If you can bake the wood in the oven at a low temperature (around 150 to 200 degrees if i recall correctly) for like an hour, it should kill off any bugs. It should vaguely smell like you're roasting wood.

If they are true snake mites, it would probably be best to spray the log with Provent A Mite, let it dry out, make sure the smell is gone, and then use it.
