The term powderpost beetle refers to several species of wood-destroying beetles that belong to three different families of beetles (Lyctidae, Bostrichidae and Anobiidae). They re-infest dry, seasoned wood year after year and the wood becomes completely riddled with holes and galleries packed with powdery frass. Powderpost beetles can infest any untreated or non-sealed wood article. Some species only attack hardwoods, while others feed only on softwoods, and some species will feed on both.
