We all want to feel safe in our homes, but sometimes the things we do out of convenience, routine or forgetfulness can quietly make us more vulnerable. Whether you’re living in a freestanding house or a cosy apartment, these common habits could be inviting trouble in ways you might not expect. Here are seven behaviours that could be putting your home’s security at risk (and what to do instead):

Leaving windows unlocked (even “just for a bit”)

It’s tempting to leave a window cracked open while you pop out for coffee or leave a bedroom window ajar on a warm night. According to a survey by ADT, 67.85% of Brits have left their window open when out of the house. But open or unlocked windows are one of the most common entry points for intruders.
Even small windows can be accessed if someone’s determined, and you might not even realise one was left unlatched. Instead, get into the habit of checking all windows before leaving or going to bed. And that doesn’t have to mean no fresh air! Install window locks or restrictors if you like to keep them slightly open.
Posting your travel plans on social media
We’ve all seen it: a countdown to Bali, an airport selfie, or a “finally on our way!” post. The problem? You may be tipping off potential intruders that your house is unattended. Even if your account is private, social media oversharing can still increase your risk.
Instead, save the holiday spam for after you’re back. Post your travel photos once you’re safely home, when you can enjoy showing your friends and family your adventures stress-free once you’re back to real life.
Hiding a spare key outside

Still hiding your spare key under a pot plant? You’re not alone! According to the Australian home insurance comparison website Compare the Market, a sizable 36% of Aussies admit to stashing a spare key outside their home.
While it may feel like a harmless backup, it can also be one of the first things burglars check for. Instead of popping your key under the mat, invest in a secure lock box with a combination code, or leave a key with someone you trust.
Skipping outdoor lighting

A poorly lit exterior is basically an open invitation. Shadows and dark corners give intruders the cover they need to lurk unnoticed. Whether it’s your front entry, side path or backyard, darkness helps criminals stay out of sight.
To counter this, install motion-sensor lights or smart lighting systems around the perimeter of your home. These lights will automatically turn on when someone approaches, making it much harder for an intruder to sneak up undetected.
Neglecting your front yard

An overgrown lawn or uncollected mail can signal that nobody’s home, and sometimes that’s all it takes. Even if you’re just away for a weekend, a neglected exterior can attract unwanted attention. Instead of leaving your home untouched, ask a neighbour to bring in your mail and bins while you’re away, and consider hiring a lawn service for longer trips.
Leaving valuables in plain sight

Leaving expensive items like laptops, handbags, or even car keys within view of windows can make your home a more tempting target. A quick glance through a window is all a thief needs to deduce your home should be a target. Instead of giving the street an easy view of your possessions, close blinds or curtains when you’re not home and keep valuable items out of sight.
Forgetting to lock the back door

You might lock your front door religiously, but what about the side gate? Or the laundry door? Secondary entry points are often overlooked, and thieves know it. It only takes a few seconds for someone to enter through an unlocked door. To counter this, check all doors and windows as part of your daily routine. Consider upgrading older locks or installing a security system for added peace of mind.
It’s easy to fall into patterns that seem harmless, but small oversights can add up to big vulnerabilities. By swapping out risky habits for simple precautions, you’ll help keep your home safer and give yourself peace of mind every time you step out the door.
