Termite Season

Termite Season

What Time of Year Do Termites Appear and for How Long?

Many people think prime termite season is when termites appear in swarms. However, termites that have infested a house can cause damage at any time, regardless of the weather or presence of warning signs like swarms.

Spring is the swarming season for most subterranean termites.

Most species of subterranean termites swarm during the spring and summer months, typically on a warm day with calm winds after a rainfall.

Drywood termites and one particular species of subterranean termite (R. hageni) typically swarm during the late summer or fall months, from August through November.

There are several subterranean termite species and they don’t all swarm at the same time. (On the other hand, dampwood and drywood termites typically swarm in the summer.) Species generally swarm based on favorable weather conditions. Varying conditions may mean that swarms will occur at different times. For example, some species prefer more moisture than others. Separation in swarm timing may be a matter of a few weeks, or time of day.

Springtime Flowers and Termite Swarms

Swarms can be loosely linked to the blooming of certain trees. For example, one of the Eastern subterranean species typically swarms when the dogwood tree buds swell and the flowers first appear. The swarming of a closely related species was once linked to the blooming of chestnut trees, but a blight killed most of those trees, so we have to find another marker.

Since most species of subterranean termites swarm in the spring and summer (and subterranean termite swarms are much bigger than drywood swarms), this time frame is when homeowners are more likely to notice signs of an infestation.

During summer, the activity inside a subterranean termite colony begins to settle down to the events of foraging and eating. Past is most of the frantic activity associated with releasing the swarmers – selecting the right days (after a rain, limited wind and optimal humidity), the best time of day, how many to “launch” at a time, and how many launches will be needed to get them all out.

Summer Activity

Finished are the days (and nights) of soaking springtime rain. This moisture created all sorts of problems inside the colony, especially if parts of the colony were flooded. Seasonal conditions resulted in the death of many workers, and now the workforce is smaller. But the secondary queens kick in with plenty of egg production and the number of workers increases. The weather is also more predictable. The upper layer of soil is warm and moist, and there is plenty of food to be found.

Fall Swarmers

Flight times for species vary based on favorable weather conditions, which means that not all termite reproductives swarm at the same time.

In the eastern United States, the major species typically swarm about a month apart, with Eastern subterranean termites (Reticulitermes falvipes) going first in April, followed by dark Southern subterranean termites (R. virginicus) in May.

There is one termite species, light Southern subterranean termites (R. hageni), which prefers quite different weather conditions, opting to swarm in the fall. Swarms of this species may extend from August (cities along the eastern seaboard) to November (in the Deep South). The winged adults in this species are slightly smaller and pale brown, and often swarm during the same time of day as the spring swarmers (late morning). This species’ size and color often gets it confused with ants that swarm at the same time of year.



What are the most common signs of termites?

Because so much of the damage caused by termites is within the inner walls of a structure, it can be difficult to know if you have a termite problem. However, there are three warning signs to help you determine if you have a termite problem.


Winged termites are often the first sign of a subterranean termite infestation. Swarming termites are attracted to light and are often found near windows, doors, vents and light fixtures. Experiencing a termite swarm is the #1 sign that your property has a termite problem. Worker termites are small, light-colored insects that move quickly when exposed to light. They are also the family members that cause the most damage to a structure. Even if you haven’t seen signs of termites, check windows, heating vents, doors, sinks and bathtubs for dead termites or termite wings.

Mud tubes provide shelter for termites and have a muddy, flattened appearance approximately the width of a drinking straw. Look for mud tubes along cracks, beneath flooring, around baseboards, on pipes, piers, chimneys, behind siding, plumbing and other fixtures. Mud tubes may also extend over concrete foundations and other exposed surfaces.

Another way to check for termites is to tap wood along the walls, baseboards and windowsills every few inches with a screwdriver handle. Damaged wood will sound hollow and, if the area is extremely damaged, the handle may break the wood’s surface. If the area is active, you may see worker termites inside. Dark areas or blisters in wood flooring are an indicator of a subterranean termite infestation. Because subterranean termites are preventable, it is a good idea to have your property regularly inspected by a trained specialist.

How much damage can termites really do?

Termites cause an estimated $5 billion in property damages and repair costs annually. In fact, termites damage more homes than fires, floods and tornadoes. More than 4 million homes in the United States are at risk of infestation this year.

How do I know if I have winged ants or swarming termites?

