Are Termites Active During Winter?

“Oh, the weather outside is frightful, but the fire is so delightful, and since we’ve no place to go” … it looks like we’ll be stuck inside with the termites. 

Just because it is cold outside, and you want to be inside, doesn’t mean that you are the only one that feels that way. Termites, and other pests, also seek shelter from the cold of winter.

Termites appear to be most active in summer because humans are most active then. We humans tend to notice termites, and termite damage, because when it is nice outside, we move around more, cleaning, doing chores and yard work.

Termites are colonizing insects like bees and ants. Each type of termite plays a specific role within the colony. Termite workers are responsible for gathering food for the colony and are the ones which cause the most damage to wood and your property. Workers are also the one’s you see in the soil around the foundation of your property.

Unfortunately, termites defy the seasons, and our desires, by staying active year-round. Regardless of the weather, the time of year, or your location, termites don’t take time off because it is cold. Termites will invade your home in the dead of winter AND the hot days of summer.

Winter termite activity: Outdoors

Not all insects die off or go into hibernation during the winter months. Insects and pests have all sorts of survival strategies to make it through the cold.

In colder climates, winter does reduce termite activity. Unfortunately, cold conditions won’t kill termites or drive them away. It just forces them deeper underground or into the center of wood sources that they find outside. This makes the heat coming from inside your home that much more appealing.

Subterranean termites build their colonies underground. In winter months, they try and stay underground below the frost line. The colder the weather, the deeper they’ll dig in search of warmer ground.

Drywood and dampwood termites colonize in wood filled areas like old stumps or trees. If you have stored firewood outside, that wood is vulnerable to termites as well. Once you bring that wood into the house you may have inadvertently introduced termites as well. It’s important that you remove stumps and dead trees and keep firewood at least 20 feet away from the side of the house.

Winter termite activity: Indoors

Termites don’t typically find and move into your home during the winter months. Usually, they were already in your house to begin with. While the colder temperatures make outside habitation less inviting, termites will stay where they are provided with a nice, temperate, springtime temperature; your home.

The ideal temperature for termite development (and damage) is around 75°F, a comfortable temperature for any home during winter. But don’t drop that thermostat to 50 thinking they’ll go away. That won’t work. Your home is the perfect winter getaway for termites because they get wood, water and warmth. You’ll be hard pressed to scare any termite from your home with these excellent accommodations.

Do termites swarm in winter?

When a colony matures it sends out swarmers to create new colonies. This activity usually coincides with warmer months. Just because your house might be a consistent temperature doesn’t mean you’ll end up with a swarm in your home.

In spring, when it gets warmer outside the walls of your home, it will bring the temperatures up enough to trigger the swarming behavior. That’s usually when you find swarmers crawling around on your interior walls.

Swarming termites can take flight in you home if they’ve infested an interior wall, but it is rare. Regardless of whether they are inside or out, most swarming activity takes place during warmer months of the year.

Termite Prevention

Small steps make a big difference in termite prevention and sustaining an effective termite treatment plan. Start by eliminating moisture conditions and termite food around your home. These simple steps make your home a less attractive target, helping deter termites.

Termites do leave warning signs. Indicators of a termite infestation include wood that sounds hollow when tapped, cracked or bubbling paint, mud tubes on exterior walls or crawl spaces, and a temporary swarm of winged insects in or around your home.

Simple steps can help prevent an infestation. Keep gutters and downspouts free of debris, install screens on exterior vents, store firewood and lumber away from your home, and eliminate moisture by fixing pipes and other home fixtures prone to leaking.

What do termites eat?

This is not a trick question, but it might feel like one. The answer is wood, right? Termites eat wood! Technically, that is correct, but it isn’t the wood they are after. It is a byproduct of the wood called cellulose.

Termites eat wood to get to the cellulose and nutrients they need to live. Termites don’t digest the wood they eat. Instead, there are microorganisms living inside the termite’s digestive system called protozoa that do the heavy lifting.

The protozoa break down the wood to expose the cellulose thus creating a digestible product for the termite. The protozoa turn’s the cellulose fibers into a wholesome meal and gives termites access to a food source that’s largely ignored by other species.

What is cellulose?

Cellulose is the most plentiful organic compound on the planet. It is the organic substance which gives structure to wood, plants, and grass.

Cellulose is made of sugar molecules linked together to form a chain-like pattern. Wood is made up of mostly cellulose, and this is what termites ingest when they feed on wood.

