A couple of small changes can make a big difference when it comes to home security. Even little things that seem normal to you, like leaving a door unlocked or keeping valuables visible, can make your home more appealing to thieves. Here’s a deep dive into 15 common mistakes that invite thieves in—and tips on how to fix each one.
Leaving Doors Unlocked

A lot of break-ins happen just because someone forgot to lock up. Even if you’re just popping out for a few minutes, leaving your door unlocked is practically rolling out the welcome mat. Make it a habit to check all doors—including back and side ones—whenever you head out or call it a night. If you tend to forget, a smart lock that auto-locks after a bit can be a real lifesaver.
Hiding Spare Keys in Obvious Places

Hiding a spare key under the mat, in a plant pot, or inside a fake rock may seem safe, but these spots are the first places thieves look. If you must have a spare key outside, buy a small lockbox with a code. Or, consider leaving it with a trusted neighbor who can give you access if you’re locked out.
Posting Vacation Photos While You’re Away

Sharing travel photos while you’re still on vacation lets thieves know your home is totally empty, giving them plenty of time to plan a break-in. Instead, try posting your vacation memories once you’re back so you’re not telling anyone that you’re away. While you’re gone, leave a few lights on timers to make it look like someone’s home.
Leaving Valuables Visible from Windows

If you can see expensive electronics, jewelry, or even your car keys from the outside, thieves can, too. Arrange your rooms in a way that all these high-value items aren’t visible through windows. Try closing your blinds or curtains at night, or consider frosted window film for a little privacy without losing natural light.
Having No Exterior Lighting

Thieves love dark homes because it gives them cover to sneak around. Installing motion-sensor lights by entry points or keeping porch lights on all night can stop thieves as they will make them feel exposed. Pay special attention to any dark areas around the side or back doors, where thieves are more likely to try and enter unseen.
Advertising New Purchases

Setting out the box from a new TV or gaming console with your trash practically advertises what’s inside your home. Instead, break down boxes and place them inside trash bags or recycling bins. This way, you’re not showing thieves that you just got something pricey. And don’t take this lightly because items like TV or your computer have a high resale value.
Not Locking Windows

Unlocked windows, especially the first-floor ones, are easy targets for thieves. Even if you’re only stepping out for a few minutes, make sure every window is locked. For extra security, try adding window locks or safety bars. If you’ve got sliding windows, drop a dowel or bar in the track to keep them from being forced open.
Keeping a Predictable Schedule

If you always leave for work at eight and come back at five, thieves will quickly pick up on your routine, and they’ll figure out exactly when the house is empty. Try to vary your schedule if possible, or at least use light timers and smart devices to turn lights, TVs, or radios on and off at random times so it appears someone’s home even if you’re not.
Not Installing a Security System

Homes without a visible security system are far more attractive to thieves. Even a basic system with door and window sensors can act as a deterrent. Many modern systems are affordable and very easy to set up yourself. Adding a visible camera or “Protected by” security sign can also discourage anyone thinking about breaking in.
Leaving Tools Outside

Tools like hammers, shovels, or even ladders left outside can be used to break into your home. Thieves can use these items to pry open windows, break locks, or gain entry to higher entry points. Maybe they can even steal these tools and ladders. Anything is possible when it comes to burglary. Always store your tools in a locked shed or garage.
Having Overgrown Trees or Bushes Near the House

Overgrown landscaping around windows and doors can create amazing hiding spots for thieves. Trim shrubs and bushes near entry points to remove potential cover, and consider planting thorny bushes beneath windows to make it even harder to hide. Good landscaping can help keep your home more visible and make thieves think twice before coming to steal from you.
Ignoring Broken Locks or Doors

A broken lock or door that doesn’t latch properly is an open invitation to literally any kind of criminal. Thieves notice these weaknesses almost immediately, and they can easily take advantage of your carelessness. Fix any broken or loose locks instantly, and consider backing doors with deadbolts or stronger strike plates for an extra layer of security.
Forgetting to Lock the Garage Door

A lot of people forget to lock the door between the garage and the house, thinking the main garage door is enough. But thieves can often get in through the garage and then find that door wide open. Always lock both doors and consider adding a garage door sensor that’ll alert you if it’s left open too long.
Leaving Mail or Packages Uncollected

A stuffed mailbox or a pile of packages by the door screams that no one’s home, which is exactly what thieves look for in an easy target. If you’re going away, ask a neighbor to grab your mail or put it on hold with the post office. For packages, try using an Amazon Locker or have them delivered to a secure pickup spot instead.
Posting Your Address on Social Media

Whether it’s in a “for sale” post, a job listing, or a location tag, revealing your address online is super risky. Burglars can use this kind of information to plan a break-in and even track your routines if you post regularly. Double-check privacy settings on your social media accounts and avoid sharing your exact address publicly. Use privacy features like “friends only” for location-based posts.
