Resurrecting the thread again.
I cut and milled a walnut tree in AZ 3.5 years ago. The 9/4" wood was air dried for 16 months when I discovered the dust from some type of beetle (powderpost?) I did some research, purchased bora-care and applied it as directed. I was under the impression that the beetles would leave within a year and never return again. I milled some of the wood two weeks ago. The sap wood has significant damage and the beetles continue to make dust.
I called the technical rep who makes the bora-care. The rep told me there isn't any fool proof way to make the wood beetle free. I believe he said the eggs could be in the wood for 5 years before they hatch and start the cycle up again.
Not sure what to do now. Someone suggested putting the wood in the attic. The outside temp in phoenix next week is 118 degrees in the shade. My attic will probably be 170 or so. I could put some wood up there for a several days.

Sorry my message is so long, I didn't have time to write a short one.
