I have no idea. I wouldn't want it in my oven after it's been sprayed though. Maybe put it in your garage for a week and then hit it again with PAM. Also, I don't know how cold it gets where you are, I'd be tempted to just leave the wood in the garage over the winter, the cold temps out there will kill the eggs also, and any mites that do hatch out aren't likely to find a snake to feed on before they starve.
