You keep a clean house. You vacuum, wipe down surfaces, take out the rubbish. But pests still find their way in. The reason? They’re nesting in places you rarely look at.
Most homeowners scrub the obvious areas while cockroaches and mice quietly set up camp in forgotten corners. By the time you spot them scurrying across the floor, they’ve already made themselves at home. Let’s talk about where these little invaders actually hide.
Behind Your Kitchen Appliances
Pull your fridge away from the wall. See all those crumbs? That grease buildup? The space behind there stays warm and dark, which cockroaches and mice absolutely love.
Your stove isn’t any better. Food splatters get underneath, creating a buffet. The dishwasher has moisture plus food scraps. Professional cockroach control always includes checking these spots first.
And that cabinet under the sink? Dark, often damp from leaky pipes. It’s like a five star hotel for silverfish and roaches.

Inside Your Walls
This one freaks people out. Your walls have hollow spaces running through them. Termites, rats, and cockroaches use these like secret tunnels to get around your house.
You hear scratching at night? Notice small holes appearing in your drywall? See mud tubes climbing your foundation? Something’s living in there. Getting a termite inspection done could save you thousands in repairs.
Possums and rats particularly love ceiling cavities. They shred your insulation for bedding and breed up there without you having a clue.
Basement Corners and Crawl Spaces
Basements tick every box for pests. Cool temperature, darkness, humidity, stuff that never moves. Spider’s web up the corners. Silverfish munch through cardboard boxes. Crickets set up residence.
Crawl spaces are even worse because nobody goes down there unless they absolutely have to. The soil underneath gives termites direct access. Bad ventilation means constant dampness.
Got spiders throughout your entire house? The main colony probably lives in your basement. That’s why spider control needs to target the source, not just the ones you see.
Bathroom Hiding Spots
What makes bathrooms attractive:
- Always moist from showers and sinks
- Warm and mostly undisturbed
- Organic gunk building up in the drains
- Gaps around plumbing that nobody seals properly
Silverfish eat the glue in wallpaper. They’ll even nibble your towels. Drain flies breed in the slime inside your pipes. And yes, cockroaches can climb up through your drains if the water trap dries out.
Check where your pipes go through the wall. Most homes have gaps there that should be sealed, but aren’t.
The Garage
Those cardboard boxes stacked against the wall? Rodents chew right through them. They love nesting in old blankets, holiday decorations, anything soft they can shred.
High risk garage items:
- Cardboard boxes with fabric inside
- Pet food in opened bags
- Woodpiles against walls
- Potting soil left open
That gap under your garage door? Gets bigger as the weather stripping wears out. Mice, snakes, and lizards slip right through.
Your Attic
Attics get baking hot in summer and freezing in winter. Doesn’t matter to rats and possums. They burrow into insulation, poop everywhere, and chew through electrical wiring.
Those boxes of Christmas decorations you store up there? Moths and silverfish are having a field day destroying your stuff while you’re downstairs living your life.
Roof rats got their name for a reason. They get in through damaged roof vents or tree branches touching your house. Once they’re in, they breed like crazy. That’s when you need professional rodent control to sort it out.
Behind Your Cabinets
Cabinet backs usually sit against exterior walls with gaps around the plumbing. Mice sprint behind your dinner plates. Cockroaches hang out near where you store your coffee mugs.
The space under your bottom cabinets collects crumbs and stays dark all day. Grab a torch and look under there. You might not like what you find.
Windows and Doors
Easy entry points:
- Worn out weather stripping
- Cracked window frames
- Screens with holes or gaps
- Door thresholds that don’t seal
Stink bugs and ladybugs squeeze through openings you can barely see. Dead bugs piling up on your window sill means there’s a gap somewhere letting them in.
Sliding glass doors are terrible for this. The tracks wear down and leave openings big enough for mice to waltz through.
Laundry Room
Behind your washer and dryer stays warm from the machines running. Lint builds up back there. It’s cosy, dark, and most people never clean it.
When did you last pull those machines out? Probably never, right?
Your laundry floor drain can dry out if you don’t use it much. Once that water trap evaporates, pests have a direct path from your sewer pipes into your house.
Outdoor Stuff
Plastic chairs stacked on the patio collect rainwater in the hollow legs. Perfect for mosquitoes to breed. Garden furniture cushions make great rodent nests. Your BBQ has grease and food scraps that attract everything.
Sheds and outdoor storage boxes become winter homes for pests. Wasps build nests under the roof overhang. Termites attack from the ground up if the shed’s made of wood.
Air Conditioning and Ducts
Your AC system moves air around your house. Unfortunately, it can also move pests. Cockroaches travel through vents. Dead rodents in ductwork smell absolutely awful.
The outdoor unit needs attention, too. Leaves pile up around it. Water pools underneath. Insects move right in.
Professional possum removal sometimes means checking your entire duct system because possums use them like a highway through your house.
Chimneys
Birds nest in chimneys you don’t use. Blocks the ventilation and becomes a fire hazard. Bats roost up there during summer. Raccoons and squirrels think chimneys make perfect homes.
Fireplaces that don’t get used much attract spiders and crickets. The damper might not close properly, leaving a gap straight to your roof.
Never stack firewood inside near your fireplace. It brings termites, carpenter ants, and spiders right into your home. Keep wood outside and only bring in what you’re burning that day
Under Your Deck
The space under your porch or deck is protected from the weather and predators can’t get to it easily. Skunks, opossums, and groundhogs love setting up there.
Smaller pests treat it like a base camp. They nest underneath, then look for ways into your actual house through your foundation.
What You Should Do
Pests win because they find the spots you ignore. They don’t need much. Just a crack to squeeze through, somewhere dark, and a bit of food now and then.
Check these hidden areas once a month. Takes less time than dealing with a full infestation later. Some problems need professional help to be solved.
