We’re often asked whether termites are active in the winter. Despite the cooler temperatures, termites remain active in Fairfax VA and across Northern Virginia throughout the winter months.
Termites are active and can do damage across Northern Virginia all year long.
Subterranean termites, which are common in Northern Virginia, Washington, D.C. and suburban Maryland, typically move deeper into the ground to stay warm. Subterranean workers, the small white termites commonly seen in homes and other infested wood, continue to forage and feed the colony, but stay closer to the nest.
Termites can and are often found inside homes during the cold winter months. Your home’s heated walls, foundation and insulation help protect termites from the cold, and allow them to continue to forage in your wood.
Subterranean termite nests can be 18 inches below ground surface. The subsurface ground temperature provides the perfect protection from the cold winter. Meanwhile, the controlled temperature inside your basement provides the perfect conditions for termites to continue to forage for food and damage wooden structures.
It’s unusual to see swarming termites during these winter months. Termites swarm in Northern Virginia in late spring and early summer when temperatures are warmer.
It can take two to four years for a termite colony to mature. During this time, termites and thousands of dollars in damage can go undetected.
Trained and certified termite inspectors can inspect your home to identify and eliminate termite problems before they become serious. Signs of termite activity and damage, even in the winter, include mud tubes and tunnels, moisture problems, wood rot and damaged wood. Annual termite inspections and warranties are a smart way to protect your home and head off problems.