What types of wood do termites eat?

Different species of termites eat different types of wood. In Fredericksburg, Virginia, the most common type of termite is the Subterranean termite.

termites sigma pest control

Subterranean Termites

These termites prefer moist, underground conditions and soft wood. Wood damaged by ground moisture makes for easier eating and living underground provides them with shelter from predators.


Drywood Termites

These termites prefer the wood used in your home's framing, structural timbers, hardwood floors and furniture. Unlike their subterranean cousin, drywood termites inhabit the wood directly and not the soil.


Dampwood Termites

These termites feast on the wood found in decaying logs, stumps and wood piles. These conditions are NOT normally associated with your home, but if given the chance, and the proper conditions, dampwood termites will come knocking.

Other things termites have been known to eat:

– particle board, sheetrock, plywood.

What types of wood will termites NOT eat?

Termites don’t eat ALL types of wood. There are some they’ll steer clear of. Some wood, like cedar and redwood, is naturally resistant to termites. Remember, termites like decaying and rotted wood, while cedar and redwood are resistant to decay. 

Pressure-treated wood is another termite resistant wood. Pressure treated wood embeds preservative chemicals into the wood, thus creating a chemical barrier that resists termites and decay. 

Plastic composite materials are also resistant to insects and they don’t rot. The use of waste wood fiber and plastic creates a material used in construction that is impervious to insects.

Other notes:

  • Termites will not eat through paint, but they may eventually find a way to get to the unpainted part of the wood.
  • Termites normally to not eat live trees or bushes because they prefer decayed or dying wood.

What should you do if you have termites?

If you see the signs of termites already in your home, you may have a problem which needs to be handled by a trained professional.

If left untreated, termites can seriously weaken the wood within your home (floors, walls, joists, timbers, frames) leading to possible collapse and costly repairs. Every home with a wood structure should be actively protected from termites.

Subterranean Termite: behavior, habitat and diet

There are over 45 different kinds of termite species found in North America and are categorized into one of three termite groups – subterranean, dampwood or drywood.

Each termite group has unique environmental requirements and behaviors that determines whether or not they live in soil and where they construct their colonies.

Termites create more harm to our economy than any other pest. They cause billions of dollars in damage to homes, businesses, and historical structures every year. termite

Subterranean termites have been around for more than 55 million years and in that time have become quite proficient at what they do; eat wood.

To survive on this planet for as long as they have, they’d need some significant support and protection. A great deal of their success and survival can be attributed to their loyalty to the colony. Subterranean termites are social insects. They live in family groups called colonies, working together to build the perfect home.

Subterranean termites also need a constant supply of moisture (found in soil), food (cellulose), and privacy which they create in the form of mud tubes.

Behavior, diet and habitat are the ‘keys to success’ for the subterranean termite and we’ll show you just how they do it and what to look for.

Termite Behavior

During the spring months (March-May) winged termites, also known as swarmers, emerge from their hiding place (the soil, your home) and take to the skies to seek out new places to colonize.

Swarmers are termite kinds and queens that have left the colony in search of a new place to start a family. Often thought to be flying ants, the swarmers pair up during their flight, land together, discard their wings, and being a new life.

This swarming process is a telltale sign that you have a termite problem. Even if you don’t see them fly, you might still see their discarded wings cluttered upon the ground. Once they lose their wings, they tunnel into the soil, seal the entrance, and spend the rest of their lives underground.

Within a few days of mating, the queen will produce her first batch of eggs. As the queen produces more eggs, the older offspring tend to the younger siblings, and the colony grows from there. The original king and queen enjoy the longest lifespan within the colony and live for a decade or longer.

Termite Habitat

Privacy to termites means staying enclosed. Workers and soldiers do not have eyes so they can’t see if you are looking at them, however they obviously sense light and want to block it out because an opening represents loss of humidity and the opportunity for invasion from their mortal enemy — ants.

Subterranean termites build their colonies in the soil and construct pathways in the ground that are used to locate sources of wood that remain below ground or on the ground surface.

Wood located above ground, such as the wooden construction components of a house, are reached by termite workers moving through earthen tunnels called mud tubes that connect above ground wood with the soil.

