Our barn has powederpost beetles and much of the wood is whitewashed. How do I apply bora-care to whitewashed wood? Should the whitewash be power-washed off, wood allowed to dry thoroughly, then Bora-Care applied? Would the power washing simply drive the eggs/larvae deeper into the wood?
Bora-Care has to be applied to raw, untreated, and unpainted wood. If you have whitewashed wood you will need to remove the whitewash so that the Bora-Care can soak into the wood. You would need to allow it to fully dry and then apply. You can whitewash again once the Bora-Care has fully dried as well. If the power-washing drove the eggs deeper the Bora-Care could still get to it as it soaks into the wood but you would need to apply to all sides of the wood. Please review the BoraCare product label and Dimensional Lumber Technical Bulletin for more information.
