How much wood to treat for Powderpost Beetles?
Found two joist where they exit and saw dust I sprayed the area near (borecare) , only 1/2 the basement and entire beam where I saw holes. and the flooring above. Do I need to do entire basement, i.e. sill plates etc or just do near the area where damage occurred?
Applying Boracare where you had the damage should be sufficient. While Boracare does aborb completely through the wood, it will not spread throughout to untreated parts of the wood. If there are already eggs in the wood that is not treated, you will have to reapply the Boracare if and when you notice activity or damage.
