>>Although I use primarily newspaper for my "at home" herps (and a variety of natural substrates for my exhibition herps at the wildlife center I am curator of), we also use aspen for a couple of our displays. It has been my experience that some snakes are extremely sensitive to aspen and other wood based products. It seems that the dust produced by these substrates causes irritations in the linings of various airways. I would recommend that you might consider switching to newspaper for a while and see if you notice a difference. We had to do this with a few of our herps and everything came out fine in the end.

I have had snakes kept on aspen "dry out", loose scales, get it in their mouths when burrowing, and develop breathing problems. Now I use Ecofresh (a recycled-newspaper based pebble-like substrate) for my desert herps, and bed-a-beast for anything requiring moisture. Haven't had a problem with either, except the bed-a-beast does need to be checked weekly for mold.
