It may look unusual, but wrapping your door handle in aluminum foil is one of the simplest home security hacks spreading across the internet. By tightly covering the handle before bed or while away, you create an instant tamper detector—any wrinkles or dents the next day reveal that someone tried to open your door. It’s a low-cost, silent warning system that even seasoned burglars don’t expect.
The foil serves double duty too. If an intruder touches the handle while you’re home, the crinkling sound alerts you immediately. Add a cup balanced on the inside handle for a loud crash if the door moves, and you’ve built a surprisingly effective early-warning trap. Combined with outdoor lighting, smart locks, and security cameras, this simple foil trick can turn your home into a far less tempting target. Sometimes, the smartest protection really does come from the kitchen drawer.
