Thread: Can timber with borer eggs in it be identified?

Bought some blackwood slabs from a private seller 8 or 9 months ago and stored them in racks under my house where it's nice and dry and a much more stable climate than outside.

Finally pulled the slabs out a few days ago for the project they were intended for and noticed dust mounds in a few places on each of them, which were around the flight holes for borers which had happened since I stored them.

I'm hoping that the LVL bearers and joists and yellow tongue accessible to the borers under my house aren't attractive egg laying sites.

I now have some nicely dimensioned and dried live edge firewood for my shed heater.

I think I might set up a covered rack outside against my steel shed for future timber.

The next concern is that I was going to use the timber to make items to sell. Obviously I don't want to be putting infected timber into people's homes, which would have happened if I'd made and sold the items when I got the timber 8 or 9 months ago.

Anybody know if there is a foolproof way of identifying borer infested timber that has yet to fly?

How long should I hold timber to be sure that no flight holes are going to emerge?
