Good snake bedding.

I'm looking for idea's on new kinds of substrates I could use for various snakes and lizards.

Any ideas would be appreciated.

The substrate needed will depend on the type of enclosure and the critter's humidity requirements.

I'm looking bedding for a wide range of environments. But if you won't something specific I own two speckled king's right now.

For Speckled Kings, and most enclosures, I would use either aspen or white (without print) paper towels. This works well for most colubrids (those that do not require high humidity).

Actually, with rare exceptions, I keep my high humidity snakes in tubs and use unprinted paper towels. They get misted every day (with special attention on enclosure's warm side/end).
I know there will be other substrate recommendations, for high humidity critters, but I have never had a problem with what I use/do.

To help, with higher humidity needs, a wet hide can be placed in their enclosure along with the daily misting. An extra water bowl, placed on warm side, can help as well.

BTW Tanks are poor enclosures, for high humidity snakes, but, if one is used, at least half (if not 3/4) of the lid should be covered in plastic wrap (or can use something else that does not allow humidity to escape very fast).
