Common New Zealand Pests Auckland Regional PEST MANAGEMENT LTD Treat
Aotearoa New Zealand is home to many introduced pests that threaten our native ecosystems, agriculture, and homes. Below is a catalogue of notable pest species found in New Zealand, with images and key facts. Click on each for more detail or to hire management services.
We prioritise targeted, low-toxic methods and integrated pest management (IPM) to protect people, pets, and the environment while achieving reliable control.
Fleas
Can cause health issues for pets and humans, and are difficult to eradicate due to their ability to live in the environment and reproduce quickly
Biscuit Beetle
They infest and feed on a wide range of dried goods, including cereals, flour, pasta, spices, and dried fruits. They also contaminate products with their feces and cast skins, making entire packages inedible.
Weevils
Pasture Damage: Species like the Argentine stem weevil and clover root weevil are major pests of ryegrass and white clover, the foundation of NZ pastures.
Rodents (Rats & Mice)
Norway/ship rats & house mice contaminate food and wiring. Discreet monitoring, proofing, and targeted baits/traps.
Wasps (German & Common)
High-density invaders in NZ; professional nest treatments and baiting programs (seasonal). Do not disturb nests.
Ants (incl. Argentine)
Colonies spread rapidly; we combine baiting with habitat fixes for long-term control.
Cockroaches German
Monitored gel baits, crack-and-crevice treatments, and sanitation guidance for kitchens & food sites.
Cockroaches Native NZ
The primary “issue” is their occasional accidental entry into homes, often carried in on firewood or seeking shelter during extreme weather
Cockroaches Gisborne
Unlike some other species, Gisborne cockroaches are native to outdoor environments and do not spread disease, though they can still cause alarm.
Flies & Mosquitoes
Seasonal knock-down plus proofing and attractant management for homes & food premises.
Borer / Carpet Beetle / Silverfish
Timber and fabric pests treated with targeted residuals and preventive coatings.
Birds Proofing and Relocation
Bird proofing and relocation refers to a two-part approach for managing the presence of birds, typically in residential, commercial, or industrial settings.
Carpet Beetle
Carpet beetle larvae are the destructive stage, feeding on natural fibers like wool, silk, fur, leather, and felt.
Pantry Bugs
The larvae feed on the food, leaving behind physical contamination like webbing, faeces, and shed skins, rendering the food unfit for human consumption and leading to product waste
Eco Options
IPM plans, exclusion work, and reduced-risk products available on request.
Indian Meal Moth
The primary problem is that the larvae of the Indian meal moth feed on stored dry goods like flour, rice, cereal, nuts, and dried fruit.
Mediterranean Flour Moth
The Mediterranean flour moth is a significant pest of stored products worldwide.
