Well, in our complete guide to Termite Swarming: Everything You Need to Know About Swarming Season, you’ll find the answers to all your termite questions.

Let’s begin!

Why Termites Swarm?

Swarming allows termites to reproduce and establish new colonies near food sources. Termites are highly gregarious insects that thrive in groups. In the spring, young termites acquire wings to swarm away from their parent colonies.

The breeze frequently pushes along the swarms until they reach the ground, even though they don’t fly for very long. These bugs can start new colonies once they touch down again.

Termite Colonies typically swarm once a year, though several swarms may occur in rare situations. Multiple swarms occur in a season, but they are usually smaller than the first.

When is termite season?

Termites are active year-round, but they swarm more frequently during certain times of the year.

Generally, it is during the warmer months, usually from March to October, when termite colonies frequently swarm to find a mate and start a new colony.

However, as mentioned above, termites remain consistently active year-round in warmer climates while they become less active during winter months (November-February) in colder regions.

Therefore, if you’re seeing a lot of termites around your home, it’s likely that you’re in the middle of the swarming season.

Types of termites

subterranean termites

Though there are many different kinds of termites around the world, they may all be divided into three groups: subterranean termites and drywood termites.

And even though varieties have many similarities, they also have numerous variances in terms of behavior, dwelling habits, and swarming patterns.

Drywood termites

Drywood termites swarm in order to propagate their species. They swarm in the late winter or early spring when the weather is warm and humid. You may see large numbers of termites flying around your home or property.

Drywood termites are attracted to light and will often enter homes through windows and doorways.

These termites cause extensive damage to wood structures, as they consume the wood from the inside out. In order to protect your home from these pests, it is important to be able to identify them and understand their behavior during swarm season.

Subterranean termite swarmers

Subterranean termites swarm in the late winter or early spring. They are darker in color than drywood termites, with a longer body, wider head, and wings that are a pale-to-clear color.

The swarmers are commonly seen during the day. These critters live in mud tubes created by the soldiers of the swarms. The soldiers protect the colony from invaders and build the mud tubes.

Another fascinating aspect is how their dietary habits differ. These pests are more particular about the wood they use. Because they live in mud tubes, they are frequently discovered around the house’s foundation.

The mud tubes are frequently visible while they eat. They do, however, eat against the grain of the wood. The softwood in between the grains appeals to them. This is very different from drywood termites.

They must be kept away from your home because they might cause damage if they come inside.

Black House Termites

Blackhouse termites are a subterranean species of termite that can be difficult to distinguish from carpenter ants. They are most commonly found in the Southern United States and build their nests underground.

In addition, black wingless termites are not as uncommon as one would think and should be monitored closely. They can cause significant damage to structures if they are left untreated.

How to Identify a Termite Swarm?


Termite infestations can happen in the blink of an eye; therefore, recognizing termite swarms quickly and correctly is critical. 

The swarming stage occurs when many termites are ready to form a new colony and reproduce to populate it.

Termite swarmers resemble flying ants in many ways, and they don’t arrive alone! Termite colonies start immediately after swarmers land in a favorable location.

Termites may live almost anywhere with a cellulose source and a moderate moisture level—exactly the kind of habitat your home provides!

Here’s how to determine the difference between flying ants and termite swarmers: 

  • Antennae: Termites have straight antennae, but ants have curved antennae. 
  • Wing structure: Termite wings are of the same length, whereas ant wings vary in length.

Another way to tell whether you have a termite swarm is to look for abandoned wings surrounding the entry point, commonly a door or window sill. 

The wings of swarming termites are only temporary and fall off quickly after landing. If you notice abandoned wings near the swarm, it’s likely not flying ants! 

So What Does This Mean for My Home?

 If you’ve discovered a termite infestation on your property, it is advised to act immediately. Termite swarmers begin establishing a new colony as soon as they arrive in a suitable area, and infestations can develop quickly.

However, the first step is to determine which termite species you have in your home before proceeding. One of the simplest methods is to assess the extent of the termite damage to your home.

  • Drywood termites cause significant harm to the wood they infest. Examine your roof or attic for signs of termites tunneling into the wood, such as small holes in wooden surfaces, to check for this termite species. Infestation and eventual damage are more likely on wood surfaces that are directly exposed to the elements.
  • Subterranean termites dwell underground, and their destruction begins from that site itself. If your property has a subterranean termite infestation, the first area to look for damage is the parts closest to the ground, particularly the crawlspaces. Damaged wood structures in your crawl area, as well as obvious mud tubes running along walls and other nearby structures.

What Should I Do If I Discover Termite Signs?

If you have discovered termite signs, it is important to take action as soon as possible; particularly because the longer you wait, the more harm termites will be able to cause.

First, inspect for signs of the pests. It would help if you looked for mud tubes, discarded wings, and wood damage. Once you have determined where the termites live, it is easier to determine their entry point and take steps to address the problem.

Secondly, keep an eye on the affected area and take pictures or videos as evidence. You can then reach out to a local pest control company for assistance.

It is highly advised not to panic when you discover signs of a termite infestation. Remember, You can do a few things to mitigate the damage and get help from professionals.
