Beetles in Reclaimed WWII Pine Flooring: Powderpost, Not Pine Beetles—Old Infestation

1/8" holes with fine dust in 5-year-old milled WWII-era pine flooring. Owner feared southern pine beetles. Expert: powderpost beetles—bark beetles don't infest milled lumber. WWII wood is too old (starch depleted) for active powderpost infestation.

Dust likely from old larval tunnels exposed by recent milling. Test: mark all holes with grease pencil; watch for new ones. None expected. No treatment needed. See powderpost guide.
