Lyctid Powderpost Beetle
Lyctid powderpost beetles are about 1/4 inch long and brown. The body is elongated and slightly flattened. The head is prominent and not covered by the pronotum. Antennae have a two-segmented terminal club. The larvae are white and C-shaped, with the eighth abdominal spiracle enlarged. This beetle’s life cycle is six months to four years. Lyctids infest the sapwoods of hardwoods — mainly ash, hickory, oak, maple, and mahogany. Consequently, most infestations are found in wood paneling, molding, window and door frames, hardwood floors, and furniture. Imported tropical hardwoods are especially infested with Lyctids because of poor storage and drying practices prior to shipment to the United States.
Joists, rafters, and subfloors of houses are not usually infested with Lyctids, because they are usually made of pine or other softwoods. Lyctids rarely infest wood older than five years. Therefore, infestations are usually in new homes or newly manufactured articles. Infestation usually results from wood that contained eggs or larvae at the time of purchase. Typically the item was made from wood that was improperly dried or stored.
