Most people expect pests to become more active during warmer months, so it often catches homeowners off guard when they suddenly start hearing scratching in the roof or spotting droppings in winter.
On the Gold Coast, winter is actually one of the busiest times for rodent activity indoors.
As temperatures cool down, rats and mice start looking for the same things we do. Warmth, shelter and easy access to food. Your roof void, garage, pantry or even your car can quickly become an attractive place to settle in.
For many families, the first sign of a problem is hearing movement in the ceiling late at night. Others notice chewed packaging in the pantry or an unusual smell in the garage. By the time rodents are regularly being seen, there is often already a nest nearby.
Why Rodents Move Inside During Winter
Even though Gold Coast winters are fairly mild, rodents are still looking for warmer places to shelter.
Roof voids are one of the most common nesting spots because they are dry, protected and usually undisturbed. Garages, sheds and storage areas also become popular hiding places, especially if there are cardboard boxes, pet food or clutter providing cover.
Homes near bushland, waterways or construction areas can sometimes notice increased activity as rodents are pushed into surrounding neighbourhoods.
What surprises many people is how little space rodents need to get inside.
Mice can squeeze through gaps not much bigger than a 5-cent coin and rats only need slightly larger entry points. Small openings around roof tiles, garage doors, plumbing or air conditioning lines are often enough.
Once they are in, they tend to stay close to food and warmth.
The Signs People Often Miss
Rodents are good at staying hidden, especially early on.
The obvious signs are usually droppings, scratching sounds or visible damage, but there are often smaller clues beforehand.
A musty or unusual smell in certain parts of the home can sometimes point to nesting activity. Greasy marks near skirting boards or walls can happen when rodents repeatedly travel the same paths. Pet food disappearing quickly or unusual pet behaviour around walls and cupboards can also be worth paying attention to.
We also regularly hear from people who suspect rodents after finding damage in their cars.
During winter, engines stay warm after driving, which makes them surprisingly attractive hiding places. Rodents can nest under bonnets, chew through insulation and even damage wiring. Modern vehicles have so many electrical components that even minor damage can become expensive very quickly.
If dashboard lights suddenly appear or something does not feel right while driving, it is worth getting things checked.
Why DIY Rodent Control Often Falls Short
Most homeowners try something themselves first, which makes sense.
Baits from hardware stores or supermarket traps can help in some situations, but they rarely address the bigger issue of how rodents got in and where activity is actually happening.
One of the biggest challenges with rodents is that what you see is usually only part of the problem.
You might notice one mouse in the kitchen, but nesting could already be happening in the roof. Or bait may seem to work for a week or two, only for activity to return because entry points around the home have not been addressed.
Winter rodent issues often need a broader approach that looks at the whole property rather than treating one room.
Changes to Rodent Control in Australia
Since 24 March 2026, new regulations have changed how certain rodent baits are to be used across Australia.
The updates mainly affected second-generation rodenticides, with a stronger focus on protecting pets, wildlife and the environment while still allowing effective rodent control.
For homeowners and businesses, this means rodent treatments may look a little different moving forward. Outdoor baiting faces tighter restrictions, with tamper-resistant and weather-resistant bait stations becoming the standard. Bait stations also need to be secured properly and positioned close to buildings rather than along fence lines or in burrows.
There are now also limits around ongoing bait use, meaning treatments may need to be reviewed more regularly to ensure they remain safe, effective and compliant.
In some situations, alternative products such as first-generation rodenticides may be recommended. These products generally require rodents to feed more than once but can still be highly effective when used correctly.
At LessPest, we are continuing to adapt our treatment plans to meet the latest requirements while keeping homes, businesses and families across the Gold Coast protected with safe and practical rodent solutions.
What Helps Reduce Rodent Activity Around the Home
While no home is completely rodent-proof, there are practical ways to make your property less attractive.
Keeping food sealed, reducing clutter in garages, cleaning pet bowls after feeding and checking roof spaces for signs of activity can all help.
If there is warmth, shelter and easy food nearby, chances are they will find it eventually. The earlier activity is picked up, the easier it usually is to manage.
Don’t Let a Small Rodent Problem Become a Bigger One
Rodent activity tends to increase during winter and what starts as a bit of scratching in the roof or a few droppings in the garage can quickly turn into a much bigger issue if left too long. The good news is that early action usually makes things much easier to manage.
At LessPest More Control, we help families across the Gold Coast take the stress out of rodent problems with practical solutions that are safe, effective and tailored to the home.
