Which practice can help homeowners reduce their risk of termite infestations?

Maintaining proper ventilation in crawl spaces and attics significantly reduces the risk of termite infestations because it helps keep these areas dry and less conducive to the moisture that termites require for survival. Termites thrive in damp environments, so ensuring adequate airflow and low humidity levels inhibits their ability to establish colonies in these spaces. This practice also aids in preventing wood decay, which can attract termites looking for food sources. Proper ventilation is a proactive measure that can significantly diminish the likelihood of a termite problem developing within the home.

Other options may not effectively target the conditions that attract termites or could inadvertently contribute to favorable conditions for them. For instance, chemical repellents may create only a temporary barrier without addressing underlying factors like moisture, while regularly watering the garden could increase humidity around the home. Covering the soil with plastic sheets might trap moisture beneath, potentially creating a favorable environment for termite activity.
