Most of us lock up, set the alarm, and head off thinking our homes are safe while we’re away. But criminals are getting smarter—and quieter. A subtle trick involving just a dab of glue or a strip of tape is becoming a favoured method for burglars to figure out if you’re home or not. It’s easy to miss, but once you know what to look for, you’ll never overlook it again.
A new tactic used to mark empty homes
Before you leave the house—especially for an extended period—take a quick look at your front door. Not the lock or the handle, but the edges. A growing number of burglars are using a thin strand of glue, carefully placed between the door and the frame, to test for activity.

Here’s how it works: the intruder applies a small dot of glue that connects the door to its frame. It’s barely visible, doesn’t interfere with opening the door, and dries quickly. If the thread breaks, it tells them someone’s been in or out. If it’s still intact days later? That’s a green light—no one’s home.
Some criminals go for a different version of the trick, placing tape over the doorbell to trigger a continuous ring. If no one removes it or answers, it’s another signal that the house might be empty.
These tactics are particularly worrying because they’re silent, discreet, and don’t raise suspicion. They’re often used during routine scouting missions, where intruders dress like delivery drivers or residents just wandering the hallways.
How burglars know you’re not home
The scary part? These subtle clues give away more than you think. By returning at intervals to check the glue or tape, burglars can determine how long the home has been unoccupied—helping them plan the perfect time to strike.
In many cases, properties are marked well before a break-in happens. The glue may stay there for days before someone decides to act. If you see something unusual—tiny residue near the frame, odd marks on the bell, or anything that doesn’t belong—don’t ignore it.
What to do before going away
The good news? A few simple precautions can go a long way.
First, avoid posting holiday plans on social media. As tempting as it is to share your beach snaps in real time, you’re also advertising that your home is empty.
Next, talk to your neighbours. A trusted neighbour can keep an eye on things, collect post, or even pop in now and again to make the house look lived in. Watering your plants and drawing the curtains occasionally can make all the difference.
For extra peace of mind, look into your local “vacation watch programme”. In the UK, this can be done through neighbourhood policing teams. In other areas, schemes may allow you to register your absence so that patrols can check on your property while you’re away.
Stay one step ahead
Burglars rely on people being unaware of these quiet little tricks. But now that you know what to watch for, you’re already better prepared.
If you ever spot a glue thread or mystery tape on your front door, don’t touch it immediately. Take a photo, alert the authorities, and check with neighbours to see if they’ve noticed anything strange too. Being observant, cautious and connected to your community is still the most powerful form of protection.
In the end, it’s the small details that matter. Just as they use them to find out if you’re not home, you can use them to prove you’re not an easy target. Stay sharp, stay safe—and next time you lock the door, check the frame too.
