Silver Bullet Pest ControlA cloud of winged insects by a basement window, or a pile of tiny wings on the sill? In New Jersey that is either flying ants or termite swarmers, and the difference matters: one is usually a nuisance, the other is a sign termites are living in or under your home. Here is a quick way to tell them apart, what each one means, and what to do today.

Catch one (tape works), take a close-up photo and text it to 973-510-2585. We'll tell you what it is.
To tell flying ants from termite swarmers, look at three things: termite swarmers have a thick, straight waist, straight antennae and four wings of equal length that break off easily, while flying ants have a pinched waist, bent (elbowed) antennae and front wings longer than the back wings. In New Jersey, termite swarmers indoors usually mean an active termite colony in or under the house, so they call for an inspection. Flying ants can mean a nest nearby, and carpenter ants deserve a closer look. Text a photo to 973-510-2585 and we'll identify it.
Use this table with a magnifying glass or a zoomed-in phone photo. Two or three matches in one column is usually enough:
| Feature | Termite swarmer | Flying ant |
|---|---|---|
| Waist | Thick and straight, no pinch — body looks like one tube | Narrow, pinched waist between thorax and abdomen |
| Antennae | Straight, like a string of tiny beads | Bent at an angle (elbowed) |
| Wings | Four wings, all about the same length, about twice as long as the body | Four wings, front pair clearly longer than the back pair |
| Wing look | Milky or smoky, with a fine net of veins | Clearer, with fewer, stronger veins |
| Shed wings | Drop off very easily — piles of loose wings on sills and floors | Stay on longer; you'll see fewer loose wings |
| Color (NJ) | Eastern subterranean swarmers are dark brown to black | Black, brown or reddish, depending on the species |
| Size | Small, roughly 3/8 inch including wings | Ranges from tiny to over half an inch (carpenter ant swarmers are large) |
| Where you find them | Near windows, doors and light, often in the basement or a sunny room | Near windows and lights, or outdoors around a nest |
Found only wings? Termite wings are all the same size and look like tiny, cloudy fish scales. See termite wings in the house.
If you only remember one thing from this page, remember these:
Ants are built like an hourglass with a tiny waist. Termite swarmers are straight from head to tail, almost like a grain of rice with wings.
Ant antennae bend like an elbow. Termite antennae are straight and soft-looking, curving gently but never bending sharply.
Lay the insect flat. If all four wings are the same length, it's a termite. If the front wings are longer, it's an ant.
Termites shed their wings right after swarming. Lots of loose, identical wings with few bodies is a strong termite sign.
Keep a sample. A few insects on a piece of clear tape, or in a sealed bag in the freezer, help the inspector confirm what you saw.
These are the reproductive termites leaving a mature colony to start new ones. When they swarm inside, the colony is usually in the soil under the house or already in the wood. Swarmers themselves don't eat wood or bite; the workers you don't see do the damage.
Carpenter ants don't eat wood, but they hollow out damp or damaged wood for nests. Swarmers inside, especially in late winter or early spring, can mean a nest inside the house. We can treat the nest and repair damaged wood.
Small ant species send out swarmers from outdoor nests, under slabs and along foundations. A swarm by a sidewalk crack or patio is common and rarely a threat to the house, but repeated indoor swarms can mean a nest under the floor.
Timing is a clue, but not proof. Both can show up in spring:
| Time of year | Termite swarmers | Flying ants |
|---|---|---|
| Late winter | Possible indoors in heated basements and boiler rooms | Carpenter ant swarmers indoors can mean a nest inside |
| Spring (roughly March to May) | Peak season, often on a warm, sunny day after rain, usually late morning to midday | Carpenter ants and several small species begin swarming |
| Summer | Less common | Many ant species swarm, often in the afternoon or evening |
| Fall | Uncommon | Some species swarm; often seen around foundations after rain |
Swarms usually last less than an hour. The insects may be gone by the time you get back with a camera, but the wings stay behind.
This is the one to take seriously. Termite swarmers come from a colony that is several years old and large enough to send out reproductives. If they emerged inside — from a baseboard, a slab crack, a door frame or a window sill — the colony is usually in the soil under the home with a route into the wood, or already in the framing. The swarmers themselves die quickly indoors, but the workers keep feeding.
It is not an emergency in the sense of minutes or hours, but it is a call-this-week problem. Termite damage builds quietly, and the sill plates and joists along the foundation are usually the first to go. Look for mud tubes on the foundation while you wait.
A swarm in the yard, from a stump, an old fence post or a woodpile, means termites are on the property, not necessarily in the house. It's still worth an inspection, especially if you've never had one or the house was treated many years ago.
Small ants swarming indoors often have a nest under a slab, in a wall void or just outside. They are a nuisance. Carpenter ant swarmers are different: they can mean a nest inside the structure, often near a roof leak, a damp window frame or a bathroom. Read signs of carpenter ants in the house.
Ants swarming from a lawn, patio or sidewalk is normal and usually nothing to treat unless they are getting in the house.
Press a few insects onto clear tape or put them in a sealed bag. Also save some loose wings.
A window, a baseboard, a crack in the floor, the fireplace? The exact spot helps us find the colony's way in.
Swarmers are harmless to people and pets. Vacuum them up; spraying them doesn't solve anything because the colony isn't in the room.
Send a close-up to 973-510-2585. If it's termites, we'll set up an inspection; if it's ants, we'll tell you whether it needs treatment.
Don't tear open walls or flooring looking for the source. An inspector can usually find it with less damage.
Identification is the first step, not the last. When we come out after a swarm, a licensed technician:

If the swarm came from inside the house, it usually means an active colony is in or under the home. A swarm outdoors, from a stump or woodpile, means termites are on the property. Both are good reasons for an inspection.
No. Swarmers are winged reproductives looking to start a new colony, and they die quickly indoors. The damage comes from worker termites that stay hidden in the soil and wood.
The swarmers die off within hours to a day or so indoors, but the colony that produced them stays. That's why a swarm that 'went away' still needs an inspection.
Most flying ants are harmless to the structure. Carpenter ants are the exception: they hollow out damp wood for nests, so carpenter ant swarmers indoors should be checked.
Termite swarmers drop their wings right after they land, then crawl off or die. Piles of identical wings by windows and doors are a classic termite sign.
Termite swarmers don't bite people. Flying ants rarely bite and are not dangerous. Neither one spreads disease.
Mostly in spring, roughly March through May, often on a warm day after rain. In heated homes, swarms can happen as early as late winter.
Spraying swarmers doesn't help, because the colony isn't in the room. Vacuum them up, save a few samples and call for an inspection.
Yes. We treat termites and carpenter ants, and our own crew repairs termite-damaged wood after treatment. We can also repair wood damaged by carpenter ants.
We're based in Garfield and serve Bergen, Passaic, Essex and Hudson counties, plus Morris and Union counties with visits scheduled ahead.
Las termitas tienen la cintura recta y cuatro alas del mismo tamaño; las hormigas tienen la cintura delgada y las alas delanteras más largas. Mándenos una foto al 973-510-2585 y le decimos qué es.
Based in Garfield, we identify and treat termites and ants across North Jersey.
