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 Ashburton: what to know before anyone calls

Wasps close to the house
Keep back from any nest and bring the kids and dogs inside until you know where it is. Anyone with a swollen face, wheezing or a tight throat after a sting needs 111. The National Poisons Centre on 0800 764 766 can advise on a sting at any hour.
What's different around Ashburton
Plains weather
NIWA says the Southern Alps shape every part of Canterbury's climate. The plains get low rainfall, with winds mostly from the north-east and south-west.
Hot spells
During foehn episodes, NIWA says, summer maximums often pass 30°C throughout Canterbury. Those are the stretches when wasps are busiest around food and water.
Wasp years in Mid Canterbury
In February 2009 RNZ reported ten wasp nests near Methven's primary school, with pupils kept inside at lunchtime. The principal said the town is plagued every four to five years, and a local pest business blamed the hot weather after dealing with more than 18 nests in a few weeks.
Canterbury's pest plan
Environment Canterbury's Canterbury Regional Pest Management Plan 2018 to 2038 covers the district. It lists three animals as pests: feral rabbits, feral goats and possums. Rats are watched as organisms of interest rather than declared.
Two councils
Ashburton District Council looks after district matters, and Environment Canterbury the regional plan. For a nest or rats on council land, ring the district council.
Rats and mice around the shed
On the edge of a farming town, rats go where the feed is. Christchurch City Council's parks plan notes that rats scavenge stored grain, fruit and refuse, and the EPA says one female rat has 15 to 20 babies a year. A few in the shed in autumn can be a lot more by spring.
Tenancy Services says winter is a more common time for rats and mice to get into the house. Health NZ says rodents carry disease and contaminate food, and lists them among the animals that can pass on leptospirosis. Cover any cuts before you clear out a shed they've been in.
If you've found a wasp nest
Get everyone clear
Shut nearby doors and windows, and move the outdoor table away from the flight line.
Watch from a distance
Wasps flying in and out of one spot give the nest away. Banks, the base of flax clumps and gaps under the roof edging are common places.
Work out whose land it's on
On your own section it's yours to arrange. On a reserve or roadside, ring Ashburton District Council.
Tell us where it is
Tap A wasp nest and describe the spot. A photo from well back helps the pest business plan.
Other jobs worth knowing
Fleas come in on pets and turn up in carpets and pet bedding. White-tails wander indoors in late summer and autumn, and one on the wall isn't worth paying for. If you see mud packed into gaps in timber, that's not a pest business call: leave it alone and ring MPI.
Where we'd start with pests in Ashburton
If it's wasps, we'd get the nest's location sorted before anything else, because a hot week makes a busy nest busier. If it's rats, we'd put feed and grain into sealed bins first, then get a pest business to look at how they're getting in. A tidy shed helps whatever treatment follows.

Questions
Pest control in Ashburton: common questions
Is this a bad wasp year?
We can't say for this summer. Methven's principal told RNZ in 2009 that the town gets plagued every four to five years, and long, hot, dry summers are when numbers climb.
Do I have to tell anyone about rats on my property?
Canterbury's regional plan watches rats rather than declaring them pests, so there's no regional rule to report them. On your own section they're yours to deal with.
