Wood Destroying Organism (WDO) Home Inspection Practice Exam

What is a common sign of termite infestation?

1. Wet wood

2. Crumbling foundation

3. Tiny holes in wood

4. Faint scratch marks

The correct answer is: Tiny holes in wood

A common sign of termite infestation is the presence of tiny holes in wood. These holes, often referred to as "exit holes," are created by termites as they tunnel through the wood, which is their primary food source. Termites consume the cellulose in wood, and as they forage and create pathways, they leave behind these small openings that may also be surrounded by frass, which is their fecal matter. The identification of tiny holes in wood is crucial for recognizing a termite problem early. It is an indication of active feeding and, if left unchecked, can lead to significant structural damage. Because termites can silently compromise the integrity of wooden structures over time, spotting these signs early can help homeowners take prompt action to mitigate further damage and address the infestation effectively. While wet wood may suggest other issues such as water damage or mold growth, it is not exclusive to termite activity. Crumbling foundations could stem from a variety of structural concerns and do not specifically indicate termite presence. Faint scratch marks may suggest other pests but are not definitive signs of termites. Thus, recognizing tiny holes in wood is key to diagnosing a termite infestation accurately.
