I plan on having exposed truss ends on my house (no soffits). If the trusses are treated will Boracare still work to kill carpenter beetles.
You can use Boracare on pressure treated wood as long as there is no stain, sealant, or paint on the wood. If the wood treated with Boracare is outside exposed to the elements, then you want to apply a water sealant after the Boracare has dried.
