Are Termites Active in Winter? Exploring Termite Behavior During the Colder Months

If you’re a homeowner, you may be wondering whether termites are active in the winter. While it’s true that termites remain active during winter, the level of activity depends on several factors. In this article, we’ll explore termite behavior in different seasons, the types of termites and their winter activity, and the signs of winter termite infestation.

Termites are active in all seasons, but their behavior varies depending on the temperature and humidity levels. In winter, termites experience a decrease in activity, but a well-established colony that can maintain a moist connection to the soil will see no decrease in activity. However, termites are less likely to colonize your home in winter months.

Understanding termite activity in winter is essential for homeowners looking to protect their property from termite infestation. In the following sections, we’ll take a closer look at the different types of termites and their winter activity, signs of winter termite infestation, and ways to prevent termite infestation during the winter months.

Key Takeaways

  • Termites remain active in the winter, but their activity levels depend on several factors.
  • The ideal temperature for all species of termite is 75 degrees Fahrenheit.
  • Understanding termite behavior in different seasons is essential for preventing termite infestation.

Termite Behavior in Different Seasons

Summer and Fall Activity

During the summer and fall months, termites are highly active. They thrive in warm and humid climates, and this is when they do the most damage to homes and buildings. Termites are active during the day and night, and they are constantly searching for sources of food and moisture. They build mud tubes to travel between their nests and food sources, and they can quickly cause extensive damage to wooden structures.

Winter Activity

Contrary to popular belief, termites do not hibernate during the winter months. They remain active year-round, even during the colder winter months. However, their behavior does change somewhat during this time. Termites will burrow deeper into the ground to find warmth and moisture, and they will slow down their activity levels. They may also build mud tubes closer to the ground to reduce exposure to the cold air.

It’s important to note that while termites may slow down their activity during the winter months, they are still capable of causing damage to your home. If you live in an area with a warm climate year-round, termites may remain just as active during the winter months as they are during the summer.

In areas with cold temperatures, termites may be less active during the winter, but they can still survive. They will simply adjust their behavior to the colder weather conditions. For example, they may build their nests deeper underground to stay warm, or they may focus on consuming non-wood materials, such as insulation or drywall.

Overall, it’s important to remain vigilant for signs of termite activity throughout the year, regardless of the season. Regular inspections by a professional pest control company can help identify any potential termite problems before they cause serious damage to your home.

Types of Termites and Their Winter Activity

When it comes to termites, there are three primary types that you need to be aware of: subterranean termites, drywood termites, and Formosan subterranean termites. Each of these types has unique characteristics that impact their winter activity.

Subterranean Termites

Subterranean termites are the most common type of termite and are found throughout the United States. These termites live in the soil and create mud tubes to travel between their nests and food sources. In the winter, subterranean termites remain active, but their activity may slow down due to the colder temperatures. However, if the temperature inside a home remains warm enough, subterranean termites can continue to feed and cause damage throughout the winter.

Drywood Termites

Drywood termites are less common than subterranean termites and do not require soil to survive. Instead, they live directly in the wood they are feeding on. In the winter, drywood termites may become less active due to the colder temperatures, but they can still cause damage if they are present in a home. Unlike subterranean termites, drywood termites do not create mud tubes, so their presence may be more difficult to detect.

Formosan Subterranean Termites

Formosan subterranean termites are a particularly aggressive type of termite that can cause significant damage to homes and other buildings. These termites are most commonly found in the southern United States and live in the soil, creating mud tubes to travel between their nests and food sources. In the winter, Formosan subterranean termites remain active, but their activity may slow down due to the colder temperatures.

Overall, while the winter may impact termite activity, it does not necessarily mean that termites will die off or stop causing damage. It is important to remain vigilant and watch for signs of termite activity, such as mud tubes, nests, or damage to wood in your home. If you suspect that you have a termite infestation, it is important to contact a pest control professional as soon as possible to prevent further damage.

Signs of Winter Termite Infestation

If you suspect that you have a termite infestation in your home during the winter months, there are several signs you can look out for. Here are some of the most common signs of winter termite infestation:

  • Discarded Wings: One of the most obvious signs of termite activity is the presence of discarded wings. During the winter months, termites will often swarm and mate, leaving behind piles of wings as evidence of their activity.

  • Mud Tubes: Termites build mud tubes to travel between their nests and food sources. These tubes are typically found along the foundation of your home or in crawl spaces. Even if you don’t see active termites, the presence of mud tubes is a clear indication that they are nearby.

  • Wood Damage: Termites feed on wood, so if you notice any signs of wood damage in your home, it could be a sign of termite activity. Look for hollowed-out wood, sagging floors, or buckling walls.

  • Droppings: Termite droppings, also known as frass, look like small piles of sawdust. If you notice any piles of frass around your home, it could be a sign of a termite infestation.

  • Swarmers: During the winter months, you may see termite swarmers flying around your home. These are the reproductive termites that are looking to mate and start new colonies.

  • Ants: Ants and termites are often mistaken for each other, but they have different habits and behaviors. If you see ants in your home during the winter months, it could be a sign of a termite infestation, as they often share the same habitat.

If you suspect that you have a termite infestation in your home during the winter months, it’s important to have a professional termite inspection as soon as possible. A trained inspector can identify the extent of the infestation and recommend the best course of action to eliminate the problem. Remember, termites are destructive insects that can cause significant damage to your home if left unchecked, so it’s important to act quickly.


In conclusion, termites are active during the winter season, but their behavior changes depending on their species and location. While subterranean termites move deeper into the ground to access warmth, drywood termites stay active and continue to feed on wood.

As a homeowner or property owner, it’s important to be aware of the signs of termite activity, regardless of the season. Look for mud tubes on the foundation or walls, damaged wood, and discarded wings. Regular inspections by a professional can also help detect and prevent termite infestations.

If you live in a location with high termite activity, such as Florida, it’s crucial to take preventative measures to protect your home. This can include using termite-resistant building materials, maintaining proper ventilation and insulation, and keeping the area around your home free of debris and standing water.

While termites can be a serious problem for homeowners, it’s important to remember that not all termites are the same. Some species, such as dampwood termites, are less destructive and may not require treatment. It’s important to consult with a professional to determine the best course of action for your specific situation.

Overall, understanding the behavior and habits of termites can help you take proactive steps to protect your home from termite damage. By staying informed and taking preventative measures, you can help ensure that your home remains termite-free and protected for years to come.
