Just to make things clear: I do NOT have humidity issues, and that is not why I want to change substrate.

Eco Earth gets clogged very easily in the tracks of my terrarium's glass doors, and it's incredibly inconvenient. I currently have my boys on paper towels, which work perfectly fine, but I've always really loved a natural-looking environment. So, I'm considering something like Repti Bark, but I've noticed mixed feelings about it. I've heard that it can be really dusty, that it's "uncomfortable", even that you can get splinters from it. Can anyone confirm or console these concerns?

I've heard some similar things about cypress mulch, too -- that it will dry out and get dusty and prickly after some time. Any other info on that?

And if these two aren't quite adequate, are there any other suggestions for "natural" looking substrate that isn't as loose and messy as Eco Earth?
