Winter pests are sneaky and often go unnoticed—until it’s too late. Here’s what’s hiding in your home and how to stop them before they spread.
Most homeowners associate pest problems with the warmer months, but winter has its own cast of unwanted intruders. As temperatures drop, all kinds of winter pests start seeking warmth, shelter, and food—and your home ticks all the boxes.
What makes winter pests especially tricky is how quietly they move in. You often don’t realise they’re around until they’ve already made themselves at home. Below, we cover the most common culprits and the subtle signs they leave behind.
If any of this sounds familiar, it may be time to bring in pest control support from a professional listed on ServiceSeeking.com.au. It’s one of the simplest ways to stay on top of infestations before they become costly problems.
1. Rodents (Mice & Rats)
Winter is peak season for mice and rats in Australia. These warm-blooded animals are on the hunt for cosy spots—wall cavities, sheds, basements, even pantries.
What you might notice:
- Scratching noises in the ceiling or walls at night
- Droppings in cupboards or behind appliances
- Chewed packaging or wiring
Rodents can spread diseases, trigger allergies, and damage electrical systems. They’re rarely alone—if you spot one, there are likely more. Professional pest control can detect and address infestations before things escalate.
2. Ants
Ants slow down in cold weather, but they don’t vanish. Some species continue to be active indoors where it’s warm, especially if there’s a food source nearby.
What you might notice:
- Trails along skirting boards or kitchen benches
- Small piles of soil or debris near walls
- Nesting near stored items or timber piles
These tiny intruders can contaminate food, spread bacteria, and bite. If ants are active during winter, your home may be providing ideal nesting conditions.

3. Termites
Termites don’t take a season off. While they might burrow deeper underground during colder months, they remain active—especially if they’ve already made their way into your home.
What you might notice:
- Hollow-sounding timber or sagging floors
- Cracks in walls or ceilings
- Mud tubes near foundations
They’re hard to detect without trained eyes, and the damage they cause can be expensive. Scheduling regular termite inspections, even during winter, is highly recommended.
4. Bed Bugs
Though more associated with travel than seasons, winter can still bring bed bug problems indoors. As people spend more time under blankets or bring home luggage and second-hand items, these pests can spread unnoticed.
What you might notice:
- Small, itchy bites—especially in a straight line
- Tiny blood spots or black dots on bedding
- An unexplained musty odour
They hide in mattress seams, bed frames, and soft furnishings. Bed bugs don’t transmit disease, but can quickly make your sleep a nightmare.
5. Cockroaches
They might love the heat, but cockroaches are also known for thriving indoors during winter. Your kitchen, laundry, or bathroom could be offering warmth and easy access to food scraps.
What you might notice:
- Droppings that resemble ground pepper
- Oily smells in dark corners
- Roaches scurrying away when lights flick on
Aside from being unsettling, roaches are known carriers of germs and bacteria. If you’re spotting them during winter, there may already be a colony inside.

6. Overwintering Pests (Stink Bugs, Beetles, Ladybirds)
Overwintering pests sneak into your home during autumn and hunker down for the cold season. By winter, they’re tucked into wall cavities, window frames, and roof spaces.
What you might notice:
- Clusters of insects around windows or light fixtures
- Popping sounds when lights are turned on
- Bad odours from disturbed bugs
They may seem harmless, but large numbers can cause stains, smells, and general discomfort indoors.
7. Mosquitoes and Flies
You might think mozzies disappear in winter—but in some parts of Australia, especially where it stays mild, they’re still a problem.
What you might notice:
- Buzzing at dusk or dawn
- Bites, especially on ankles and exposed skin
- Increased activity near still water (like garden pots or birdbaths)
While flies are mostly a warm-weather issue, mosquitoes can still thrive indoors if they’ve found somewhere to breed.
Why Winter Pest Control Still Matters
Winter pests are experts at hiding. Most homeowners don’t realise there’s a problem until they’ve already caused damage, spread disease, or become a full-blown infestation.
That’s why it’s worth booking a pest control inspection even in the cooler months. A qualified professional can:
- Identify subtle signs you may have missed
- Use targeted treatments that are safe and effective
- Recommend prevention strategies to protect your home year-round
