The term wood boring beetle encompasses many species and families of beetles whose larval or adult forms eat and destroy wood (i.e., are xylophagous). Powder post beetles get their name from the ultimate results of their wood eating: turning solid wood into nothing but a fine wood dust.
Wood boring beetles are commonly detected a few years after new construction. In many cases, the beetles will be of a type that only attacks living wood. Some beetles invade wood used in construction and furniture making.
