If that red oak and white oak was not sprayed with borate once you sawed it, and if you just plan to sell it air dried versus kiln dried with a heat treatment, you do risk having PPB's in the wood, and that could cause some pain and suffering.  In Georgia, my experience has been that if you do not spray or do not kiln dry with a heat sterilization at the end, the risk of PPB's is a real issue.

WDH.  Thanks for the input.  I am planning on building my solar kiln soon, and will also be looking at a way to sterilize wood.

Are there PPBeetles in Iowa? or are they a differant type of beetle? I found this article from  the Iowa Extension website that says they are not a problem.https://hortnews.extension.iastate.edu/powderpost-beetle

There are four or five technical errors in this document from Iowa Extension.

Thanks for response. I know you  know the facts about the beetles. I researched it a little more and found that the damage from the  false powderbeetle is one of the important bits of information left out. I had searched only on the PPB.

Is the FPPB responsible for Oak Wilt & would trees infected be quarantined or just a good standard?

It is not related to wilt

Yes, PPB in Iowa.  I would imagine that they are everywhere.

We have entertained a bunch of "bugs" in the basement supporting members of our National Register listed log cabin over the years, with plenty of pin sized holes to prove it. Every exterminator has told us that they will not bring the building down, that they are merely a nuisance, aesthetically.   The only truly effective removal strategy is to tent the building & use a gas not much different from the Nazi death camp variety, three days with security posted.

 I wonder if heating up the basement to 150 for 24 hours would do it?   That's a lot less risk than a dangerous gas, and a lot cheaper.

31+ Years here, and we're still standing.  FYI the building was built in stages from the late 1920s to the late 30s.  The construction ranges from pure log, to slab sides, to conventional framing.   Because of leaks in the HVAC ductwork the basement stays dry and conditioned.  Mostly dirt floor.

Each crop of insects, if they are still active, makes tunnels in the wood.  These tunnels have a combined effect of weakening the wood, little by little.  If the structure is built six times stronger than needed, you can indeed lose a lot of strength.

Why not spray the place with insecticide like Timbor or similar? It will not kill the insects in the wood, but will kill the ones who emerge, or the ones who come up to lay eggs, and will interrupt the life cycle of future infestations.

I would probably also treat the earthen floor, as well as spray with a long lasting professional grade contact pesticide.

The folks who are telling you the critters won't bring the place down are the ones who don't own it.  I have seen old barns and other structures brought down by bugs.  That's what they do.