Winged termites have pigmented bodies with broad waists and two pair of wings that are equal in size and shape. Subterranean termite swarmers have bodies about one-quarter of an inch in length. The swarmers quickly shed their wings after a brief flight. Winged ants have pinched waists and two pair of wings that differ in size and shape (front pair is much larger). Flying ants shed their wings like termites. Termite wings are all the same size. Collect a few and call Terminix to have them identified if you want to be sure.

Termite workers are pale, soft-bodied insects about one-quarter of an inch or less in length. They appear to have a head and body because their thorax is broadly joined to their abdomen. Their antennae are straight.

Termites are mistakenly called white ants, but are not ant-like in appearance. Ants are usually heavily pigmented and have three distinct body regions: head, thorax and abdomen. Ants also have a very narrow or pinched “waist,” and their antennae are “elbowed.”

Winged termites, also known as swarmers, have pigmented bodies with broad waists and two pair of wings that are equal in size and shape. Subterranean termite swarmers have bodies about one-quarter of an inch in length. The swarmers quickly shed their wings after a brief flight. Winged ants, on the other hand, have pinched waists and two pair of wings that differ in size and shape (front are much larger).

How can I tell if pest excrement is from termites or other insects?

Drywood termites produce small bun-shaped excrement. This often accumulates on surfaces directly below infested areas. Evidence of activity can include small “pin holes” in the surface of the infested area and the droppings accumulating below. Swarmers might also be observed. The adult reproductives swarm to start new infestations in other areas of the structure. This usually occurs between early summer and late fall depending on where you live.

There is mud tunnel on the drywall of my exterior wall. Should I be worried about termites?

Mud tunnels are one of the top indicators of subterranean termite activity. Contact your local Terminix branch as soon as possible.

Do termites really eat wood?

Yes, termites really eat wood. In nature, termites play a useful role helping wood be recycled to the soil as humus, an organic material that provides nutrients for plants and increases the ability of soil to retain water.

Using bacteria, protozoa and microbes that live inside their stomachs, termites are able to digest cellulose, the main constituent of wood. They are extremely well organized and persistent in their search for new food sources. Contrary to what one might think, they will eat anything containing cellulose – wallpaper, books, boxes, carpet backing, drywall and even furniture.

Can termites make their way through concrete?

Termites cannot go through solid concrete, but they can get through a crack only 1/32 nd of an inch wide. Openings this size or bigger often occur where two pieces of concrete abut – like when poured separately – and around plumbing penetrations through the concrete or where the concrete has cracked.

How long do termites live?

A worker termite may live from one to two years. A queen termite may live for decades.

Why do winged termites lose their wings?

Swarmers use their wings to fly a short distance from their nest. They then break off their wings and never fly again, burrowing themselves in the soil to spend the remainder of their lives building a new colony.

What will termites do after they swarm?

Subterranean termite swarmers attempt to pair with a swarmer of the opposite sex within their colony. They must locate a suitable habitat to establish a new colony of their own. They need moist soil, preferably in direct contact with wood, in order to survive. The termites that swarm inside a structure and cannot get out will quickly die from lack of available moisture. The termite colony that produced the swarmers will continue to be active after the swarm has taken place.

How do termites get ins >

Termites don’t need much room to squeeze inside your home or business. In fact, they can enter a structure through a space as small as 1/32 nd of an inch.

Subterranean termites usually enter a building from the soil along its foundation or through cracks in the slab, expansion joints, weep holes, voids in brick or block and around plumbing. Decks, porches and other wood structures in direct contact with the ground are also easy access ramps for termites.

While most subterranean termite infestations can be traced to a colony living in soil outside the structure, some infestations begin above the ground. This occurs when a termite king and queen begin a new nest within a structure or when foraging termite workers become isolated and cannot return to the parent colony. Such conditions are most common in high-moisture areas. Structures with flat roofs or chronic leaks can also be at risk because the structure can retain enough moisture for a termite colony to establish itself. Constant moisture allows a termite colony to survive even without a connection to the soil. In such cases, the structural moisture problems may be as damaging to the home as the termite activity.

Common construction practices can also contribute to termite problems by providing termites admittance into a structure or creating ideal damp conditions for colonization. Some examples of these practices include wood-to-soil contact, form boards not being removed after construction is completed, wood refuse buried under the slab, improper drainage and stucco below grade.

Spreading mulch over the soil adjacent to a structure’s foundation can also provide an inroad for termites to creep into a building.

Does the builder of a new home usually protect it against termites?

