powderpost Beetles

Their larvae are white and shaped like the letter “C.” The larval stage is the life stage that causes the most damage to wood infested with these destructive, wood-eating pests. Powderpost beetle larvae eat sugar, starch, and protein found in wood.


These beetles pose no direct threat to people.; like termites and carpenter ants, powderpost beetles are a type of wood-destroying insect and are capable of causing extensive damage to wooden structures on your property. Powderpost beetle larvae feed on the interior of wood and, after developing into adults, leave behind exit holes on its exterior surface. In addition to damaging structural wood, they also cause damage to personal property like books, furniture, and framed pictures.

Female powderpost beetles lay their eggs on stored lumber. They find their way into a building, often emerging as adults from a finished project. Adults may also enter into homes on their own when they are out foraging for food. Powderpost beetles hitchhike inside homes in older pieces of furniture or antiques. Additionally, wooden items stored inside barns or other outbuildings often become infested with powderpost beetles.

Female powderpost beetles lay their eggs on the surface or just underneath the surface of a piece of wood. Adults live outside but are attracted to the lights on buildings. They then find their way inside through openings around doors or windows. Their larvae live inside the piece of wood they are feeding on. Once they complete their development, they emerge as an adult, leaving behind an unsightly exit hole in the wood.
