Lumber which has been improperly stored or dried should not be used, particularly if beetle exit holes are present. Many of the most serious infestations of ppb result from people using old lumber from a barn or woodpile behind their house to panel a room or build an addition. Powderpost beetles will only lay their eggs on bare, unfinished wood. Wood which is painted, varnished, waxed or similarly sealed is generally safe from attack provided no unfinished surfaces are exposed. Bare wood can be protected from attack by painting or finishing exposed surfaces. Beetles emerging from finished articles such as furniture were usually in the wood before the finish was applied. (Note: beetles emerging from finished wood can, however, reinfest by laying eggs in their own exit holes; sealing the holes prevents this possibility). 2.
