I've been out of the wood destroying organism biz for about 20 yrs. Seems it was a new thing at the time here then, it might not have been pre treated at that time.
Good to know if it is now.
The crap I remember looked like a mix of glue and a dump truck load of shredded financial reports. Sprayed onto a crawlspace wall. lol
I have a patent advancing building envelope design.
