I had two adult normals in the early 90s that might have been WC. They were pretty docile but did come infested with mites. They ate well but never got as fat as my current BPs. There was only one petshop near me that had reptiles and I bought a can of something there to treat the mites. It wasn't PAM. The guy told me to spray the inside of a snake bag and put the snakes in the bag for about 5 minutes so that's what I did and it worked and didn't seem to hurt the snakes. I just soaked the enclosures in a wicked strong bleach solution overnight and it controlled the mites pretty well. It seemed like most anything you bought in pet shops back then was covered in mites. My burm was infested as well as all the boas I bought from stores. I wish back then I know what I know now.
