Seeing Winged Carpenter Ants? Here’s What It Means for Your Home

6 minutes

Well hello there, homeowners. Will White here from Nexus Pest Solutions. If you’re like

many folks I talk to around Mequon and Milwaukee, you might have recently spoed

some ants that look a lile…dierent. Specically, you might be seeing carpenter ants

with wings, and naturally, you’re wondering what’s going on. Let’s break it down,

because seeing these winged ants is an important sign, and understanding their life

cycle is key to protecting your home.

Why Am I Seeing Carpenter Ants with Wings?

Think of these winged carpenter ants as the future of the colony. They aren’t just

regular worker ants who suddenly grew wings. These are what we call “swarmers,” or

the reproductive members of a mature carpenter ant colony. Their appearance is part

of a natural process called a “nuptial ight.”

Essentially, when a carpenter ant colony gets to a certain size and maturity – typically

aer a few years – it’s ready to expand and create new colonies. On a warm, oen

humid day, usually in the spring or early summer here in Wisconsin, these winged male

and female swarmers emerge from the existing nest in large numbers. Their mission is

singular: to nd a mate and start a new colony.

Seeing these swarmers inside your home is a prey strong indicator that you likely

have an established carpenter ant colony living within the structure of your house. If

they were coming from outside, you’d typically see them trying to get in, usually

around windows or doors. Finding them already inside, sometimes disoriented or with

discarded wings nearby, signals that the colony is likely nestled in your walls, aic,

crawl space, or other wooden elements of your home.

It’s important not to panic, but it is a sign that warrants investigation. Unlike termites,

which actually eat the wood, carpenter ants tunnel through wood to create galleries

and nests. Over time, this can weaken the wood and cause structural damage. The

presence of swarmers means the colony is mature enough to reproduce, which also

means it’s been there for a while and has a signicant number of ants.

How Long Does It Take for Carpenter Ants to Develop Wings?

This is a great question, and it helps us understand the timeline of a carpenter ant

infestation. A carpenter ant colony doesn’t just pop up overnight and immediately

start producing winged swarmers. It takes time for a colony to grow and mature to the

point where it’s ready to reproduce.

From the time a single fertilized queen starts a new colony, it can take anywhere from

three to six years for that colony to become established and large enough to

produce the winged reproductive ants you’re seeing. During these initial years, the

queen focuses on laying eggs that develop into the wingless worker ants. These

workers are responsible for foraging for food, excavating the nest galleries, and caring

for the young.

Once the colony reaches a certain population size and maturity, typically housing

several thousand workers, the queen will then begin to lay eggs that will develop into

the winged males and females – the swarmers. These swarmers will stay within the

nest over the winter and emerge the following spring or early summer when

conditions are right for their mating ight.

So, if you’re seeing winged carpenter ants indoors, it’s a clear indication that you’ve

had a carpenter ant presence for at least a few years, possibly longer. This

underscores the importance of addressing the issue promptly to prevent further

damage to your home’s structure.

How Long Does the Queen Carpenter Ant Live?

Now, let’s talk about the queen, the matriarch of the entire operation. She’s the

reason the colony exists in the rst place, and her lifespan is quite impressive for an

insect.

Once a female swarmer successfully mates during the nuptial ight, she becomes a

queen. She then nds a suitable location to start her new colony – oen in a piece of

moist or damaged wood – sheds her wings, and begins laying eggs.

A single carpenter ant queen can live for an astonishingly long time, potentially up to

25 years, or even longer in some cases. Throughout her lifespan, she is the primary

egg-layer for the colony, responsible for producing all the workers and, eventually, the

next generation of winged swarmers.

Her longevity is a key factor in the persistence and potential growth of a carpenter ant

problem. A healthy, long-lived queen can produce tens of thousands of ospring over

her lifetime, leading to a large and well-established colony that can cause signicant

damage if le unchecked. This is why simply dealing with the visible winged ants or a

few foraging workers isn’t enough to eliminate the infestation. You need to locate and

eliminate the main nest, which houses the queen.

Puing It All Together

Seeing winged carpenter ants is a sign that a mature colony is present, likely within

your home’s structure. This colony has been developing for several years, thanks to a

queen that can live for a very long time, continuously producing more ants.

My goal at Nexus Pest Solutions is to help you understand these pests and, more

importantly, to help you live pest-free. If you’re seeing winged carpenter ants, or any

other signs of carpenter ant activity like sawdust-like material (frass) or quiet rustling

sounds in your walls, it’s time to take action. We can help identify the extent of the

infestation, locate the nests (both parent and satellite nests), and develop a targeted

plan to eliminate them and protect your home from further damage. Don’t let these

winged invaders signal the start of bigger problems. Give us a call, and let’s get your

home protected.