There are only a few states that require soil pretreatment for control of subterranean termites during construction. It is usually the mortgage lender that requires this, especially in termite-prone areas.

I have an old tree stump infested with termites. Should I have it treated?

You don’t need to treat the stump, but you may want to give your home termite protection. In areas of the country where termites are common, it is not unusual to find them in the ground, in tree stumps or in debris near a structure. If your home has not been treated to control or prevent termite entry, you should maintain a close watch for termites and have a Terminix specialist inspect and implement a termite control program.

Subterranean termites nest in the ground and forage for food (cellulose or wood) over areas up to one-half of an acre or more in size. There is a high probability that if they are detected close to your home, they will eventually infest it – if they have not done so already. Treating the stump will not have any great impact on the colony or its continued search for new food sources. Contact your local Terminix branch for an inspection and to find out your control options.

Preventative action makes good sense in any termite-prone area, and you should also consider having Terminix implement a termite control program before you notice an infestation.

Remove all wood debris from around your home, especially after new construction and remodeling. This includes wood form boards along foundations, tree stumps and roots, as well as firewood stacked near the house.

Since termites need moisture to survive, grade the soil around your foundation so it carries water away from the house. Keep gutters and downspouts in good repair.

Will subterranean termite swarmers infest my house, furniture, closets, etc.?

Subterranean termite swarmers are looking for moist soil in close proximity to wood in order to start a new colony. The likelihood of these conditions existing inside your home is very low, so unless the swarmers get outdoors, they will not survive.

There are homes with termites in my neighborhood. How can I protect my house?

Termites forage year-round and they spread most commonly underground. If your home is currently termite-free, it could become infested by termites that are active nearby. A preventative termite control program will help avoid termite infestation. Contact your local Terminix branch for additional information about termite biology, habits and treatment options.

I live in a stucco home. Should I be concerned with termites?

Termite problems are common in stucco homes. Usually this is because the stucco exterior finish extends beneath the soil level around the outside of the structure. This creates a small space between the foundation and the stucco finish, permitting termite entry that is completely hidden from view.

Another situation involves the “synthetic” stucco finishes that have a base layer of rigid foam board. This type also often extends beneath the soil level, and once the termites access the foam, they can move anywhere around the structure. This type of exterior finish is also prone to moisture intrusion, which will help support the termites once they get in.

How do I get r >

More than likely, a home infested with drywood termites will require tent fumigation. Tent fumigation involves covering your home with tarps and introducing a fumigant gas to penetrate all infested wood. It is the most effective method of controlling drywood termite infestations.

How can I prevent a termite infestation?

Terminix will get to subterranean termites before they get to you. The Bait Barrier Plan establishes an advanced treatment perimeter around your home and provides annual monitoring to check for termite activity. A second option, the Subterranean Termite Coverage Plan, offers an annual professional Termite Inspection and free treatments if termites are discovered. Both plans are backed by an ongoing guarantee protecting against any costs from future treatments or damage repairs.

My house does not have termites – should I still get a termite treatment?

Yes. Without an effective prevention program, like our Bait Barrier Plan, your home is open to termite damage, which could remain unnoticed until it becomes a serious problem.

The Terminix Bait Barrier Plan is designed to eliminate termites and their colonies.

Keep in mind that just because you don’t see termites does not mean your property is safe from infestation. Subterranean termites live in colonies that can house hundreds of thousands of termites. They work 24 hours a day and are often difficult to detect since 80 percent of the wood they eat is hidden within the structure.

How long does it take to eliminate or control a termite colony with bait?

Individual termites can be affected within a few days after consuming the bait, but it may take several months before an entire colony is controlled or eliminated. This varies depending on the time of year, geography, the number of termites in the colony, the number of colonies infesting the structure and the species of termite.

How do I control termites and avo >

There are many effective options based on the type of termites found at your home. Terminix recommends a Termite Inspection in order to determine the best method and treatment plan. Liquid treatments use applications to the soil at potential entry points into the structure. As the termites forage for food sources, they come into contact with the treatment area if they try to enter the structure.

Soil treatments are intended to control termites for extended periods of time, although they may be breached because of physical disturbance of the treatment zone (landscaping activities, construction, erosion), tree roots growing through the treatment zone and natural degradation of the termiticide, among others. For these reasons, most termite control treatments are available with renewable guarantees.


When Do Termites Swarm?

