Three groups of wood-boring beetles—Powderpost, Deathwatch, and False Powderpost invade
and damage wood furniture as well as structural and decorative wood
inside of buildings. The beetle larvae feed in and do most of the damage
to wood, and when they reach the adult stage, they emerge through round
exit holes, which they create by chewing through the wood surface.
Adults of some species also bore exit holes through plaster, plastic,
and even soft metals that might cover the underlying wood.
