Flying Termites or Flying Ants? How to Tell the Difference
It happens every fall in Vallejo. The first real rain comes through, the sun comes out the next day, and suddenly there are winged insects around a window, a light or the garage door. Are they termites or ants?
The answer matters. Flying ants are usually a nuisance. Flying termites can mean a colony is already feeding on your home. You can tell them apart in about 30 seconds if you know what to look at.

The 3 quick checks
Catch one in a jar or on a piece of clear tape and look closely. A phone camera zoomed in works too.
1. Antennae
- Termite: straight antennae, like a string of tiny beads.
- Ant: bent antennae, with a clear elbow in the middle.
2. Waist
- Termite: thick, straight body with no real waist. The body looks like one long piece.
- Ant: a very narrow, pinched waist between the chest and the abdomen.
3. Wings
- Termite: two pairs of wings that are the same length, longer than the body, and break off easily. They look milky or smoky.
- Ant: two pairs of wings of different lengths. The front pair is clearly longer than the back pair. Wings stay on more firmly and are clearer.
If it has straight antennae, a thick waist and equal wings, it is a termite.
Side-by-side comparison
| Flying termite (swarmer) | Flying ant | |
|---|---|---|
| Antennae | Straight, beaded | Bent, elbowed |
| Waist | Thick, no pinch | Narrow, pinched |
| Wings | Two pairs, equal length, longer than body | Two pairs, front wings longer than back |
| Wing color | Milky, grayish or smoky | Clear or lightly tinted |
| Wings after landing | Fall off quickly, left in piles | Usually stay on longer |
| Body color | Dark brown to black, or pale reddish-brown | Black, brown or reddish |
| Common sign left behind | Piles of identical wings near windows and doors | Ants walking in trails |
Why both swarm in the first place
Swarming is how both termites and ants start new colonies. Winged males and females, called alates or swarmers, leave the nest in big numbers, mate, drop their wings and try to start a new colony.
A swarm indoors means the swarmers likely came from inside the structure or very close to it. That is why an indoor termite swarm is a big warning sign.
When they swarm in Vallejo
Timing is a strong clue in our area:
- Western subterranean termites: the day after the first good fall rain, usually October or November, on a warm, sunny morning or midday. They can also swarm on warm spring days after rain.
- Western drywood termites: warm, sunny afternoons from late summer into fall, often after a hot spell. They come out of attics, eaves, window frames and fascia boards.
- Dampwood termites: late summer and fall evenings, attracted to lights.
- Flying ants: spring and summer for many species. Carpenter ants and other ants can swarm on warm days in spring.
Many swarms we hear about in Vallejo happen right after that first big storm of the season. If you see winged insects around a window in late October, check them before you sweep them up.
Found wings but no insects?
Termite swarmers drop their wings within minutes of landing. A small pile of identical, see-through wings on a windowsill, in a spider web or near a door is one of the clearest termite signs there is. Ant wings are less often left in piles.
Collect a few wings in a sealed bag before you clean. It helps with identification during an inspection.
What to do if they are termites
- Do not panic, and do not spray them. Killing the swarmers does nothing to the colony.
- Collect a few samples in a sealed bag or on tape.
- Note where they came from: a window frame, baseboard, attic hatch, garage wall or crawl space vent.
- Look for other signs like mud tubes on the foundation or pellet piles under wood. Our signs of termites guide has a full checklist.
- Book an inspection. Call (707) 000-0000. A termite inspection tells you whether you have drywood or subterranean termites, where the colony is and what treatment fits.
Our termites in Vallejo guide explains drywood vs subterranean termites, and our termite control in Vallejo page covers inspection, treatment and tenting.
What to do if they are flying ants
Flying ants indoors can still mean a nest in or near the house, especially if they keep coming out of the same spot. Carpenter ants, for example, nest in damp or damaged wood.
- Seal gaps around windows, doors and pipes.
- Fix moisture problems and replace rotted wood.
- Watch for ant trails afterward, which point to the nest.
If ants keep showing up, our ant control in Vallejo page explains how we treat the colony. For why ants pour into Vallejo homes in the rainy season, see why ants invade after rain.
Flying ants vs termites: common questions
How can I tell flying ants from termites?
Look at three things. Termites have straight antennae, a thick waist and four wings of equal length. Flying ants have bent antennae, a pinched waist and front wings that are longer than the back wings.
Are flying termites a sign of infestation?
A swarm inside the house usually means there is an active colony in or right next to the structure. A swarm outside, far from the house, is less certain but still worth an inspection.
Do flying termites bite?
No. Termite swarmers do not bite or sting people. The concern is the colony they came from.
What time of year do termites swarm in Vallejo?
Subterranean termites swarm after the first fall rains and on warm spring days after rain. Drywood termites swarm on warm, sunny days in late summer and fall.
Why are there wings on my windowsill?
Termite swarmers shed their wings soon after landing, and they are drawn to light, so wings collect on windowsills and near doors. Piles of equal-sized wings are a strong sign of termites.
Should I spray flying termites?
Spraying kills the swarmers you can see but does nothing to the colony inside the wood or soil. Collect a few for identification and book an inspection instead.
How long does a termite swarm last?
A swarm usually lasts from a few minutes to under an hour. You may see more than one swarm over several days or weeks.
