Pests in Queensland

Queensland’s warm climate means a long pest season across most of the state. From subtropical South East Queensland to the tropical north, cockroaches, ants, mosquitoes, spiders, rodents and termites are part of everyday home maintenance.

Updated 20 September 2026 · General information about local pest conditions.

Queensland climate and pest activity

  • South East Queensland (including Brisbane, the Gold Coast and Sunshine Coast) is humid subtropical: hot, wet summers and mild, drier winters.
  • North Queensland is tropical with a distinct wet season, supporting year-round insect activity.
  • Inland Queensland is hotter and drier, with pest activity tied closely to rain events.

Housing and local environment

  • Raised timber Queenslanders and post-war homes in older suburbs.
  • Brick-veneer and slab-on-ground homes in newer estates.
  • Growing apartment density in inner Brisbane and coastal centres.
