False Powder Post Beetle Infestation

With the obvious exception of termites, wood boring insects, such as false powder post beetles cause most of the wood damage in homes. While some powder post beetle damage can be a cause for concern, some evidence of powder post beetle damage may be an old infestation where the insects have died.

Most powder post beetles can go unnoticed for long periods of time in homes. Some species infest only hardwoods but most infest hardwoods and softwoods as well. Death watch beetles will take advantage of moist wood conditions to infest crawlspaces, wood siding and other moisture-prone wood.

False powder post beetles can be easier to detect, than other types of powder post beetles, as adult females dig tunnels in wood to lay their eggs, unlike most powder post beetles who lay their eggs in tiny cracks and crevices in wood, leaving no indication of an infestation until the pupae emerge at the wood’s surface, leaving tiny exit holes and “frass,” small piles of powdery sawdust.

Powder post larvae, also known as woodworms feed on wood as they develop through their pupae states into adulthood, emerging from the wood in the spring through September. Homeowners, suspecting false powder post beetle activity, are advised to contact a professional pest control company to identify wood boring insects and formulate a plan to eliminate powder post beetles from your home.
