True Powerpost beetles are a group of woodboring beetles in the insect subfamily Lyctidae and the false powderpost beetles, the family Bostrichidae. These, and other woodboring beetles Anobiidae (anobiid, Anobium punctatum (common furniture beetles), and deathwatch beetles), all fall in the superfamily Bostrichoidea. The damage caused by the family Cerambicidae (the most common is the Old House Borer) is often confused with that of powder post beetles. However the damage is often very old, and of no consequence.
