description Powderpost Beetle Overview
Powderpost beetle is a common name for several small wood-boring beetles, especially species in the genus Lyctus and related groups. Their larvae develop inside dry, seasoned hardwood and reduce the wood to a fine, flour-like frass that can emerge from small holes. Infestations may damage furniture, flooring, wooden objects, and building timber, so the name describes the characteristic powdery waste and the type of injury rather than one single species.
