Right now / the room they came from

Termite Swarmers in the House: Do This Now

An indoor swarm usually ends within the hour, and it points at a colony in or under your home. Here is what to do before the evidence disappears.

Next sixty minutes

Do not spray. Bag a few. Photograph before you clean. Write down where and when.

What is happening in that room has a shelf life of about an hour, and the evidence is worth more than the tidying.

They came out of a floor register, a crack beside the fireplace, or the trim around a window. Dozens of small dark insects with milky wings, all at once, all crawling and fluttering toward the light. If that is what you are looking at, close this tab after the checklist below, because what is happening in that room has a shelf life of about an hour.

One caveat before the list: if you have not confirmed they are termites, the 10 second antennae, wings, and waist check settles it. Straight antennae, four equal wings, no pinched waist means termite. Then work the steps in order.

In order

Do this in the next hour

The insects in the room were never the problem. The source is.

  1. 01 It kills messengers, not the source

    Do not spray anything

    A can of spray kills the messengers and leaves the colony untouched. Worse, it scatters the evidence an inspector uses to trace where they emerged. The insects in the room were never the problem; the source is.

  2. 02 A real sample beats a blurry photo

    Bag a few insects

    Press clear tape over several swarmers or shed wings, or scoop a few into a zip-top bag. Species identification from a real sample beats a blurry photo every time.

  3. 03 Coverage matters more than lighting

    Photograph before you clean

    One wide shot of the room, one close up of the insects, one of the exact spot they came out of. Lighting does not need to be good. Coverage does.

  4. 04 Emergence points map the route

    Write down the where and when

    Which room, which wall or register, what time, and what the weather was doing. Emergence points are how an inspector maps the likely route back to the colony.

  5. 05 The piles mark flight paths

    Leave the shed wings alone

    Termites drop their wings minutes after landing, and the piles on sills and in cobwebs mark flight paths. Note where they collect before anyone vacuums.

  6. 06 Containing the room is enough

    Close the door and let it end

    Swarmers cannot bite, sting, or chew your framing, and indoors they almost never survive to start anything.

  7. 07 A swarm indoors qualifies without debate

Grade level

Swarmers that emerged through a register came from inside the envelope. That means workers already have a route, and the route starts down here.

Why a 40 minute event is the loudest signal a house can send

Swarms are short. Most wind down in well under an hour, and by evening the only trace is wings and a few dead stragglers. That brevity fools people into shrugging it off, which is exactly backwards. Swarmers are reproductives, and colonies of the eastern subterranean termite typically need several years of growth before they produce any. A swarm is not an early warning. It is a mature colony announcing itself.

OutdoorsOff a stump or fence line

Spring background noise Common across Hampton Roads from March through June, usually on a warm humid morning after rain.

IndoorsThrough a register or baseboard

Inside the envelope Workers already have a route into the structure. Our mild termite season produces outliers, so timing does not excuse it.

What happens after you call

An inspector walks the room where they emerged, then the crawl space or slab perimeter under it, looking for mud tubes, damaged wood, and the moisture conditions that fed the colony. You get a straight answer about what was found and where. If the colony is confirmed, the fix in our market is usually a liquid soil treatment, and the inspection tells us whether that is warranted at all.

The one move that costs people real money is waiting until next spring to see if it happens again. It will, and the workers will have been eating the whole time. Bag the samples, take the photos, and make the call the same day.
