Lyctus is a genus of wood-boring beetles commonly known as powderpost beetles. These insects are known for their ability to infest and damage hardwoods, including furniture and flooring. The larvae of Lyctus feed on the starches in the wood, creating fine powder-like frass as they tunnel through the material. There are several species within the Lyctus genus, with Lyctus planicollis being one of the most recognized. Infestations can lead to structural damage, making it important for homeowners to identify and address any signs of these pests promptly. Effective control methods include proper wood treatment and maintaining low humidity levels.
