We have a friend who discovered powderpost beetles in their wainscoting on a plaster wall around their fireplace. The wainscoting is painted. Is there a product to treat/kill the beetles over painted wood? The insect control technician who diagnosed the problem said products to treat/kill the PPDs in the wood such as Boracare wouldn't be effective since the wood is painted. Tenting the home at approximately $30,000 is not financially feasible for our retired friends. What can they do?
