Australia’s Most Pest-Infested Suburbs Revealed – and Why Spring is the Season to Take Action

New data has revealed that Australia’s most pest-infested suburbs aren’t just in the bush or the tropics – they’re in some of our most affluent, built-up city areas.
According to a recent Airtasker report, analysing more than 30,000 pest control-related tasks posted between January 2020 and July 2025, eight of the nation’s top ten pest hotspots are located in Sydney.

From Bondi Beach to the Sydney CBD, these high-density regions are experiencing record levels of cockroach, spider, and rodent infestations – and experts say it’s a warning sign for the rest of the country as warmer weather kicks in. Contact Mr Pest Controller today for a Free No-Obligation quote

Sydney Tops the List of Pest Hotspots

The Airtasker findings show Sydney’s CBD, Eastern Suburbs, and Inner West lead the nation for pest activity.
The CBD recorded the highest number of pest-related jobs at 13%, followed by Marrickville and Surry Hills at 6%, and Bondi Beach at 11%.

These are some of the most sought-after and expensive postcodes in Australia, proving that pests don’t discriminate between high-rise apartments or multimillion-dollar homes.
Dense population, older housing, and plenty of food sources make these urban areas the perfect environment for pests to thrive.

But the findings also point to a broader trend – urban pest problems are increasing across all major Australian cities, especially along the eastern states.

Why the Problem Extends Beyond Sydney

While Sydney may have taken the top spot, similar pest patterns are emerging in Queensland, Victoria, and South Australia.
Brisbane and its surrounds were named the second most pest-affected area nationwide, with higher activity linked to humid conditions and population growth.
In Melbourne, rodents and fleas were reported as the most common culprits, while coastal and suburban regions in Adelaide have also seen a noticeable uptick in pest reports.

According to Airtasker’s data, pest control tasks typically spike by over 120% during the warmer months, especially between December and February – a clear reminder that prevention in spring is the smartest move for homeowners.

Why Spring is Prime Time for Pest Prevention

Spring creates the perfect environment for pests to breed, nest, and spread.
Warmer days and higher humidity trigger increased movement, while homes and gardens provide ample shelter and food.

Common Spring Pests in Australia

• Cockroaches: Thrive in humid kitchens, drains, and storage areas.

• Spiders: Nest in roof voids, garages, and outdoor furniture.

• Rodents: Seek food and nesting materials indoors as temperatures rise.

• Ants: Build colonies near moisture sources and invade kitchens for food.

• Termites: Begin new colonies as timber becomes warm and damp.

Once pests establish themselves, removal becomes harder and more costly.
That’s why licensed pest technicians recommend seasonal inspections and treatments during spring to prevent infestations before they begin.
