Matched to what you've seen
Before a pest business can take jobs from Which Pest, we record the work it handles, so a borer job never lands with a business that only does wasps.

Pest control in Hamilton: what to know before anyone calls
On this page
If there's a nest near people
Keep children and pets back and leave the nest alone. If someone's lips or eyes swell, or they start wheezing or their throat tightens after a sting, call 111. Waikato Regional Council's advice for anyone allergic to stings is plain: don't try to destroy a nest yourself, get a commercial pest control contractor in.
What's different in Hamilton
A wasp rule that can reach your section
Under rule WASP-1 of the Waikato Regional Pest Management Plan 2022 to 2032, occupiers must control common or German wasp nests on their property when directed after a complaint. The Wellington region has a similar rule, and in Waikato a neighbour's complaint can turn your nest into your job.
Half the gullies are private
Hamilton City Council says 50% of the city's gullies are privately owned. If your section drops away at the back, some of that bush may be yours to look after. The council also says to talk to experts or its gully restoration team before you start any predator control.
Cold, damp and foggy in winter
NIWA's table for the Ruakura station averages 21.0 air frosts and 38 days of fog a year, and Hamilton's 9 am humidity averages 84%. They're one station's figures, but they explain a lot about July, which is also when Tenancy Services expects more rats and mice indoors.
Three wasps to tell apart
German and common wasps usually nest underground, and sometimes in hollow trees, walls and roofs. Asian paper wasps were widespread through the upper North Island by 1995, and their bell-shaped nests hang from shrubs and under eaves. Knowing which you've got matters, because the rule names only the first two.
Argentine ants
DOC lists Waikato among the places these ants are known. It calls them a major household and garden pest, and they can bite.
What you're most likely to be dealing with
Rats and mice are the cold-weather job, and scratching above the ceiling at night usually points to rats. Bait and traps around a family home need thought, too: Hamilton City Council says urban predator control needs special care because of the hazards for pets and young children.
Wasps take over through summer. Waikato Regional Council says they mostly hunt for food near the nest, so a steady stream of them at your barbecue usually means a nest within a short flight. Its advice is that dealing with every nest within 200 m of a problem area should make a real difference, and that radius often takes in the neighbours.
Then there's what comes up out of the gully. Hamilton City Council lists possums, rats, mice, hedgehogs, stoats and weasels as predators of native invertebrates, and points residents to Predator Free Hamilton for tutorials and tips. If it's thumping across the roof at night, start with our possum page.
Damp floors and borer
Borer likes damp. Consumer NZ said in 2015 that it prefers moist untreated timber and is often found in floor timbers, so a wet subfloor (the space under a raised floor) deserves a look. Small round holes with fine dust beneath are the giveaway. Buying an older Hamilton house? Settled.govt.nz says to make sure the building inspection covers borer, because some inspectors exclude it.
What if the nest isn't on your section?
On a council reserve or accessway
In the Waikato region, problem nests there go to the city or district council. In Hamilton that's Hamilton City Council, and it should arrange for the nest to be destroyed.
On DOC land
Waikato Regional Council says to tell the nearest DOC office or visitor centre.
Next door
Have a friendly word first, because they may not know it's there. For advice on the wasps or the rule, Waikato Regional Council's pest animal staff can help.
What should you have ready for the technician?
- Whether your section backs on to a gully, and where your boundary runs.
- Where the wasps are flying, watched from well back around dusk on a warm day.
- Any droppings, chewed packets or scratching, and the time of night you hear it.
- A clear path to the ceiling hatch and the subfloor access.
If it were our section in Hamilton
We'd start by working out whose ground it is. A nest on a reserve is the council's to arrange and one on your section is yours, so that single question saves a lot of phone calls. Then we'd tap what we'd seen and leave the inspection to the pest business. If all you've got is a noise at night, Not sure what it is works just as well.

Questions
Pest control in Hamilton: common questions
Do I have to deal with a wasp nest on my Hamilton property?
Waikato Regional Council says occupiers shall control common or German wasp nests on their property, and under rule WASP-1 an authorised person can direct you to after a complaint. If you're allergic to stings, stay away from it and get a commercial contractor, as the council advises.
What if I find mud packed into timber?
Don't disturb it. MPI says mud packed into gaps in timber, or mud tunnels up walls, can be a sign of termites, and it wants to hear about any suspected find. It's a biosecurity report, not a pest job.
