Just an FYI, I've been using Nat. Chem. and new substrate and tubs on the boa I recently acquired for at least two weeks now and while running her through my hands after a bath tonight and getting the stuck talk shed off, I noticed what I can only assume to be a massive amount of eggs on my hands. I hope PAM works as well as advertised and may buy some, but just because you can't see the mites anymore ... eggs.
