Winter Creepers: How to Keep Cockroaches and Spiders Out of Your Home
Just because you’re rugged up in your cosiest jumper doesn’t mean the pests have packed it in for the season. In fact, winter is prime time for some unwelcome houseguests. As the temperature drops, cockroaches and spiders start seeking refuge indoors, drawn to the same warmth and shelter you are.
The good news? There are simple steps you can take to keep your home pest-free during the colder months. At Pestline, our spider and cockroach pest removal solutions also help ensure that you don’t have to share your space with eight-legged lurkers or sneaky roaches.
Read on for expert tips to stop these winter creepers in their tracks, before they get too cosy.
Why Cockroaches and Spiders Come Indoors in Winter
Just because it’s cold outside doesn’t mean cockroaches disappear – they simply get smarter about where they hide. Being cold-blooded, they need warmth to survive, and your home offers plenty of it. Think warm, dark spots like behind the fridge, under the floorboards, or near leaking pipes- places that stay cosy and damp.
Now toss in a few crumbs, a pet food bowl, or a splash of water from the sink, and these pests aren’t just surviving winter; they’re thriving in it if they find the right spot. That’s why effective Melbourne winter pest prevention requires more than sealing doors or setting traps – it’s about understanding how and where pests settle in when we’re not looking. Fun fact: cockroaches can survive for a month without food, but only a week without water, so bathrooms and kitchens are high on their hit list.
Spiders operate differently. Some outdoor species go into a form of dormancy, but others actively relocate indoors to escape the elements. Certain common house spiders, like the daddy long-legs, prefer stable, dry environments and will happily take up residence in the nooks and crannies of your home. Others, like the black house spider, stay active indoors, gravitating toward undisturbed areas like roof voids, window frames, and garages.
Signs of Cockroach & Spider Infestations
Not sure if you’ve got signs of winter pest infestations? If you’re spotting pepper-like droppings in cupboards or corners, catching a whiff of a musty smell that doesn’t quite belong, or noticing shed skins (yep, they shed their skin like tiny, crunchy snakes), chances are you’ve got roaches on the move.
Spiders tend to be a bit more subtle, but as one of the most common Australian household pests, they still leave clues. Webs in window frames, dusty corners, or between boxes in the garage are obvious giveaways. And if you come across small, white egg sacs (especially tucked away in quiet spots) they’re probably planning a family. Bottom line? If something feels off or the corners seem a little too webby, it might be time to investigate further.
Top Winter Pest Prevention Tips
Seal Entry Points
Examine window frames and door seals for gaps because pests will enter through any openings where daylight is visible. Place weather stripping or door sweeps in areas where pests move through gaps. To prevent moisture buildup, apply silicone caulk to fix cracks in skirting boards and wall edges as well as tiled surfaces in kitchens and bathrooms.
Mesh screens on your vents will block pests from entering, but allow air circulation in your home. Use steel wool or expanding foam to fill gaps under sinks where pipes go so that roaches and spiders can’t establish their nests there.
Declutter & Deep Clean
Decluttering is your first line of defence. Piles of newspapers, old cardboard boxes, and crowded corners create the perfect hideouts – dark, still, and undisturbed. For how to get rid of German cockroaches, start by tackling clutter, as it traps warmth and gives them cover to scurry freely, creating ideal hiding spots for these pests.
Once you’ve cleared the decks, a deep clean helps remove any crumbs, spills, grease, or other food sources that might tempt cockroaches to stick around. Vacuum behind appliances, wipe down kitchen surfaces (especially under the toaster!), and don’t forget those forgotten corners where spiders love to spin a sneaky web.
Fix Leaks & Manage Moisture
Begin by repairing all possible leak sources including dripping faucets and leaking pipes, along with toilets that run without stopping. Inspect under sinks and around appliances, together with basement areas for moisture indications. To prevent moisture accumulation in basements and bathrooms, maintain dry air by operating a dehumidifier. Make sure to dry any water buildup after showering and avoid leaving standing water in sinks or trays.
Eliminating their access to water will make your home much less appealing to these thirsty pests.
Natural Repellents
Cockroaches and spiders absolutely hate the smell of peppermint. Simply mix a few drops with water in a spray bottle, and you’ve got yourself a potent pest-repellent mist that also makes your house smell like a refreshing peppermint garden.
