OPM Termite Practice Exam

Which of the following conditions is NOT considered conducive to wood-destroying organisms?

1. Faulty grade

2. Earth to wood contact

3. Regular exposure to sunlight

4. Wood debris near structure

The correct answer is: Regular exposure to sunlight

Regular exposure to sunlight is not considered conducive to wood-destroying organisms. Sunlight is an important factor in maintaining a dry environment, as it helps to reduce moisture levels in wood materials. Wood-destroying organisms, such as termites and wood-decaying fungi, thrive in moist, dark environments. Therefore, direct sunlight can act as a natural deterrent to their activity by limiting the conditions under which they can survive and reproduce. In contrast, conditions such as faulty grading, earth to wood contact, and wood debris near structures create moist and sheltered environments that are conducive to such organisms. Faulty grading may lead to water accumulation near the foundation, promoting dampness. Earth to wood contact can allow moisture to transfer from the soil to the wood, making it an ideal habitat for pests. Similarly, wood debris provides both moisture and a food source for wood-destroying organisms, increasing the likelihood of an infestation.
