Powderpost Beetle

Dry seasoned hardwoods, flooring, furniture, wood paneling, and structural timbers.

Larvae feed on the starch, sugar, and protein found within the sapwood of large-pored hardwoods like oak, ash, walnut, and hickory.

Female beetles lay eggs in the pores of unfinished wood. Larvae bore into the wood, creating tunnels. Adults emerge through characteristic small 'shot holes' (1-3mm), leaving behind fine, flour-like dust called frass.

Significant structural risk to wooden structures and valued antiques. If left untreated, they can reduce wood to a powdery dust, compromising the integrity of furniture and building frameworks.