Citrus is another great one. Both cockroaches and spiders dislike the strong scent of citrus, so don’t hesitate to squeeze lemon or orange juice into your cleaning solution. You can also mix up a citrus spray with a little water and vinegar to create a double-threat of freshness and pest control.
Speaking of vinegar, this kitchen staple is also a mighty weapon in your pest-fighting arsenal. Cockroaches aren’t fans of its acidic nature, so a vinegar-water spray can help deter them from hanging out in your cupboards or corners. So, if you want to ditch the chemicals and embrace natural repellents, these simple ingredients will give your home a pleasant scent and a pest-free vibe!
Outdoor Maintenance
If you’re serious about keeping pests at bay, regular outdoor maintenance should be part of your yearly Australian pest management calendar. Shrubs that have grown too tall alongside grass that stands too high and vines that have become tangled create convenient paths which allow pests to reach your home directly. Those plants create perfect hiding places for cockroaches who need shelter. Maintaining trimmed vegetation reduces entry points and pushes pests to search for homes elsewhere.
Take time to remove debris such as fallen leaves, branches and wood piles that accumulate around your foundation. These accumulations create perfect hiding places for various spiders, which become more noticeable when temperatures drop. Your property needs a basic “border patrol” to keep creepy crawlies from settling near your home.
When to Call a Winter Pest Control Professional?
Even when you’ve done everything right – cleaned the house top to bottom, sealed every gap you can find, maybe even tried a few natural remedies – spiders and cockroaches can still find a way in. And that’s the frustrating part. They’re good at hiding, and some infestations are just too deep or stubborn for DIY methods to fully handle.

FAQs
Do cockroaches go away in winter?
No. Cockroaches are cold-blooded and need warmth, so in winter they move to the warmest, darkest spots in your home. These include behind the fridge, under floorboards and near leaking pipes. If they find food, water and warmth, they can thrive indoors all season.
Why do cockroaches and spiders come inside in winter?
Both are looking for warmth and shelter as temperatures drop. Cockroaches are drawn to warm, damp spots with crumbs, pet food and water. Some spiders relocate indoors to escape the weather, and others stay active in quiet, undisturbed areas.
How long can cockroaches survive without food or water?
Cockroaches can survive about a month without food, but only about a week without water. That’s why kitchens and bathrooms are their favourite spots. Fixing leaks and drying up standing water makes your home much less appealing to them.
What are the signs of a cockroach infestation?
Look for pepper-like droppings in cupboards and corners, a musty smell that doesn’t belong, and shed skins. Seeing cockroaches in the open in daylight can also mean the infestation is well established.
Which spiders come inside in winter?
Two common ones are daddy long-legs spiders and black house spiders. Daddy long-legs prefer stable, dry spots and settle into nooks and crannies. Black house spiders stay active indoors and favour undisturbed areas like roof voids, window frames and garages. Webs and small white egg sacs are the main signs.
How do I keep cockroaches and spiders out of my home in winter?
Four things make the biggest difference:
- Seal gaps around windows, doors, vents and pipes.
- Declutter and deep clean to remove hiding places and food sources.
- Fix leaks and reduce moisture.
- Trim vegetation and clear leaves, branches and wood piles away from the house.
Do natural repellents like peppermint, citrus and vinegar work?
They can help deter cockroaches and spiders. A peppermint oil and water spray, a citrus spray, or a vinegar-and-water spray can discourage pests from lingering in cupboards and corners. They won’t remove an established infestation or its source. If you’re still seeing pests after doing everything right, call a professional.
When should I call a pest controller for winter cockroaches or spiders?
Call when you keep seeing pests despite cleaning, sealing gaps and trying DIY methods. Pestline’s winter cockroach treatments track down the source and target the hidden areas where cockroaches nest and breed. The spider treatments flush spiders out of hiding, remove webs and create a barrier to keep them away. Call 1300 361 646 or request a quote.
Do cockroaches bite?
Rarely. Cockroaches can bite, but it’s uncommon. The bigger concern is the bacteria they spread across food and surfaces as they move around. Cleaning up food and water sources reduces their access to both.