Imagine this. You wake up on a beautiful warm morning, walk to the kitchen and discover that there are hundreds of winged insects twitching about the doorway and the floor. These insects do not seem to fly well and most of them are dead or dying. This is not the scene of the latest B-thriller. This is the aftermath of a termite swarm or an ant swarm. Flying termites have snuck into your home and now you have to deal with them.

The absolute worst thing you can do right now is sweep the bugs outside and ignore them. It’s time to check out what the swarmers look like and then contact an exterminator. Getting a termite inspection for your home and property now can save a lot of heartache (and cash) later. Although termite swarms happen only in warm or hot weather, termite colonies can live year-round.

The Importance of Witnessing Swarms

Termites spend lives mostly hidden away from humans. They can live underground or inside wooden structures, including your home. By the time you actually see termites falling out of the walls, severe damage has been done to your home. The only time termites are clearly visible is during the spectacular breeding swarms. Seeing a termite swarmer near your home could be your only clue that termites live near or even worse. in your home.

The termites or ants in these swarms only come out when the weather is warm or hot. If you live in a warm climate year-round, then you need to be on the lookout for these swarms year-round. These insects come out of their colonies in order to breed and then start off new termite colonies. If you discover a swarm in a part of your home that is well-heated throughout the winter, then it is possible for termite breeders to assume that it’s spring or summer and swarm. Cold quickly kills these breeders but does not kill the rest of the colony.

If You See A Swarm in Your Yard

Perhaps a breeding termite swarm is seen covering a tree, shrub, fence or outbuilding in your yard. Does this mean that the termite colony is far enough away from your home so that you do not have to worry? No. In fact, it’s time to start worrying. ​Subterranean Termites tunnel underground from incredibly long distances away from their colonies.

Termite scouts are blind, but they are able to follow the scent of cellulose and other food like paper, wood and even gardening mulch in the soil. If a scout finds food, it takes a piece back home to the colony. Scouts lay down a scent trail easy for other workers to follow back to the food source.

Differences of Ant Swarmers and Termite Swarmers

Both ants and termites breed in swarms of winged males and females. Both can be about the same size – up to an inch long- and both can have dark-colored bodies. However, there are some major differences between termite breeders (also called alates) and ant alates. Since most of the swarmers will die soon after mating, you should be able to find dead insects to study.

Check out the critter’s wings, antenna and body:

Wings: Both ants and termites have two pairs of wings, but both pairs of termite wings will be the same size. Ant wings will be different sized.

Antennae: Ant antennae will be bent while termite antennae will be straight.
Body shape: (This may be difficult to determine if a bug is curled up.) Ants, close relatives to bees and wasps, have a very skinny waist while termites have no waist at all. Their bodies are shaped like torpedoes.
If you are still not sure if the swarm is an ant swarm or a termite swarm, save a corpse or two in a plastic baggie or other container and show it to an exterminator.

What if You Find A Pile of Wings?

Ant and termite alates only keep their wings as long as they need them. They tend to shed them after their mating flights or even bite them off. Wings are of no use to creatures that now are going to spend the rest of their lives underground or embedded in food sources. In this case, you may not see insect bodies but come across small piles of discarded insect wings.

It’s difficult to determine the difference between ant wings and termite wings just with the naked eye – or even if you’re armed with a magnifying glass. These wings are incredibly fragile and fall apart under even the most gentle of handling. The best thing you can do is contact an exterminator and schedule a termite inspection.

What if You Find Streaks of Mud Near Swarms or Wings?

Perhaps you witness a swarm coming out from what look like stripes or streaks of dirt around your window frames, doorways, porch steps or anywhere else in your home. Those dirty stripes are called mud tubes. They were made by termite workers. Termite bodies, except for breeders and queens, quickly dry out and die when exposed to heat and light. Termites do not have hard shells to keep in moisture.

In order to keep their bodies cool and moist, workers build tunnels made with dirt and termite spittle. Winged breeders crawl through these tunnels and then burst out when it’s time for termite love. Workers will repair these tunnels if they lead to more food. Ants do not make mud tunnels. Their hard exoskeletons are excellent for keeping in moisture.

Typical Time Period of Termite Swarmers

When do termite swarms happen? During warm weather or inside rooms kept toasty warm.

Remember, termite swarmers have two pairs of same-sized wings and straight antennae. Seeing a swarm is sometimes the only clue you as a homeowner might have that termites are fixing to feast on your home. Termite swarms are a big neon sign that you need to contact a professional exterminator.
