While it might sound unconventional, wrapping your door handle in foil can act as both an early warning system and a subtle deterrent for potential intruders.
How the Trick Works
The idea is simple. Before going to bed or leaving the house, wrap a layer of smooth aluminum foil tightly around your outside door handle. When you return, check the foil — if it’s wrinkled, dented, or torn, it could be a sign that someone tried to open the door while you were away. This quick visual cue can alert you to suspicious activity without any fancy equipment.
