Accomac, Virginia – October 12, 2026 -- Homeowners in coastal Virginia can cut down on termites, ants, and rodents by sealing the crawl space beneath their house, according to a HelloNation article featuring Clay Morgan of Charles E Morgan & Sons Inc. in Accomack County.
Moisture is what draws pests under the house
Humid weather and damp soil in communities such as Onancock create conditions that attract insects and rodents, the article explains. Unsealed crawl spaces often supply the moisture, shelter, and access pests need. Termites, ants, and rodents can get in through foundation gaps, open vents, or damaged barriers.
Encapsulation combines three steps
The process includes installing vapor barriers, sealing openings, and managing humidity. Together, these steps separate the crawl space from damp soil and outdoor air. A drier space is less attractive to pests and helps protect wooden supports and other structural materials.
Humidity management may be needed year-round to keep conditions suitable.
Coastal weather keeps vented crawl spaces damp
For homeowners in Onancock and Cape Charles, high humidity, frequent storms, and changing groundwater can leave traditional vented crawl spaces wet. Over time, the article says, this can contribute to pest activity, musty odors, and deterioration of building materials.
Crawl space air can reach living areas
Air from beneath a home can rise into living spaces through the stack effect. If the crawl space holds excess moisture, mold, or mildew, that airflow may add to odors and indoor humidity problems. A properly maintained crawl space may reduce moisture-related damage and improve indoor comfort.
Encapsulation does not replace pest control
The article stresses that sealing is not a substitute for every pest treatment. Existing infestations may still need professional pest control. Homeowners should identify moisture problems before sealing begins, including water intrusion, drainage concerns, and damaged materials.
Simply covering exposed soil is not enough, the article says. Storms and groundwater can introduce moisture beneath foundations, so proper installation and ongoing maintenance are needed to preserve the benefits. It recommends combining moisture management, sealed entry points, and regular inspections.
