If you think pest control is just for the warmer months, you’re not alone—but it’s a common misconception. While pests like ants and flies are more visible in summer, winter in Adelaide brings its own set of pest problems.
So, do you need a pest spray in winter?
In short: yes—and here’s why.

What Happens to Pests in Winter?
Many people assume pests simply disappear in winter. But in reality, they’re just hiding—often inside your home.
In Adelaide, cooler temperatures send pests looking for shelter, warmth, and food. Your roof cavity, walls, cupboards, and even your pantry offer ideal hiding spots.
Winter pest activity you may not see includes:

Winter pest activity you may not see includes:
- Cockroaches nesting in kitchens and wall cavities
- Rodents (rats and mice) moving into ceilings and garages
- Spiders retreating indoors to stay warm
- Silverfish hiding in damp bathrooms or laundries
Why Winter Pest Control Is Just As Important
Here’s why skipping your winter spray can backfire:
1. Pests breed quietly during winter
Many pests slow down, but they don’t stop breeding. Rodents can have litters every few weeks—even in cold weather.
2. Early treatment = fewer problems later
By treating during winter, you stop infestations before they explode in spring. You’re not just killing visible pests—you’re breaking the breeding cycle.
3. Your home is more sealed up in winter
Windows stay shut and heating’s on. That means pest sprays stay effective longer, and pests can’t escape once treated.
4. Rodents cause winter-specific damage
In colder months, rats and mice chew insulation, wires, and even pipework while trying to stay warm—leading to electrical fires or water damage.

Winter Sprays Work Best When Pests Are Hidden
 | This may seem counterintuitive—but it’s actually the perfect time to spray. Pests are hiding in key locations (wall cavities, behind fridges, roof voids), and a professional treatment can hit those zones before pests emerge in spring. An experienced pest control technician knows where pests overwinter—and targets those exact spots. |
