May is prime time for termite swarmers Kansas City homeowners often see across the metro area. If you are seeing clouds of small dark winged insects near your foundation, your trees, or even inside near a window, this blog is for you.

What is a termite swarm?

When a termite colony matures, it sends out winged reproductive termites called swarmers. Their job is simple. Fly out, pair up, find a new spot to start a colony, and shed their wings.

Swarms usually happen on warm days after a rain, often midday. They can last just a few minutes or up to an hour.


Termite Swarmers Kansas City Guide: Termites vs. Flying Ants

This is the most common mix-up we see. Here is how to tell them apart.

Termite swarmers:

  • Straight antennae

  • Two pairs of equal-sized wings

  • Thick waist (no pinch)

  • Wings often shed in piles


Flying ants:

  • Bent or elbowed antennae

  • Front wings larger than back wings

  • Pinched waist

  • Wings stay attached longer


If you find piles of small wings on a window sill or near a sliding door, that is a strong sign of termite activity.


Why this Termite swarmers matters in Overland Park

Eastern subterranean termites are the main termite found in Kansas and Missouri. They live underground and travel up through mud tubes to feed on wood. They do not stop because winter is over. They have been working all spring.


KC metro homes with mature trees, wood mulch, and irrigation are particularly attractive to termites. By the time you see swarmers, the colony has likely been there a while.





What you should do

If you see swarmers outside, mark the spot. Look for mud tubes on the foundation or piers under your home.


If you see swarmers inside, give us a call. Do not spray them with household bug spray and walk away. We will come take a look and let you know what we find.


A wood-destroying insect inspection is also smart if you are buying or selling a home.

A Swarm Means the Colony Is Already Established

Here is the part most people do not know. A swarm is not the start of your termite problem. It is a sign of one that already exists.

Colonies do not produce swarmers until they are mature, which usually takes years. So when you see a swarm, the colony behind it has been in or near your property for a while.

That is not a reason to panic. It is a reason to look.

Why Johnson County Raises the Stakes

Two things about Johnson County housing matter here.

Finished basements. A huge share of homes in Overland Park, Leawood, and Prairie Village have them. Finished walls cover the exact spots where a mud tube would be visible, so the early warning signs stay hidden behind drywall. Many homeowners find out only when paint bubbles or a baseboard sounds hollow.

Mature tree cover. The established neighborhoods off Metcalf and Nall have deep shade, soil that never fully dries out, and decades of root and stump material underground.

Newer construction in Olathe and Lenexa has its own weak point. Grading and fill dirt around a fresh slab give termites an easy route along the foundation.

Honest Talk About Termite Sales

Termites are the pest where fear sells hardest. You have probably seen the pitch. Photos of collapsed floors, urgency, sign today.

That is not how we work.

Swarmers in your yard in April are normal. Old mud tubes with nothing living in them are not an emergency. If that is what you have, we will say so and we will not invent a reason to sell you a treatment.

When there is real activity, we will tell you that straight too, and we will explain what we found and why it matters before we talk about anything else.

No contracts. Not now, not ever. Every termite treatment carries a one year warranty. If termites come back inside that window, so do we.

How Our Termite Service Works

You do not need an appointment just to talk about termite control.

Text us a photo at (913) 222-2847. We identify it. We then use property measuring technology to pull your home's dimensions remotely, which gives you a real estimate without a sales visit. If you want to move forward, we get you on the schedule.

The one visit you book is the one where the work happens. Your technician inspects the structure and treats it on the same trip.

We handle wood destroying insect inspections for real estate closings too, which most lenders require.

Frequently Asked Questions

When do termites swarm in Kansas City?

Spring, usually March through May, once daytime temperatures reach about 70 degrees. Swarms often happen on a warm day right after rain, typically around midday.

Are termites common in Overland Park and Johnson County?

Yes. Eastern subterranean termites are native to the area. The metro's rainfall and the number of homes with finished basements, where early signs stay hidden, make it consistently active.

Does seeing termite swarmers mean I have termites in my house?

Not necessarily. Swarmers outdoors are common in spring and may come from a colony in a neighbor's yard, a stump, or a woodpile. Swarmers indoors are different. Those almost always mean a colony is already in or under the structure.

How can I tell termite swarmers from flying ants?

Three things. Termites have straight antennae, a thick waist with no pinch, and two pairs of wings the same size. Flying ants have elbowed antennae, a pinched waist, and front wings larger than the back pair.

How long does a termite swarm last?

Anywhere from a few minutes to about an hour. Once it is over, the wings left behind are often the only evidence.

Should I spray termite swarmers myself?

No. Store bought spray kills the visible insects and does nothing to the colony, and it can push activity deeper into the structure where it is harder to locate.

Can you identify termites from a photo?

Most of the time, yes. Text a clear, close up photo to (913) 222-2847 and we will tell you what you are looking at. There is no charge.

Do I need an inspection appointment before you can give me a price?

No. We can identify the pest from your photo and use property measuring technology to price your home remotely. There is no separate sales visit.
