Most break-ins are not random. Burglars tend to target homes that look unoccupied, and they read a handful of reliable signals before they ever try a door. The frustrating part is that most of those signals come from the homeowner, not some failure of the house itself.
Before your next trip, run through this list. Each item covers what people commonly do, why it catches the wrong kind of attention, and what you can do instead.
1. Posting Trip Photos and Check-Ins on Social Media While You Are Away
Sharing a sunset photo from your vacation destination feels harmless. But if your social media profiles are public, or if your friend list includes people you barely know, you have just announced to anyone watching that your home is sitting empty right now.
Burglars have adapted to social media. A post tagged at a resort three states away, timestamped today, tells a would-be thief exactly when the coast is clear. Even posts shared in private groups can spread beyond your intended audience through screenshots or mutual connections.
What to do instead: Save the travel photos and post them after you are home. Before your next trip, spend ten minutes auditing your privacy settings on Facebook, Instagram and any other platforms you use. Set your posts to friends only at minimum, and consider trimming your friend or follower list to people you actually know. Your vacation memories will look just as good posted a week later.
2. Letting Mail, Newspapers and Packages Stack Up
A mailbox stuffed with envelopes and a porch covered in packages is one of the oldest and clearest signs that nobody is home. A few days of accumulation is enough to attract attention on a typical residential street.
The fix here is easier than most people realize, and most of it is free. The United States Postal Service offers a free mail hold service (called “Hold Mail”) through USPS.com that pauses delivery for up to 30 days. USPS also offers a free service called Informed Delivery that sends you a daily email preview of your incoming mail and packages, so you know what is building up even if someone else is collecting it for you.
What to do instead: Schedule a mail hold through USPS.com before you leave. Contact your newspaper delivery service and pause delivery. For packages, delay shipments until after you return or reroute them to a neighbor, an Amazon locker or another secure pickup point. Ask a trusted neighbor to sweep your porch daily for any items that still arrive. That neighbor visit also adds visible activity around your home, which matters for the next few items on this list.
It is also worth calling your local police department’s non-emergency line before a long trip. Many departments offer a free vacation house-check program where officers on patrol will stop by your address periodically. Ask when you call whether that service is available in your area.
3. A House That Is Completely Dark Every Night, or One Where the Same Lights Stay On for Days
Both extremes give the same thing away. A home that goes pitch-dark every night the moment you leave is obviously unoccupied. But a home where the same living room lamp has been burning continuously for five days is almost as telling. Anyone paying attention notices that the pattern never changes.

Genuine occupancy looks varied. Lights go on and off in different rooms at different times. The kitchen light might come on early, the bedroom light later, the living room light sometime in the middle of the evening.
What to do instead: Smart plugs with scheduling features cost between $10 and $25 each at most hardware stores and are available from many online retailers. Plug a lamp into one, download the companion app, and set it to turn on and off on a schedule that mimics how you actually live. Use two or three plugs in different rooms on different schedules so the house looks actively occupied from the outside. Basic plug-in light timers without any smart features are even cheaper and work the same way. Set them before you leave and your house will continue to look lived-in every night you are gone.
4. An Unkept Yard, Unshoveled Snow and an Empty Driveway
Grass that has not been mowed in ten days, a sidewalk buried under uncleared snow, or a driveway that sits empty around the clock all point to the same conclusion: the residents are gone.
In winter especially, fresh snow that sits untouched on a driveway and walkway for more than a day or two is a visible flag to anyone driving through the neighborhood. In summer, a lawn that has gotten noticeably shaggy compared to neighboring yards tells the same story.
What to do instead: Arrange for lawn care before you leave. That might mean scheduling your usual lawn service for a visit mid-trip, asking a neighbor’s teenager to mow once, or setting up a temporary arrangement with a local landscaping company. For winter trips, line up a neighbor or a snow removal service to clear your driveway and walkway within a day of any significant snowfall.
On the driveway itself, ask a trusted neighbor whether they would be willing to park one of their cars there occasionally while you are away. A car in the driveway is one of the strongest visual signals that someone is home.
5. A Spare Key Under the Mat, in a Fake Rock or in a Garage Remote Left in an Unlocked Car
Hiding a spare key under a doormat or inside a fake rock is so common that it is practically a standard first stop for anyone trying to get into a home. Burglars know where to look. The mat, the fake rock, the planter by the front door, the top of the door frame: these spots are checked first precisely because so many people use them.
The garage remote left in a car parked in the driveway is a version of the same problem, and sometimes a worse one. If someone breaks a car window or your car is left unlocked, a garage remote gives immediate access to the garage and, from there, often to the house itself. Many people do not think to lock the interior door between the garage and the living area, which means the remote can be a direct path inside.
What to do instead: Remove any hidden spare keys from outside your home before you leave. If you need a key available for emergencies, give a copy to a trusted neighbor or use a lockbox secured to a fixed surface with a combination code. These are available at hardware stores for around $20 to $40 and are far more secure than a fake rock.

Take your garage remote inside with you or store it somewhere it cannot be reached from outside the car. Before your trip, make a point of locking the door between your garage and the interior of your house, and confirm that lock is in working order. If your garage has a side door, lock that too.
6. Announcing Your Absence Through Voicemail, Email Auto-Replies and Smart Devices
A voicemail greeting that says “We are on vacation until the 15th, leave a message” is a direct announcement of your absence to anyone who calls, including wrong numbers, telemarketers and anyone who looked up your number specifically to case your home. An email auto-reply that says “I am out of the office on personal travel until next week” gives the same information to every sender, including anyone who emails you by accident or specifically to check whether you are home.
Smart doorbells and cameras add another layer that many people overlook. Some doorbell apps let you set an away message for visitors, which tells anyone at the door that nobody is home. And a doorbell camera without alerts turned on can record a stranger at your door without telling you until it is too late.
What to do instead: Keep your voicemail and email auto-reply messages vague. Something like “I am away from the phone, please leave a message” or “I will respond to emails within a few days” tells callers nothing about your location or return date. Never mention travel or vacation in any automated message.
On your video doorbell and any outdoor security cameras, confirm that motion alerts are turned on and being sent to your phone. That way, if someone approaches your door, you see it in real time. Check the app before you leave to make sure notifications are active and the camera view covers the area you want monitored.
Also let a trusted neighbor know your return date and a good number to reach you. A neighbor who knows you are away is far more likely to notice and report something out of place than one who has no idea you are gone.
Quick Reference: Before You Leave for Any Trip
- Social media: Set profiles to friends only, hold vacation posts until you are home.
- Mail and deliveries: Schedule a USPS mail hold, pause newspaper delivery, delay or reroute packages, ask a neighbor to check your porch.
- Lights: Set smart plugs or timers in two or three rooms on different, varied schedules.
- Yard and driveway: Arrange mowing or snow removal in advance, ask a neighbor to park in your driveway occasionally.
- Keys and garage: Remove all hidden spare keys, use a lockbox or give a copy to a trusted neighbor, bring the garage remote inside, lock the garage-to-house door.
- Voicemail, email and devices: Keep automated messages vague, enable real-time alerts on your doorbell camera and outdoor cameras.
- Neighbor and police: Tell a trusted neighbor your return date, call the non-emergency line to ask about vacation house-check programs in your area.
Most of these steps take under an hour total. Set a recurring reminder a few days before any trip you have planned, so you have time to schedule services and make arrangements without rushing at the last minute.
