Termites do not fully stop working in winter, even though their activity can slow down depending on the temperature and where the colony is located. In Plano, where winters are generally mild with occasional cold snaps, termites often remain active underground or within heated structures throughout the year.

Subterranean termites, the most common species in North Texas, can continue feeding and causing damage inside a warm home even when outdoor temperatures drop, since indoor conditions rarely match the cold seen outside.

Below, we take a closer look at how winter weather actually affects termite behavior, why homes stay vulnerable during cooler months, and what Plano homeowners should watch for as the seasons change.

How Cold Weather Affects Termite Activity

Termite behavior is closely tied to temperature, but the relationship is more complicated than simply stopping when it gets cold outside.

Underground activity continues. Subterranean termites live in soil, often several feet below the surface, where temperatures remain more stable than the air above ground. This means colonies can stay active through much of the winter, even during a cold snap.

Indoor conditions rarely change. Once termites have found their way into a structure, the temperature inside a home stays consistent regardless of the season. Heated homes provide the same favorable conditions for termites in January as they do in July.

Activity may slow, not stop. Colder outdoor temperatures can reduce above-ground termite activity, such as swarming, but this does not mean the colony becomes inactive. Feeding and tunneling can continue at a slower pace rather than stopping altogether.

Swarming season still applies. Termite swarms in North Texas typically occur in spring, but this is tied to temperature and moisture patterns rather than a full winter shutdown. Colonies remain present and active throughout the colder months leading up to swarming season.

Why Plano Homes Stay at Risk During Winter

Plano's climate includes mild winters with occasional freezes, which means the ground rarely stays cold long enough to fully halt termite activity below the surface. Combined with heated homes that offer a stable environment year round, this creates ongoing conditions where termites can continue causing damage without producing obvious signs.

Because termite damage often develops slowly and out of sight, many homeowners do not realize an infestation exists until the damage has already progressed. Winter is not a season to relax termite prevention efforts, even though visible activity like swarming may not be present.

Signs of Termite Activity to Watch for in Winter

Even during cooler months, certain signs can indicate termite presence:

Mud tubes. These pencil-sized tunnels, often found along foundations, crawl spaces, or exterior walls, are one of the clearest indicators of subterranean termite activity.

Hollow-sounding wood. Wood damaged by termites often sounds hollow when tapped, since termites feed from the inside out.

Sagging floors or ceilings. Structural damage from long-term termite feeding can lead to noticeable sagging in floors, ceilings, or door frames.

Discarded wings. Even outside of peak swarming season, finding discarded termite wings near windowsills or foundations can be a sign of nearby colony activity.

Frass. Certain termite species leave behind small, wood-colored droppings that resemble sawdust, often found near baseboards or window frames.

What Homeowners Can Do During Winter Months

1. Schedule an inspection. A termite inspection during winter can catch signs of activity that might otherwise go unnoticed until spring.
2. Check crawl spaces and foundations. Regularly looking for mud tubes or moisture buildup near the foundation can help identify early warning signs.
3. Address moisture issues. Termites are drawn to moisture, so fixing leaks, improving drainage, and ventilating crawl spaces can reduce conditions that attract them.
4. Store firewood away from the home. Firewood piles near the house can give termites an easy path indoors, especially during colder months when firewood use increases.
5. Maintain ongoing protection. Because termite activity does not fully pause in winter, ongoing monitoring and treatment programs offer more consistent protection than addressing the issue only when damage becomes visible.
