What indicates a power post beetle infestation?

The presence of shot holes and white powdery frass is a clear indication of a powder post beetle infestation. Powder post beetles are known for creating small exit holes as they emerge from the wood, which can appear as small "shot holes." This characteristic is an important sign that allows inspectors to identify the specific type of beetle infestation.

Additionally, the frass, which is a type of sawdust produced by the beetles as they feed on the wood, may present as a fine, powdery substance. The white coloration of this frass can particularly help distinguish it from other wood-destroying pests. These signs are key for professionals conducting inspections, as they help determine the type of insect causing the damage and the necessary steps for treatment.

The other options may indicate different types of wood damage or infestations but do not specifically point to a powder post beetle. For example, frass and mud tubes are commonly associated with termites, while visible dead beetles can result from various pests. Wood that sounds hollow may suggest a range of wood-destroying organisms but does not provide the specific characteristics of a powder post beetle infestation.
