Wood Destroying Organism (WDO) Home Inspection Practice Exam

How can homeowners reduce attacks by carpenter bees?

1. Using stainless steel fasteners

2. Paining exposed wood surfaces with oil-based paint

3. Installing plastic sheets over wooden surfaces

4. Applying a water-based paint

The correct answer is: Paining exposed wood surfaces with oil-based paint

To effectively reduce attacks by carpenter bees, painting exposed wood surfaces with oil-based paint is particularly beneficial. Carpenter bees are attracted to untreated wood surfaces, where they create nests by boring holes. Oil-based paints create a protective barrier that makes the wood less appealing for nesting. The oil-based formulation penetrates the wood better than some other types of finishes, providing a longer-lasting and more durable shield against these pests. In contrast, while stainless steel fasteners (like those in the first option) may help in some instances by preventing structural damage from other wood-destroying organisms, they do not specifically deter carpenter bees. The use of plastic sheets over wooden surfaces might not provide a practical or effective solution for common exposure and could potentially create moisture problems. Water-based paints, while environmentally friendly and user-friendly, do not provide the same level of protection and longevity against carpenter bee infestations as oil-based paints do. Therefore, using oil-based paint is a proactive strategy for homeowners looking to safeguard their wooden structures from carpenter bees.
