Mites in new store bought pine shavings?

Mites in store bought bedding is very unlikely to have mites. TSC pine shavings are usually kiln dried, which would kill any mites in the wood.

I presume it's ok for them to eat wood shavings - our girls seek out the decaying lumber in the yard and regularly eat the small shavings from inside the logs. I guess it's a form of grit. They also eat soil - ours is sand. With the dead grass and weeds and no bugs, there's not much else - natural roughage I guess; better than store bought grit although they have access to that all the time. Thus far, no crop issues. My concern is the wood shavings turning into a nasty clump in their crop but it hasn't happened yet.
