What a termite swarm is
Winged termites (called alates, or swarmers) are the reproductive members of a mature colony. When conditions suit them, a colony releases large numbers of them to fly off, pair up and start new colonies. They're weak fliers, they're drawn to lights, and they shed their wings soon after landing. That's why the usual sign is a pile of similar-sized wings near windows, lamps or door gaps.
Swarmers themselves don't damage wood. What matters is where they came from.
Flying termites or flying ants?
| Termite swarmer | Flying ant | |
|---|---|---|
| Antennae | Straight, like a string of beads | Bent at an "elbow" |
| Waist | Thick, with no clear pinch | Narrow, pinched waist |
| Wings | Two pairs of roughly equal length, longer than the body, shed easily | Front wings noticeably longer than the back wings |
If you're not sure, keep a few insects or wings in a sealed bag or on clear tape and take close-up photos. An operator can identify them quickly.
What a swarm indoors can mean
- Swarmers coming out from inside the home, for example from a skirting gap, door frame, cabinet or a crack in the wall, suggest there may be a colony or active termites in or under the home. This is the case to take seriously.
- A few swarmers that flew in through an open window towards the lights may have come from outside. That doesn't confirm an infestation in your home, but it does mean there's a colony somewhere nearby.
- Repeat swarms in the same spot, or wings found in the same corner more than once, point to a source close by.
What to do tonight
- Switch off the lights in the room and close windows. Swarmers head for light. They can't start a colony on a dry floor, and ones that don't find shelter soon die.
- Vacuum or sweep up the insects and wings, but keep a sample in a sealed bag first.
- Note where they seemed to come from: a particular gap, frame, cabinet or window. Take photos.
- Don't spray inside walls, frames or cabinets. Killing swarmers doesn't affect the colony, and spraying where termites may be active can drive them elsewhere and make the operator's job harder.
What to check over the next few days
Look near where the swarm appeared, and around the home:
- Mud tubes on walls, skirting, pipes or the backs of cabinets
- Door frames, kitchen cabinets, built-in wardrobes and timber or parquet flooring that sound hollow when tapped
- Small piles of dry, pellet-like droppings under wooden furniture or frames, a sign of drywood termites
- Bubbling paint or laminate, and doors or drawers that have started to stick
Our guides on signs of termites in an HDB flat and termites in wooden furniture show where to look in more detail.
Flats, condos and landed homes
- HDB flats and condos: swarmers can come from your unit, a neighbour's unit or common property. If the source seems to be a corridor, riser or shared wall, let your Town Council or management office know as well. See termite treatment for HDB flats and termites in a condo.
- Landed homes: check the base of the house, garden timber, decking, planters and the roof space if you can reach it safely.
When to call an operator
Get an inspection if swarmers came from inside the home, if you find any of the signs above, or if swarms keep coming back. A licensed operator will identify the species, find where they're coming from and recommend a method, which for subterranean termites is often baiting or soil treatment and for drywood termites is usually local treatment inside the timber. Check that the company is a registered Vector Control Operator on NEA's list.
What it costs (indicative)
- Inspection: free at some operators. KakiList notes some providers charge a S$30–50 site-visit fee (KakiList, Pest Control Cost in Singapore (2026), updated Apr 2026).
- Baiting with monitoring: from S$700 per year. Drywood foaming: from S$300 (Rentokil Singapore, Termite Treatment Price in Singapore).
- Termite corrective work with a warranty: S$800–1,800 for HDB flats, S$1,200–2,800 for condos and S$2,500–5,500 for landed homes (KakiList, Pest Control Cost in Singapore (2026), updated Apr 2026).
Prices checked on 26 October 2026. These are published ranges and starting prices, not quotes. Your price depends on inspection. More in the termite price guide.
Questions
Do flying termites mean my house has termites?
Not necessarily. Swarmers that flew in towards your lights may have come from outside. But if they came out of a gap, frame or cabinet inside your home, or you keep finding wings in the same spot, get an inspection.
Do flying termites eat wood?
Swarmers don't damage wood themselves. They leave the colony to start new ones. The damage is done by worker termites in an established colony, which is why it's worth finding where the swarmers came from.
Should I spray the flying termites?
There's little point. Swarmers die quickly without shelter, and spraying them doesn't affect the colony. Switch off the lights, sweep them up, keep a sample and avoid spraying inside walls or carpentry before an inspection.
