Termite Swarmers vs. Flying Ants: Which Did You Just Find?
Every spring, SGV windowsills collect little piles of wings. Here's the 10-second check that tells you whether to relax — or book an inspection.
Look at the waist first. Ants have a pinched, hourglass waist; termite swarmers are straight-sided, like a grain of rice with wings. Then the antennae: ants' are bent at an elbow, termites' are straight and beaded. Finally the wings: ants have two visibly different sizes; termite wings are all equal length, and nearly twice the body.
The biggest tell: shed wings
Termite swarmers drop their wings minutes after landing — it's step one of starting a new colony. Little piles of identical wings on a windowsill, in a spider web, or by a door track, with no insects in sight, point strongly to termites. Flying ants keep their wings.
What finding them indoors means
Swarmers only launch from established, mature colonies. A handful indoors that came in through an open door on a warm evening is one thing — but swarmers or wings emerging inside, especially near baseboards, window frames or the garage, usually means the colony is in the structure. Both drywood and subterranean termites swarm here in the SGV, typically on warm, still afternoons after rain.
What to do (and not do)
Don't spray the area — you'd kill a few swarmers and erase the evidence while the colony keeps chewing. Instead, collect a few insects or wings in a zip-top bag and note where you saw them. Identification determines everything, because drywood and subterranean treatments are completely different. Our termite inspections sort it out, the work is warranty-backed, and if they turn out to be flying ants, that's a much easier conversation: (626) 409-1584.

How can I tell termite swarmers from flying ants?
Three checks: termites have straight bodies, straight beaded antennae and four equal-length wings. Ants have pinched waists, elbowed antennae and two different wing sizes. Piles of shed wings with no insects point to termites.
I found wings but no insects. What does that mean?
Termite swarmers shed their wings minutes after landing, so wing piles on sills and door tracks are a classic termite sign — worth a professional inspection even though the insects are gone.
When is termite swarm season in the San Gabriel Valley?
Mostly spring — warm, still afternoons after rain, roughly March through May — though drywood termites can also swarm in late summer and fall here.
