The quick answer
A cloud of winged insects around your outdoor lights on a warm spring evening — or little piles of shed wings on the windowsill — usually means termite alates: winged termites leaving a mature colony to start new ones. The swarm itself won’t hurt your house. What it’s telling you matters enormously: an established termite colony is close — typically within about 50 to 100 metres. That could be a tree stump, a fence line, a neighbour’s yard… or your own walls. The right response isn’t panic, and it isn’t fly spray — it’s a proper termite inspection.
What you’re actually seeing
Every spring — October through December in Melbourne, peaking mid-October to early November — mature termite colonies release thousands of winged reproductives. They fly badly and briefly, they’re drawn to lights, they drop their wings, and the survivors pair off to found new colonies. Warm, humid evenings after rain are prime swarm weather. If your place lit up like a bug disco one night and it was over by morning, that’s the classic pattern.
Termite or flying ant? The 10-second check
Grab one (they’re harmless) or photograph a few, and look at three things. Antennae: termites have straight antennae; ants have elbowed ones with a bend. Wings: termites carry two pairs of equal-length wings, longer than their body; ants have mismatched pairs — long front, short back. Waist: termites are thick-waisted, ants are pinched like an hourglass. Straight antennae + equal wings + no waist = termite. Either way, if you’re unsure, send us a photo when you call.
Wings inside the house? That’s the serious version
Shed wings on outside sills and around porch lights usually means a colony somewhere in the neighbourhood. Piles of wings inside the house — on internal windowsills, in the garage, along skirting boards — can mean the swarm emerged from within your own walls. That’s a book-the-inspection-this-week situation, not a keep-an-eye-on-it one. Phones are answered 7am–9pm on (03) 9436 0883, and we treat termite calls as urgent.
What to do (and what not to bother with)
Don’t waste a can of spray on the swarm — the flyers die on their own within a day and the colony that sent them doesn’t notice or care. Vacuuming them up is fine. What’s worth doing: note roughly where they seemed to come from (a stump? the fence? under the deck? inside?), grab a photo, and book an inspection so we can find the colony behind the show. And if you spot mud tubes or live termites while looking around — stop there and read what to do when you’ve found termites: don’t disturb them.
Spring is exactly when to check your home’s protection
A swarm in your street is the neighbourhood’s annual reminder that colonies are active nearby. If your home has never had termite protection — or you don’t know whether it has — spring is the smart time to find out, before the season peaks. Our inspections establish exactly that, and homes near bushland, creeks and established gardens should treat it as annual routine: our runs through St Helena, Eltham, Montmorency and the leafier belts stay busy every spring for a reason. The full picture of protection options is on our termite control page.
Flying termite questions
Are flying termites dangerous?
Not directly — they don’t bite, sting or eat your timber. Their entire job is starting new colonies. The danger is what they signify: a mature colony operating within about 50 to 100 metres, and thousands of would-be colony founders landing around your property.
Does a swarm mean my house has termites?
Not necessarily — the colony could be in a stump, a tree or a neighbour’s yard. But it does mean active termites are close enough that your home needs checking, especially if you found shed wings inside the house, which can indicate the swarm came from within your walls.
Can I just spray them?
You can, but it achieves nothing — the flyers die within a day anyway, and the colony that released them is untouched somewhere else. Spend the effort on an inspection instead; that’s the response that actually protects the house.
How do I tell a flying termite from a flying ant?
Termites: straight antennae, two pairs of equal-length wings longer than the body, thick waist. Ants: elbowed antennae, unequal wing pairs, pinched waist. Photograph one and send it through if you’re not sure.
When is termite season in Melbourne?
Swarms fly October to December, peaking mid-October to early November, usually on warm humid evenings after rain. Termites themselves are active year-round — the swarm is just the once-a-year moment they’re visible.
