What does insufficient ventilation in crawl space lead to?

Insufficient ventilation in a crawl space can lead to moisture accumulation, which creates an environment that is particularly favorable for termites and other wood-destroying organisms. Limited airflow prevents the area from drying out, allowing humidity levels to rise. This moist environment is ideal for termite activity because these pests thrive in damp conditions where they can easily access the cellulose in wood. Over time, the accumulation of moisture can lead not only to infestations of termites but also to other structural issues such as decay and mold growth. Proper ventilation is crucial to manage moisture levels and protect against these potential threats to wooden structures.
