Turning Wood into a mass of find powder
The term “powderpost” comes from the fact that the larvae of these beetles feed on wood and, given enough time, can reduce it to a mass of fine powder. Because of this behavior, they are considered pests.
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”. They may also leave piles of powdery frass below. Shot holes normally range in diameter from 1 of beetle. If wood conditions are right, female beetles may lay their eggs and re-infest the wood, continuing the cycle for generations.
