Powderpost Beetles

Powderpost beetles, like their name suggests, are most widely known for reducing wood to powder as they bore holes in it in their larval stage.  These beetles are usually under a quarter inch long, and have jointed antennae, large heads, and straight wings.  The larva of these beetles feed mainly on trees but will also move into structural frames or any other wooden objects that are conveniently available such as furniture, wooden tools, or even toys and books. 

The larva bore holes, leaving small piles of fine dust in their wake, leading them to be a serious nuisance everywhere they occur.  The small holes and dust left by an emerging adult are often the first signs of an infestation.
