Which conditions are likely to cause a subterranean termite problem?

The correct answer pertains to faulty grading, which can lead to conditions that promote subterranean termite infestations. Subterranean termites thrive in environments where moisture is abundant, as they require a damp area to survive and reproduce. When the grading around a property is inadequate or faulty, it can create areas where water accumulates, leading to soil saturation and creating an ideal habitat for these pests.

Excess moisture in poorly drained areas can enhance the presence of wood-to-soil contact and organic material, both of which are attractive to subterranean termites. By ensuring proper grading, homeowners can help manage water runoff and reduce the risk of termite problems by keeping moisture levels lower and preventing conducive conditions.

The other conditions mentioned, such as well-drained soil, high winds, and cold temperatures, generally do not support the survival and reproduction of subterranean termites. Well-drained soil would assist in keeping the areas around a home dry, which is unfavorable for termites. High winds may not have a direct impact on the termite population, and cold temperatures typically limit their activity, as subterranean termites prefer warmer, moist environments.
