How to Identify Powderpost Beetles



Powderpost beetle is a classification of several different wood boring species of beetles that are usually 1/8″ to 3/4″ long. This group of beetles can live inside wood while feeding on it for years until they are fully matured.


These beetles are known for boring small holes in wood both in inside and outside environments. They can be difficult to detect as they bore through the inside of wooden window and door frames, hardwood floors, and even wooden furniture. Adult powderpost beetles often provide the first detectible sign of infestation as they create small exit holes in wood up to 1/8″ on their way out to reproduce.


Powderpost beetle infestations are easily confused with termites because of the damage they inflict on wood. The boring beetles can feed on wood for years, weakening the structural integrity of the wood.


Similar to other wood eating pests, powderpost beetles tend to avoid wood treated with paint or varnish. Untreated wood should be checked for exit holes and females laying eggs on the exterior of wood products. Powderpost beetle eggs not removed will cause a new infestation in the wooden structure.


The most economical control method is removal and replacement of all known-to-be infested wood pieces. Where damage is limited to a few pieces of wood, this is the simplest and most practical solution. Removing infested wood and replacing it with un-infested (preferably treated) wood will eliminate the problem in most cases. It can be difficult, however, to know whether all infested wood has been removed.
