Anobiid Beetles

Anobiid Beetles most commonly referred to as Powder Post Beetles are the most prolific wood destroying beetle in the Pacific NW.  These beetles are usually found in older structures where the relative humidity in the crawl space or a garage reaches 13-19%.  The first sign that they are active is frass emerging from a pencil lead size exit hole that the adult makes when they leave the wood.  The larvae are actually ingesting the wood, causing the damage.  Left untreated, these beetles over a period of time destroy the structural integrity of the wood.  They are usually most active during the Spring and Summer months, as they feed less during the winter.  They attack both hardwoods and softwoods, mostly in the sapwood.
