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. They are therefore considered pests.

Powderpost beetles spend months or years inside the wood in the larval stage. Their presence is only apparent when they emerge from the wood as adults, leaving pin hole openings, often called "shot holes" behind and piles of powdery frass below. If wood conditions are right, female beetles may lay their eggs and re-infest the wood, continuing the cycle for generations.

Wood preservatives can be used to treat the wood and prevent beetle infestation. The most common treatment uses boron. Items that can be infested by powderpost beetles include any wooden tools or tool handles, frames, furniture, gun stocks, books, toys, bamboo, flooring, and structural timbers.
