The powderpost beetle is a small wood-boring insect known for its ability to damage hardwoods. Adult beetles lay their eggs in cracks and crevices of wood, and when the larvae hatch, they tunnel through the wood, creating fine powdery frass as they feed. This can weaken wooden structures and furniture over time. There are several species of powderpost beetles, including the Lyctus and Anobium genera. Infestations are often identified by small exit holes in the wood and the presence of powdery dust. Effective control methods include proper wood treatment and, in severe cases, professional pest management.
