Throughout my whole time taking care of reptiles aspen bedding has always been on the safe list for a substrate. Until today I have never heard anyone state that aspen can be a problem. A local breeder told me most breeders have stopped using aspen because it is too dusty. I have yet to have a problem with it as a substrate as of yet, but would be willing to switch out if it poses a threat, such as sani-chips.

Have any of you heard something similar. I feel ignorant for having never heard this.
