Powderpost beetles are a group of seventy species of woodboring beetlesclassified in the insect subfamily Lyctinae.[1] These beetles, along with spider beetles, death watch beetles, common furniture beetles, skin beetles, and others, make up the superfamily Bostrichoidea. While most woodborers have a large prothorax, powderpost beetles do not, making their heads more visible. In addition to this, their antennae have two-jointed clubs. They are considered pests and attack deciduous trees, over time reducing the wood to a powdery dust. The damage caused by longhorn beetles (family Cerambycidae) is often confused with that of powderpost beetles, but the two groups are unrelated. Their larvae are white and C-shaped.
Powderpost beetle larvae spend months or years inside wood while developing, feeding mainly on the starch content. Their presence is only apparent when they emerge as adults, leaving behind pinhole-sized openings, often called “shot holes”.[2] They may also leave piles of powdery frass below. Shot holes normally range in diameter from 1⁄32 inch (0.79 mm) to 1⁄8 inch (3.2 mm), depending on the species of beetle. If wood conditions are right, female beetles may lay their eggs and re-infest the wood, continuing the cycle for generations.
