Termites remain active year round, even during the winter. In cooler climates, subterranean termites typically move deeper into the ground during the cold season to access the warmth they need to survive. While subterranean workers will forage closer to their nests during the winter, they will remain active (although likely not quite as active as during warmer months).
Finding termites in the winter time inside your home is possible. Subterranean and drywood termites that have found shelter and food in your home’s foundation and walls will not be as affected by cold outdoor temperatures.
While most termites remain active during the winter, it is unlikely that you will see swarming termites between December and February, except in more tropical areas of the country like Florida where temperatures inside or outside homes can reach 70 degrees or higher. In more northern parts of the country, you may see other signs of termites in the winter, such as mud tubes or damaged wood.
Trained termite inspectors can inspect your home and identify active or previously active colonies any time of the year. Contact your termite expert if you see signs of an infestation.
