Wellington Common Pests
Wellington's cold winters push rodents indoors — rat and mouse infestations are common in autumn and winter. The city's older villa stock has plenty of entry points for rodents. Wasp nests are common in Wellington's bush suburbs.
Rodents (Rats and Mice)
The most common pest call-out in Wellington. Signs: droppings, gnaw marks, scratching sounds in walls/ceiling, pet food disappearing. Treatment: baiting stations inside and outside the property. Follow-up visit typically required.
Cockroaches
German cockroaches (small, prefer kitchens/bathrooms) and American cockroaches (large, prefer warm damp areas). Treatment: gel bait plus residual spray. Multiple visits often needed to break the egg cycle.
Borer (Wood-Boring Beetle)
Common in NZ timber homes — especially older rimu and macrocarpa. Signs: small round holes in timber, powdery frass (sawdust). Treatment: surface spray penetrates and kills larvae. Best done in summer when larvae are active near the surface.
Wasps
NZ German wasps are aggressive and the nests get very large by summer. Nest removal involves chemical treatment at night (when wasps are inactive). Do not attempt DIY wasp nest removal on large nests.
NZ Pest Control Licensing
Pest controllers applying restricted pesticides must hold a GROWSAFE certificate or equivalent. Always ask for proof of certification before allowing pesticide treatment in your home.
