Why Is It Used?
The goal is simple: to test if a home is occupied.
If the wax stays undisturbed for several days, it may signal that:
-
The property is vacant or unmonitored
-
The house could be a target for break-ins
These techniques are often used alongside other suspicious behaviors, such as:
-
Flyers or fake business cards placed on doors
-
Knocking to “check for interest”
-
Marking curbs, mailboxes, or light posts nearby
Other Strange Markings and What They May Mean
-
Chalk or marker symbols on driveways or curbs
-
Pebbles or sticks arranged near doors
-
Thread or string tied to fences or door handles
-
Dots, stickers, or small tags on windows or mailboxes
While some of these may seem random or innocent, they have been observed in neighborhoods before reported burglaries—especially in urban and suburban areas.
