As the cold weather sets in, many homeowners may mistakenly believe that termites are no longer a concern. However, termites remain active year-round, and winter can be a critical time for infestations. Staying vigilant for signs of termites during the winter is essential for maintaining the structural integrity of your home. In this comprehensive guide, we will explore the importance of monitoring for termite activity during colder months, identify common signs of infestation, and provide effective strategies for prevention and control.

Why Termite Vigilance is Crucial in Winter

Subterranean and Drywood Termites

There are two main types of termites that can infest homes: subterranean and drywood termites. Subterranean termites, which live in the soil, remain active in winter, particularly in heated homes where the temperature is conducive to their survival. Drywood termites, found in wood structures, can also continue to cause damage during this season.

The Risk of Undetected Damage

Termite infestations can go unnoticed during winter, leading to significant damage by the time they are detected. Understanding the signs of termite activity is crucial for early detection and control.

Identifying Termite Signs in Winter

Mud Tubes

Subterranean termites create mud tubes for protection while they travel. These pencil-sized tubes can often be found along foundations, walls, and other entry points.

Wood Damage

Termite-infested wood may appear hollowed out, with a honeycomb interior. Tap on suspect areas; a hollow sound can indicate termite damage.

Termite Droppings

Drywood termites leave behind droppings or frass, which resemble tiny, ridged, wood-colored pellets. Finding these droppings can be a clear sign of infestation.


Although less common in winter, termite swarms can occur, particularly in heated buildings. Swarmers, or winged termites, are often the first visible sign of an infestation.

Preventative Measures

Regular Inspections

Schedule professional termite inspections annually, even during winter, to catch infestations early.

Reduce Moisture

Termites are attracted to moisture. Fix leaks, ensure proper drainage, and use dehumidifiers in damp areas of your home.

Remove Food Sources

Keep firewood, mulch, and other cellulose-based materials away from your home’s foundation.

Termites can be a year-round threat, and winter is no exception. By understanding the signs of termite activity and taking proactive measures, you can protect your home from costly damage. Stay diligent and consult with pest control professionals for the best prevention and treatment strategies.
