Termites vs ants comes down to three things you can check with your phone’s camera. Termite swarmers have straight antennae, a thick waist and four wings of equal length. Flying ants have bent, elbowed antennae, a pinched waist and front wings that are longer than the back ones, according to Mississippi State University Extension.
It matters because the answer changes what you do next. Termite swarmers indoors mean the building is infested and needs professional treatment, Mississippi State says. Flying ants can often be handled for much less.
Termites vs ants at a glance
| Feature | Termite swarmer | Flying ant |
|---|---|---|
| Antennae | Straight, like a string of beads | Bent at an elbow |
| Waist | Thick, no pinch | Narrow, pinched |
| Wings | Four of equal length, about twice the body length, pale and see-through | Front wings longer than back wings, often tinted brown |
| Body color | Black to dark brown | Black, brown, reddish or tan |
| Workers | Creamy white and rarely seen outside the colony | Never have wings |
| What it does to wood | Eats it and packs tunnels with mud | Carpenter ants chew it out for nests and leave sawdust |
The details come from Mississippi State, the University of Maryland Extension, Penn State Extension and the University of Connecticut.
How to check what you found
- Look at the waist. A pinched waist like a wasp’s means ant. A thick, straight body means termite.
- Look at the antennae. An elbow means ant. Straight means termite.
- Look at the wings, if they’re still on. Equal length means termite. Long front wings and short back wings mean ant.
- Check the windowsill. Piles of shed wings, all the same size, are a classic termite sign. Both can drop their wings, though, so look at the bodies too.

When each one swarms
In New York, the eastern subterranean termite swarms from about March through June, according to Cornell Cooperative Extension of Nassau County, often near windows and doors because swarmers are drawn to light. Ants swarm too, including carpenter ants, the large black ants that also live in wood. A carpenter ant swarmer is bigger, about 1/2 to 3/4 inch long, according to the University of Connecticut, while termite swarmers are about 3/8 to 1/2 inch with their wings.
Termite damage vs carpenter ant damage
Both can damage wood, but in different ways:
- Termites eat the wood. Their tunnels follow the grain and are lined or packed with mud, and you’ll often find mud tubes on the foundation or basement walls.
- Carpenter ants don’t eat wood. They chew it out to make nests and push out small piles of sawdust. They prefer wood that’s already damp, like a leaky window frame, a sweating pipe or a soft spot on a deck, the University of Connecticut notes.
Carpenter ant damage is usually much less severe than termite damage, UConn says. But both point to a moisture problem worth fixing.
What we see in NYC buildings
Here’s a simple example. Say a tenant in a Queens two-family house finds a cluster of winged insects on the kitchen windowsill in May. The landlord assumes they’re ants. A close-up photo shows straight antennae, thick waists and wings longer than the body, all the same length. Those are termite swarmers, and the windowsill is just where they came to the light. The colony is in the soil, and the place to look is the basement: the sill plate, the stairs and any wood near the floor.
Our advice: don’t guess, and don’t just vacuum them up. Save a few in a zip-top bag or take a sharp photo. Confirming whether it’s termites or ants is part of every termite inspection we do.
If they’re termites, read the signs of termite damage and how to get rid of termites, or learn about the termite life cycle. NYC Extermination’s inspection is free, and we confirm it’s termites and not ants or another wood pest before anything else. See our termite control service or call (347) 988-2315.
Frequently asked questions
How can you tell if it is a termite or an ant?
Check the waist first. Ants have a narrow, pinched waist, and termites don’t. Then check the antennae: bent means ant, straight means termite. If wings are still attached, termite wings are all the same length.
Are flying ants a sign of termites?
No. Flying ants are ants. But they’re easy to confuse with termite swarmers, and both show up in spring, so check before you decide. If they’re termites, the building needs an inspection.
Do carpenter ants eat wood like termites?
No. Carpenter ants chew out wood to build nests and leave sawdust behind, but they don’t eat it. Termites eat wood and leave mud, not sawdust. Carpenter ants also prefer wood that’s already damp.
