Wood borers belong to the family of beetles whose larval or adult forms eat and destroy wood. They are important in the turnover of trees by culling weak trees, thus allowing new growth to occur, but in homes they can cause severe damage to furniture. They are commonly detected a few years after new construction. Wood Borers turn wood into a mass of wood dust. The tiny pin hole in a wooden surface is a symptom of wood borer attack. Wood borer infestations are far more likely to happen in areas with high humidity, such as poorly-ventilated crawl spaces.
