Do you notice small winged insects emerging near your windows or doors on warm evenings? These are termite swarmers, and their appearance is a strong sign that a mature colony may be active near your home.
While the swarmers themselves don’t cause direct damage, they indicate that termites are reproducing and expanding, putting your property at risk. Early identification is key to preventing costly structural damage.
By spotting discarded wings, mud tubes, or other signs of activity, homeowners can take immediate action to protect their home’s safety and value before infestations worsen.
What Are Termite Swarmers?
Termite swarmers, also called alates, are winged termites that leave their colony to mate and establish new colonies. Unlike worker termites, which remain hidden, swarmers are visible and often mistaken for ants because of their wings and similar size.
Unlike flying ants, termite swarmers do not have a pinched waist, and have two pairs of wings that are equal-sized. And double the size of the body. So if the body is half the size of the wings - you have termites.
Termite swarmers are usually dark brown or black and found in clusters within the same area of the home. size. Subterranean termite swarmers have a black head and black body, and most commonly seen during early spring after spring rains.Moisture creates ideal conditions for subterranean termites, and triggers the queen to create flying termites for expansion purposes.
Black termite swarmers are from subterranean termites. Black termite swarmers with an orange/red head are from drywood termites.
Drywood termite swarmers are seen during late summer & early fall. When the drop of temperature from the hot suns of summer to the milder climate of fall triggers the queen to create flying termites.
The appearance of termite swarmers in or around your home is a warning sign that a colony is present nearby or even inside your property.

How to Differentiate Termite Swarmers from Flying Ants
Flying ants and termite swarmers appear in the same season and can be easily confused. However, several characteristics set termite swarmers apart:
- Wings: Termite swarmers have two pairs of wings that are equal in length and twice as long as their body, unlike ants, whose front wings are longer than the back. Ant wings are also different sizes.
- Antennae: Termite antennae are straight and beaded, while ants’ antennae are elbowed.
- Body Shape: Termite swarmers have a broad and wide waist, whereas ants have a narrow, pinched waist.
Recognizing these differences helps ensure proper identification.

Common Termite Swarmers in Southern California and Their Swarming Seasons
Several termite species are active in Southern California, each with distinct swarming behaviors and seasonal patterns tied to environmental conditions like temperature, humidity, and rainfall.
- Subterranean Termite Swarmers: The most common and destructive in the region, subterranean termites live in large underground colonies and require soil moisture to survive. Their swarming typically occurs in spring, often after rainfall on warm days. These swarmers indicate a colony capable of causing extensive damage to structural wood, flooring, and furniture if left unchecked. Because they come from the ground up, they cause damage for years before leaving any signs that they’re there.
- Drywood Termite Swarmers: Unlike subterranean termites, drywood termites do not need soil contact and establish colonies directly within wood structures, attics, or furniture. Termite swarmers fly in, and each swarmer can become its own queen and colony. Their swarming season peaks from late summer to early fall, usually between September and November. While slower in pace, drywood termites can silently compromise wooden structures over time.
Awareness of these seasonal patterns allows homeowners to remain vigilant during termite swarming season and take timely action to protect their property.
Spot early signs of termite activity and protect your home - learn how to detect infestations before damage spreads.
Signs of Termite Swarmers in Your Home
Spotting termite swarmers can be alarming, but early detection is essential. Key signs to watch for include:
- Flying insects around lights, windows, and doors
- Piles of discarded wings on windowsills, floors, or counters
- Tiny pellet-like droppings (frass) from drywood termites
- Mud tubes along baseboards, foundations, or exterior walls (subterranean termites)
- Hollow-sounding wood or visible blistering, splintering, or damage
Noticing any of these signs should prompt immediate inspection and intervention.
Note: Termite swarmers can indicate a hidden colony that may be damaging your home’s wood structures and foundation. K Termite offers FREE termite inspections to detect any signs of activity and provides multiple treatment options to effectively address infestations.

How Termite Swarmers Affect Your Property
While swarmers themselves do not directly eat wood or structures, they are essential in colony reproduction and expansion. Their emergence often signals that a colony has reached maturity and that workers are actively feeding on structural timber. The presence of swarmers near or inside your home can lead to:
- Structural Damage: Termites feed on cellulose found in wood, cardboard, and other materials. Over time, they compromise the strength of beams, floors, and furniture.
- Hidden Infestations: Termite activity often occurs behind walls, under floors, and in ceilings, making early detection critical to preventing extensive damage.
- Costly Repairs: Untreated termite infestations can result in thousands of dollars in repair costs, including wood replacement and structural reinforcement.
- Increased Risk of Spread: Swarmers can establish new colonies near your property, leading to recurring infestations if not addressed promptly.
Recognizing swarmers and acting quickly can significantly reduce these risks. Homeowners who regularly inspect their property and respond to early warning signs are more likely to prevent major damage.
Don’t let termites eat your savings - see how prevention costs less than dealing with expensive repair bills.
Immediate Steps to Take if You Spot Termite Swarmers in House
- Do not clean up all evidence. Dead swarmers or wings help professionals identify the species.
- Collect samples. Place several dead swarmers or wings in a labeled container for inspection.
- Document activity. Take photos of swarmers, damage, or mud tubes to share with a professional.
- Contact a termite specialist immediately. Early professional assessment prevents further structural damage.
Termite swarmers may seem like a minor nuisance, but their presence is a clear warning of an active colony nearby. Left unchecked, termite activity can cause severe structural damage, lower property value, and create hidden problems within your home.
By staying vigilant, conducting regular inspections, and working with professionals like K Termite, you can identify termite activity early and protect your property from costly repairs. Acting quickly when termite swarmers are noticed ensures that your home remains safe, strong, and structurally sound for years to come.
Your home deserves protection from hidden threats. Let K Termite help you maintain the safety and value of your property with expert inspections, effective treatments, and reliable support every step of the way.
Frequently Asked Questions
Q.1 What do termite swarmers look like?
Termite swarmers are winged adult termites, usually dark brown or black, with two pairs of wings that are equal in length. They have straight, beaded antennae and a broad waist, which differentiates them from flying ants. They are often seen near windows, doors, or light sources during swarming events.
Q.2 Do termites come out at night?
Some termite species, like Formosan termites, often swarm in the evening, especially during warm, humid conditions. Other species, such as subterranean and drywood termites, are more active during the day, particularly after rainfall or when conditions are favorable for flight.
Q.3 How to get rid of termite swarmers?
The most effective way to address termite swarmers is by treating the colony itself. This includes professional inspections, targeted treatments, and, if needed, structural repairs. Collecting samples of swarmers or wings can help professionals identify the species and choose the right treatment plan.
Q.4 Are termite swarmers dangerous?
Termite swarmers are not harmful to people or pets. The danger comes from the colony they represent, which can silently damage wood structures, flooring, and foundations if left untreated. Early detection and professional intervention are key to preventing significant damage.
