Powderpost Beetle

Commonly found in deciduous hardwood materials, unfinished lumber, or wooden structures like flooring, rafters, and furniture.

Larvae feed on the starch content of wood, particularly seasoned hardwoods like oak, ash, and hickory.

They are nocturnal and often go unnoticed until adults emerge through tiny round 'exit holes,' leaving a fine, flour-like powder (frass) behind.

They are significant economic pests that can cause structural damage to buildings and destroy expensive furniture; they offer no direct benefit to human ecosystems.
