For future reference, if you want to bake some wood to kill insects, it's done on a very "low & slow" oven temperature, not over 250*....200* is fine, and it helps to get the wood wet first too, so it won't burn so fast in the oven. It's the heat & length of time that kills the insects, & it will dry out as it bakes for an hour or so. Keep an eye on it too...don't set fire to the kitchen.
This. Bear in mind that pasteurization for milk occurs at 145*F for 30 minutes. So, baking wood at 150-175*F for 60 minutes to let the heat penetrate deep into the wood where insects may have burrowed will be plenty.
