Treatment for lumber in new construction
If you use any of the boric acid spray-on solutions (I recall esp. for termite repel) don't do what a pest control firm did to us when I was new to housing stuff.
So the worker of this well known pest chain service goes to our basement and sprays the solution up at the plate and ring board of our foundation (atop concrete walls). Of course he coated the nearby copper pipes of our hydronic and plumbing system and it took me awhile to see the corrosion (esp. at joints of course), and washing with mild bases (baking soda paste) did not stop the degradation. I replumbed within 3 years.
The house wasn't built with the zinc coat joist hangers of today but I assume the boric acid would eventually damage those and fasteners too.
Careful, chemistry can bite!
