With economic instability, rising living costs, and increasing desperation in many areas, home burglaries are becoming more common than ever. The truth is, most break-ins don’t happen at random. They’re often the result of careful scouting by criminals who’ve already chosen their target – possibly your house.
The good news? Burglars tend to leave behind warning signs long before they strike. By learning how to recognize these red flags early, you can take action to protect your home, your property, and most importantly, your family. Below are ten major signs your house might be on a burglar’s radar.
1. Unfamiliar Cars Creeping Through the Neighborhood

If you’ve spotted a car driving unusually slow down your street, especially one you don’t recognize, it’s time to pay attention. Sure, it could be someone lost or even scoping out real estate. But it could also be someone casing homes for a potential break-in.
Burglars often do test runs before hitting a target. They drive through neighborhoods to observe routines, check for security cameras, and see which homes appear unoccupied. If a car seems out of place and lingers more than once, jot down details like the make, model, color, and even partial license plate. Share that information with neighbors and consider notifying local authorities if the behavior persists.
2. A Sudden Increase in Flyers, Door Hangers, or Business Cards

Getting the occasional pizza flyer is normal. But if you notice paper ads, business cards, or fake notices shoved into your door handle or mailbox repeatedly, and they stay there untouched for days, it could be more than marketing.
Burglars sometimes use this tactic to test whether a home is occupied. If the flyer hasn’t been moved for a day or two, that tells them no one’s home. The same goes for packages or newspapers piling up. If you’re going out of town, ask a neighbor to collect them for you – or invest in a temporary mail hold.
3. Strange Marks on Your Home or Property

Believe it or not, criminals have been known to use coded symbols to communicate with one another. These marks can appear as seemingly random chalk drawings, stickers, or scratches near doorways, mailboxes, or fences. They may signal anything from “easy target” to “aggressive dog on site.”
If you spot unusual symbols or marks, take a picture, remove them immediately, and alert your neighbors. It’s also a good idea to do a regular walkaround of your property to catch anything suspicious early.
4. Mysterious Individuals Taking Photos of Your House

People taking pictures of your home without a clear reason should raise a red flag. While it’s possible someone just likes your landscaping or architecture, it could also mean your home is being documented as a potential burglary target.
Don’t confront them aggressively, but don’t ignore them either. If it feels safe, politely ask what they’re doing. If they seem evasive or disappear quickly, make a note of their appearance, any nearby vehicle, and the time. Let your neighbors know, and consider contacting local police to file a report if the behavior continues.
5. Disturbed Trash or Missing Mail

It’s one thing if raccoons are digging through your garbage. It’s another if your trash looks rifled through but there’s no sign of animals. Identity thieves and burglars may go through your waste looking for personal information like bank statements, utility bills, or even receipts – anything that gives insight into your routines or financial status.
To protect yourself, always shred documents with personal details before throwing them away. Keep your bins in a secure location until pickup day, and check your mailbox daily to avoid accumulating mail that signals you’re away.
6. Your Dog Suddenly Missing or Unwell

This one is particularly disturbing, but it’s happened more often than you’d think. If your dog goes missing or falls sick unexpectedly, and you suspect foul play, it could be a sign someone is trying to remove your first line of defense.
Burglars know that a barking dog can scare them off or alert the homeowner. In extreme cases, they may try to poison or abduct a dog before returning later to commit the crime. If you ever suspect your pet was targeted, report it immediately. And consider adding cameras near your yard or dog’s usual areas.
7. Scratches or Damage Around Doors and Windows

Have you ever noticed strange scratch marks near your door lock or windows? They might not just be the result of wear and tear. These could be signs of a failed break-in attempt or someone testing how secure your locks are.
This kind of tampering is typically a precursor to a full-blown burglary. If you see these marks, don’t ignore them. Reinforce your doors and windows with high-security deadbolts, doorbell cameras, and window sensors. The sooner you act, the better.
8. A Broken Window With No Clear Cause

Coming home to a shattered window is unsettling, especially when there’s no ball, storm, or kid in sight. While it could be an accident, burglars sometimes intentionally break a small window to test whether anyone is home or if an alarm system will go off.
This tactic, sometimes called “probing,” helps them assess how much attention a property gets. If nothing happens after they break the glass, it might confirm the house is vulnerable. If you ever find broken glass for no clear reason, call the authorities, inspect the rest of your home, and double-check that your alarm system is functioning.
9. Tape Over the Door Lock

It might seem harmless – a little piece of tape stuck to your door lock. Maybe you think a delivery person left it, or a kid was being silly. But tape over a lock is a sneaky trick burglars use to see if anyone is coming and going.
If the tape is still there the next day, they assume the house is vacant. Always remove it immediately and let others on your street know. It’s a low-tech tactic, but don’t underestimate its usefulness to criminals.
10. Fuel Suddenly Missing From Your Car

If you walk out one morning and your gas tank is unexpectedly low, even though you’re sure you had more in there, it might not be just forgetfulness. Fuel siphoning is more than just theft; it’s often a test.
When someone steals gas from your vehicle in your driveway, it shows they’re comfortable enough approaching your home and might be checking how observant or reactive you are. If you don’t notice or take action, they may feel emboldened to return – this time to try your front door.
Stay One Step Ahead

Burglars are calculated. They’re watching your routines, testing your responses, and probing for weak spots. But once you know what signs to look for, you can flip the script – and become the one who’s prepared.
Install visible cameras. Talk with your neighbors. Lock your trash. Keep your yard well-lit. And most importantly, trust your instincts. If something feels off, it probably is.
Being aware of these 10 red flags doesn’t mean living in fear – it means living smart. Because in today’s world, home security isn’t a luxury. It’s a necessity.
