couple questions about cooking decor in stove..

[DeesBalls]

I have a big bag of multch (for outside) and i was going to use that for my ball pythons, instread of paper towel, but knowing its for gardening use, im sure there something int here that isnt good for snakes, ...

1. if i cook that in the stove, to kill off all potential nasties, would it be then safe to use? Its prolly about 2 yrs old (the bag of multch) and was just curious, not a huge deal, just wanted to be safe before i used it, if i did....

2. when baking outside sticks/limbs, how long at at what temp do you usually do it? i have nice sticks outside iw ant to put in bearded dragon enclosure, and then some in my sullys tub for some decor.

thanks in advance
