International Compliance Association (ICA) Home Inspector Practice Exam

Which of the following pests is considered the most destructive during a home inspection?

1. Carpenter ant

2. Subterranean termite

3. Drywood termite

4. Formosan termite

The correct answer is: Formosan termite

The Formosan termite is regarded as the most destructive pest during a home inspection due to its aggressive consumption of wood and its ability to thrive in various environmental conditions. Unlike other termite species, Formosan termites can form large colonies with populations that can number in the millions. This enables them to cause significant and rapid damage to wooden structures, often going unnoticed until severe structural damage has occurred. Additionally, their ability to build mud tubes and their propensity to invade homes and buildings more readily than other pests contribute to their destructive reputation. Home inspectors need to be particularly vigilant for signs of Formosan termite activity, as the damage they inflict can become extensive very quickly, making early detection crucial for homeowners and property managers.
