Several types of beetles damage wood used for construction. They are commonly placed into three main groups: powderpost beetles, round-headed borers and flat-headed borers. These three groups include beetles from five scientific families: Lyctidae, Bostrichidae, Anobiidae, Cerambycidae and Buprestidae (Figure 1). Most species are less than 6 mm (� inch) long, but a few reach 25 mm (1 inch) in length.