Termite Diet

The subterranean termite eats cellulose by way of a specialized stomach that breaks down the fiber. Termites rely primarily upon bacteria and other microbes in their guts to digest the cellulose for them, allowing them to absorb the end products for their own use. termites

The fact that domestic termites consume cellulose-based products such as wood is beneficial in the wild. When a tree falls and begins to decay, termites can move into the area and consume the dead wood. The result is a composting affect that enrichs the soil from the breaking down of wood products.

It is not known exactly how subterranean termites locate sources of food, but it is a common belief that they divide up the territory around the nest and start digging a network of tunnels. As they dig, they encounter buried wood in the process and alert other termites to the source. 

Termites eat cellulose material including the following:

  • wood
  • plants
  • carpet
  • insulation
  • cardboard
  • sheetrock paper
  • fabric
  • animal feces


Termites are able to live off cellulose thanks to the organisms found in their stomachs. A mixture of bacteria and protozoa produce a special enzyme that breaks down cellulose. The result is a form of sugar that provides nutrition for the pests to survive.

Younger termites aren’t developed enough to breakdown the cellulose, so they rely on the older members of the colony to pass long the sugar like substance.termites

Subterranean termites like to eat the soft fibers of springwood and leave the harder summerwood behind. Wood eaten by subterranean termites resembles a honeycomb, and many of its galleries contain dirt and fecal particles.

What types of Termites live in Fredericksburg?

Over 2,000 species of termites exist around the world. Lucky for us, we only have to worry about ONE type of termite – the Eastern Reticulating Subterranean Termite.

Termites are known as the ‘silent killers’ because they are able to chew through wood undetected. As the ground warms, termites spring into action with the scout crew (a.k.a. Swarmers) the first to emerge from their winters nap, in search of new territory to harvest.

Swarmers have wings, and they fly, and are often mistaken for winged ants. But make no mistake about it, you need to know the difference between a flying ant and a termite before it is too late. 

Each year, termites cause roughly $5 billion in property damage. To help you identify these pests, we’ve created the following handy-dandy field guide.

Subterranean Termite

termitesSubterranean termites often form large colonies and eat rapidly through wood, making them the most destructive termites. These pests live in the soil beneath and around homes and often enter through wood that touches the ground or by constructing mud tubes from the ground to the wood they infest. Cracks in concrete walls and foundations made of hollow blocks are also paths these insects could take to infest a house.

What do they look like?

Termites live according to a caste system. There are three main types of termites in the subterranean termite caste: workers, soldiers, and swarmers. Each has a specific job in support of the colony, and each is uniquely equipped with the tools they need to get the job done.

termitesWorkers are the smallest of the three types, measuring one-eighth to three-eighths of an inch in length. They are opaque, almost translucent, and they separate wood from it’s source. They live their entire lives in dark tunnels, both above and below ground. Because they are in the dark their entire lives they do not have eyes. Despite not having eyes, workers can sense the difference between light and dark. They know they are in danger of predators if exposed to light.

termiteSoldiers are as long as workers, but have larger heads with powerful mandibles. The role of the soldier is to protect the colony from predators.

termite wingsSwarmers have wings and can fly. they are coal black to pale yellow, flattened, and about 3/8th inch long. They leave a mature colony to mate and establish new colonies. They eventually become the king and queen in new colonies. Unlike soldiers and workers, swarmers have eyes which allows them to leave the dark tunnels of the nest.

Facts about subterranean termites

  • The king and queen can produce 3600 eggs per day.
  • The main portion of their nest underground and can have upwards of 2 million residents.
  • They make mud tubes to access structures and avoid daylight.
  • Termite colonies eat 24 hours a day, 365 days a year.
  • The need contact with soil to survive.

Prevention tips

  • Avoid water accumulation near your home’s foundation. Divert water away from the home or property by using downspouts, gutters and splash blocks. Be sure these devices are working properly and not blocked or clogged.
  • Reduce humidity in crawl spaces with proper ventilation.
  • Remove wood and waste lumber from the yard, and never bury wood.
  • Eliminate wood contact with the soil.

What to do if you have Termites?

Out of sight doesn’t always mean out of mind, especially when it comes to termites. Termites will cause serious damage to your property if you allow them to go unchecked. The cost of repairing this damage can expensive, and the longer the termites have access to your home or business the more damage they’ll do.

That is why it is important to explore your termite treatment options as soon as possible in order to reduce the risk of damage to your home. Contact Sigma Pest Control for a FREE estimate, professional service, and THE best solution to your termite control needs.
