Common NZ Pest Issues
Wasps
German and common wasps are a serious summer problem across NZ, particularly in Nelson/Marlborough and the Waikato. Nests in wall cavities, under eaves, and in the ground can contain 10,000–50,000 wasps at peak. Never attempt to remove a wasp nest without protective equipment — the risk of anaphylactic shock from multiple stings is real. A pest controller removes nests safely for $150–$600.
Rodents
Rats and mice enter homes as temperatures drop in autumn and winter. Signs include droppings, gnaw marks, scratching sounds in walls/ceiling, and nesting material. A 3-month baiting programme (visit + monitoring) typically costs $250–$500 and provides ongoing control. Seal entry points as part of any rodent programme.
Cockroaches
German cockroaches (small, found in kitchens and bathrooms) are harder to eradicate than American cockroaches. They require gel baiting combined with insect growth regulator — multiple visits over 6–8 weeks. A single spray visit is not sufficient; expect a 3-visit programme for German cockroaches.
Bed Bugs
Bed bugs are increasing in NZ, particularly in rental properties and accommodation. Heat treatment (raising room temperature to 55°C+) is the most effective method and costs $600–$2,000 per room. Chemical treatment is cheaper but requires multiple visits and thorough preparation. This is not a DIY job — over-the-counter products rarely achieve full elimination.
Borer
Native borer (Anobium borer) attacks untreated timber in older NZ homes. Signs include small round holes and fine powder on timber surfaces. Treatment involves applying boron-based products to all exposed timber — a significant job in a whole-house application ($600–$3,500). Roof void, subfloor, and exposed structural timber all need treatment.
DIY vs Professional Pest Control
DIY is adequate for: - Ant baits (Raid or Ant Sand for minor ant trails) - Fly and wasp surface sprays in accessible areas - Rodent snap traps in lightly infested situations
Professional is required for: - Any wasp nest removal - German cockroach infestations - Bed bugs - Borer (product strength and coverage not available to the public) - Possum control (possums are protected under the Wildlife Act — a permit is required for lethal control; only licensed operators can trap and relocate)
