Do you actually have a mite problem? PAM is dangerous stuff that in my opinion shouldn't be used as a preventative measure. It can even be dangerous to people. There are other products that aren't as dangerous and some that are safe enough to apply directly to a BP. These safer chemicals are what I would use as a preventative measure... the atomic bomb that is PAM simply isn't necessary and is just too risky.

But if a snake actually has mites PAM is the first thing that I would use. You have to determine when the good outweighs the bad.
