Powder Post Beetles are found in a variety of wood products. They infest everything from wicker baskets to hardwood floors and pianos. They are usually detected by seeing very fine saw dust or little holes in wood surfaces. The holes are the openings through which the adult beetles emerge.
Powderpost beetles prefer the sapwood of oak and other hardwoods and many of the insects will continue to breed in an infested piece of wood for generations. This practice can result in an ultimate destruction of the wood.
