Wood Destroying Organism (WDO) Home Inspection Practice Exam

Why is it important to eliminate areas where soil makes contact with wood?

1. To promote insulation

2. To reduce pest attraction

3. To enhance drainage

4. To increase structural integrity

The correct answer is: To reduce pest attraction

Eliminating areas where soil makes contact with wood is crucial primarily to reduce pest attraction. Wood that is in direct contact with soil creates a conducive environment for wood-destroying organisms such as termites and certain types of fungi. These pests often thrive in damp and dark conditions found in soil, making it easier for them to access and potentially damage the wooden structures of a home. By keeping wood elevated above soil and providing barriers, the likelihood of pest infestation diminishes significantly. This preventative measure not only helps to protect the structural integrity of the wood but also reduces the overall need for pest control interventions in the future. Understanding the relationship between soil contact and pest attraction is vital for maintaining the health of a home's foundation and preventing costly repairs.
