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?

It depends what the dust is like. That will narrow down the type of borer. Not all borers are the same. Is the powder soft like talc when rubbed between finger and thumb, or course to gritty?

Fine dust is lyctus, course is probably anobium. The latter is far more destructive.

I always thought that holes in the timber are an indication of borers. Most of the time they only go for the sap wood so you can often cut that bit off and solve the problem. The other thing with small pieces is to put them in the freezer for a week and that will kill bugs and eggs.
