I rescued an 11 foot albino burmese once with mites. I treated her the same way I treat me ball pythons. I got a big rubbermaid container she would fit in, I put her in it and sprayed her down good with Reptile Relief. I prepared her enclosure and treated it very good with Provent-a-Mite. After being in the tub for 25 minutes I took her out and put her in the bathtub, rinsed all the RR off and let her soak for about 15 minutes (thats the hard part, probally best to run water in the rubbermaid and put it back in there) Soaking afterwards helps rehydrate the snake. PAM kills mites be dehydration and can partially dehydrate your snake as well. After soaking a while wipe her down and put in treated enclosure. BAM!! no more mites, has worked for me everytime, with burm and several balls, I have also treated several Boas this way. Make sure to follow the directions on the PAM can and have NO water in the enclosure until the PAM is completely dry.
