Will the council remove a wasp nest in my New Plymouth garden?

No. The district council says it doesn't manage nests on private property. It does want to hear about nests in public parks and reserves.

Are there Argentine ants in New Plymouth?

We couldn't confirm it. DOC's list of places where they're known doesn't name Taranaki, so if you see wide trails of small honey-brown ants, have them identified.

When do wasps peak in New Plymouth?

The council treats February and March as the German wasp breeding season, and that's when it runs its baiting. A nest you find then has usually been growing for months.

What's different in New Plymouth

Rats, counted every year

Towards Predator-Free Taranaki tracks rats at the same 10 sites across the city, with inked cards left in baited tunnels for one night. RNZ reported that 11 percent of cards showed rat tracks in 2025, down from 16 percent the year before and 36 percent in 2018.

Traps in one in five backyards

More than one in five households had a backyard trap, RNZ reported, and almost 4000 rats were logged as caught in the city in 2024. The district council traps public spaces, where more than 100 volunteers check about 1,500 traps across 2,000 ha of parks and reserves.

Wasp baiting stops at your boundary

The council baits wasps at about 50 sites on public land, from Ōkato to Urenui and inland to Inglewood, in February and March, the German wasp breeding season. It doesn't manage nests on private property, but wants to hear about nests in parks or reserves.

Mynas in the eaves

Common mynas live throughout the North Island north of 40 degrees south, and nest in cavities, including inside house eaves.

Sunny and windy

NIWA describes Taranaki as generally sunny and windy, with a good supply of rain spread evenly through the year.

Fewer rats in the count, but one in your roof?

A falling city count is good news, but it comes from one night at 10 sites. It can't tell you what's in your ceiling. Scratching at night, droppings and teeth marks mean it's time for someone to find how they're getting in.

A backyard trap and a pest business do different jobs. The trap catches what passes through the garden; the business closes the gaps that let rats into the house.

Finding the wasp nest, from a distance

The council says wasps forage up to 200 m from their nest, so the line they fly can lead you to it. Watch from well back and don't follow them close. DOC says German wasp nests are grey and common wasp nests brown.

Once you know roughly where it is, keep people clear and pass it to a pest business. A nest in a public park goes to the council instead.

Ant trails in New Plymouth

DOC's list of places with Argentine ants doesn't include Taranaki, which isn't the same as saying they're absent. If a trail is wide and the ants are honey-brown, ask for them to be identified. DOC says potted plants carry the highest risk of spreading them, so look over new plants before they go in the garden.

What you can do, and what's theirs

You can

Keep compost rat-proofed and pet food put away at night.
Watch where wasps fly, from a long way back.
Note where mynas go in and out of the eaves.
Check new potted plants for ant trails.

Leave to a pest business

Rats or mice inside the roof or walls.
Any wasp nest on your property.
Bird proofing (screens or covers over gaps in the eaves).

Our take on pests in New Plymouth

Keep the backyard trap, and don't expect it to fix a problem that's already indoors. Scratching in the roof, a nest by the path and birds in the eaves are three different jobs, so tap the one you've got and tell the business what you've noticed.
