Wood Destroying Organism (WDO) Home Inspection Practice Exam

Which wood-destroying organism primarily affects hardwood structures?

1. Termites

2. Carpenter ants

3. Powderpost beetles

4. Wood borers

The correct answer is: Powderpost beetles

The correct choice focuses on the powderpost beetles, which are specifically known for their destructive impact on hardwoods. These insects are adept at infesting and damaging wood products, especially those with a high starch content, such as oak, ash, and hickory. Once they invade, they lay eggs in the wood, and the larvae then consume the wood as they develop, leading to structural damage that can compromise the integrity of hardwood construction. While termites can also affect wooden structures, including hardwoods, they are more commonly associated with softwoods. Carpenter ants tend to nest in wood but do not consume the wood in the same way; they remove wood to create tunnels. Wood borers is a more general term that could refer to multiple organisms, but it does not specifically highlight a group that primarily targets hardwood. Thus, powderpost beetles are distinct in their association with hardwoods, making this option the most appropriate in relation to the question.
