Why am I getting rats and mice in my Sydney home?
TL;DR — Quick Answer
Rodents enter Sydney homes because they are searching for food, water and shelter. Rats and mice can hide in roofs, walls and cupboards, causing contamination and property damage. Effective rodent control combines inspection, treatment and prevention methods to keep homes and businesses protected.
It starts with a frantic call: “The rat is sitting behind the chair! Come catch it right now!”
Many people expect instant removal, but rodents are far smarter and more agile than most realise.

How smart are rats and mice really?
Rats and mice are highly intelligent, which is why they’re used in behavioural research. A study by Ben Vermaercke and colleagues at KU Leuven, published in Harvard Business Review Jan–Feb 2015, found rats can solve complex problems faster than humans in some controlled tests.
They learn quickly, remember safe paths for up to 18 months, and avoid unfamiliar objects — which is why new traps often stay untouched for days.
According to NSW Health, rodents can detect poison in low doses and will avoid it if alternative food is available.
How do rodents get inside my property?
They only need tiny gaps to enter:
- Holes as small as 10mm for mice, 20mm for rats
- Spaces around pipes, cables and vents
- Damaged weatherboards, roof gaps and under doors
- Garages, subfloors and roof cavities are common entry points in Sydney homes
Pest Control Australia data shows over 60% of infestations start through gaps people don’t even notice.
Why do they stay once they get in?
Three simple things keep them coming back:
- Food: Unsealed bins, pet food left out, crumbs and compost
- Water: Leaking taps, condensation, pet bowls or uncovered drains
- Shelter: Clutter, garden beds against walls, stored items and warm cavities
Food Standards Australia New Zealand notes rodents spread over 35 diseases including salmonella and leptospirosis, contaminating food preparation areas rapidly.

Frequently Asked Questions
Can you remove a rat immediately when you arrive?
We can’t guarantee instant catch — they’re too fast and wary. But we can locate nesting spots, block entry and start effective treatment straight away.
How quickly do rodents breed?
A single pair can produce up to 80 offspring a year, so delays make the problem much harder to control.
Are rodent treatments safe for kids and pets?
Yes — we use approved products and place them out of reach, following all NSW safety regulations.
Do you offer a guarantee?
Yes — we include a 3 month warranty and return for free if pests reappear within that period.
