Recently, we were selling a home and the home inspector noted a powder post beetle pest infestation. If you have any wood structures with tiny holes (like tiny dart holes) sprinkled throughout your structure you may have a Powder post beetle infestation. These little bugs drill holes in the wood and hang out. After many years of active infestation, decay with the wood could lead to structural integrity issues. It’s important to kill these bugs.
How do you know if you have Powder Post beetles?
Other than many tiny holes you can also check for recent sawdust. If active, these bugs will leave small piles of saw dust around infestation areas. When they dig into the wood they leave a trail. Typically, they live inside the wood and can be difficult to see. Also, these bugs cannot live in cold temperatures. A couple days of sub zero temperatures and they die off. However, if the infestation area is heated they can remain alive and live through winter. They are most active in the Spring /Summer and this is the best time to treat. A local pesticide company can spray the wood and it kills the bugs.
