First, stay back
Leave the nest alone and keep children and pets clear, even if the entrance looks small. Swelling around the lips or eyes, wheezing or a tight throat after a sting means call 111. The National Poisons Centre gives advice on 0800 764 766 at any hour.
Wasp nests in Christchurch: what's different
On private or council-leased land
The council points you to the Christchurch Hobbyist Beekeepers' Club, who may be able to help with nests and swarms, or to a pest controller. In practice a wasp nest beside the house goes to a pest business.
In a park or other council-maintained area
Ring the council. Give the park's name and a landmark so someone can find it.
A complaint needs an address
The council says it won't investigate unless a complaint is tied to specific premises. If you think the nest is on a neighbour's place, work out which property from a good distance before you ring.
Most likely a German or common wasp
DOC places Asian paper wasps in the North Island and the top of the South Island, so an enclosed nest is the likelier find here than the open combs you'd see further north.
Hot, dry spells
NIWA says foehn winds often push Canterbury's summer maximums past 30°C, and the plains get low rainfall. A long, dry, hot summer built wasp numbers up in 2025, a University of Auckland professor said, so don't be surprised by a busy late summer after a dry one.
Where nests hide on a Christchurch section
Wasps usually nest in the ground, but they're not fussy. The Tasman and Nelson councils' insect booklet lists banks and the base of flax or grass clumps, and roofs where wasps slip in under corrugated iron edging at the guttering.
A steady line of wasps heading to one spot is the clue to look for. You'll see it from a long way back, and that's the place to watch it from. Grey nests are German wasps and brown nests are common wasps, DOC says, though it won't change who you ring.
Is it a nest or a swarm?
A cluster of honey bees hanging off a fence or branch is a swarm, and that's for a beekeeper rather than a pest business. Apiculture New Zealand says to leave it alone and not to spray it, and lists swarm collectors by region. Their season can start as early as August and runs to January. Bees that have moved into a wall or roof are a different matter.
What's yours, and what isn't
You can
- Keep doors and windows near the flight line shut.
- Cover food and drink outside.
- Take a photo from a long way back.
- Warn the neighbours if it's near the boundary.
Leave to a pest business
- Anything to do with the nest itself.
- Nests in ceilings, walls, banks or the ground.
- Anything that needs a ladder.
Good questions for the pest business
- Which product will you use, and what's its full name?
- If the nest is in the ceiling, how will you get to it?
- How long should we keep kids and pets away from the area?
- What should we do if wasps are still about in a few days?
Our take on wasp nest removal in Christchurch
We'd stop mowing near it, get everyone inside and photograph the flight line from well back. Then we'd tap A wasp nest and say exactly where it is. On your own section there's no council step to wait for, so the sooner the pest business knows, the better.
