Commercially, such critters are effectively killed in the wood-drying kiln.
Logs would take a long time to dry, depending on the size and type of
lumber.
I have been fairly effective in using a home-made kiln
Pick a sunny locarion
Separate the lumber (logs) with wood strips
Wrap the entire pile with plastic
A fan blowing from end-to-end helps remove the moisture
The heat will kill the little buggers, though I have no idea how long it
will take.
