief until the PAM arrived.

More frequent applications are needed, as the eggs hatch, but you can use lukewarm water w/just a drop or two of dishsoap in it and soak your snake. The cage still needs treatment, but this is a process U can use until the P.A.M. arrives. I personally wouldn't use the betadine for mites, but that's just me.
