Quick Summary
- Warmer Victorian winters are letting more wasp queens survive — 2026 is shaping up as one of the busiest European wasp seasons yet across Melbourne’s north.
- Nests start small in spring (from September) and grow fast — by late summer a single European wasp nest can hold thousands of aggressive workers.
- European wasps are far more aggressive than paper wasps, sting repeatedly, and are a serious risk to anyone with a venom allergy.
- Nests hide in roof voids, wall cavities, underground burrows, sheds and compost bins around Craigieburn, Kalkallo, Mickleham and Donnybrook homes.
- Never treat a nest yourself — early professional removal is safer and cheaper than a mid-summer job.

Why 2026 is different
Every spring, pest activity climbs as the weather warms — that part’s normal. What’s changed is the maths behind it. A run of milder winters means far more wasp queens are surviving through to spring instead of dying off in the cold. More surviving queens means more new nests, started earlier in the season, in more backyards.
For Melbourne’s northern growth corridor — Craigieburn, Kalkallo, Mickleham, Donnybrook and Greenvale — that’s a double hit. New estates sit right up against open paddocks and grassland, which is prime European wasp territory. Add a warm September and you get nests appearing weeks earlier than families expect, often before anyone’s thinking about pest control.
European wasp vs paper wasp: know what you're dealing with
Not every buzzing insect is a threat, and misidentifying one is the most common mistake homeowners make. Here’s the quick version:
European wasp (the one to worry about)
- Bright yellow and black, roughly the size of a honey bee but without the fuzzy body.
- Builds large, enclosed nests — often hidden underground, in wall cavities, roof voids or compost heaps.
- Aggressive and territorial, especially as the colony grows. It can sting repeatedly.
- Scavenges human food and sweet drinks — which is why it turns up uninvited at the BBQ.
Paper wasp (usually less aggressive)
- Slimmer, longer-legged, with a distinctive thin “waist”.
- Builds a small, open, umbrella-shaped nest with visible cells, usually under eaves, pergolas or in shrubs.
- Will defend its nest if provoked, but is far less inclined to chase you across the yard.
The tell is the nest. An exposed little umbrella of cells is almost always a paper wasp. A steady stream of wasps flying in and out of a single hole in the ground, a wall, or the roofline points to European wasps — and a colony that’s already established.
Where nests hide around northern-suburb homes
By the time most people notice a wasp problem, the nest has been growing quietly for weeks. Common hiding spots include:
- Roof voids and wall cavities — entering through a small gap under the eaves or a weep hole in the brickwork.
- Underground — old rodent burrows, garden beds, and the base of retaining walls.
- Sheds, meter boxes and compost bins — warm, sheltered and rarely disturbed.
- Decks and pergolas — a favourite for paper wasps.
If you can see a consistent flight path — wasps arriving and leaving from the same point — you’ve likely found the nest entrance. Don’t get closer to confirm it.
Why you should never treat a wasp nest yourself
This is the part worth taking seriously. Disturbing an established European wasp nest can trigger hundreds of stings in seconds, and for anyone with a venom allergy that’s a genuine medical emergency. Supermarket sprays only agitate the colony, and blocking the entrance often just sends wasps deeper into your wall or roof looking for another way out — sometimes into the house.
Professionals treat nests safely because timing and product matter. The nest is best treated late in the evening when the colony is home and activity is low, using the right dust or foam delivered directly to the source. It’s precise work with the correct protective gear — not a weekend job.
Prevention: what you can do now
You can’t stop wasps from existing, but you can make your property a lot less attractive before the season peaks:
- Seal gaps around eaves, weep holes, vents and rooflines.
- Clear fallen fruit and keep bins tightly lidded.
- Cover pet food and sugary drinks when outdoors.
- Check sheds, eaves and garden corners early in spring, while nests are small.
- Book a general pest treatment in early spring to create a protective barrier before summer pressure builds.
A small, early nest is quick, cheap and safe to remove. The same nest in February is a very different job.

Frequently Asked Questions
How much does wasp nest removal cost in Melbourne's north?
Cost depends on the nest’s location and size — an accessible nest caught early in spring is far cheaper than an established colony inside a wall cavity in mid-summer. Call us for a quick quote on 0450 480 808.
Are European wasps dangerous?
Yes. They’re more aggressive than most native wasps, sting repeatedly, and pose a serious risk to anyone with a venom allergy. Never disturb a nest yourself.
When is European wasp season in Victoria?
Nests start in spring (from September), grow through summer, and are typically at their largest and most aggressive in late summer and early autumn.
I found a small nest — can I remove it myself?
We don’t recommend it. Even a small European wasp nest can react fast when disturbed. Booking a professional early is safer and usually cheaper than a mid-season treatment.
