One of the most common reasons for such fear is the obnoxious, and unnecessary sound of a slamming door. It scares you a lot when you are home alone at night. 

Don’t worry a simple and quick solution is here.

A simple rubber band makes your day.

Just attach a rubber band to both sides of your doorknob in a twisted manner. The rubber band creates a barrier between the knob and the door frame and prevents interference with the latches. 

The rubber band will prevent the scary and rude noise from your door whenever you open and close it.

Caution: A rubber band at both sides of your doorknob keeps your door open, so avoid using this at the main door of your home otherwise it could be an easy invitation to the burglars. 

Put A Glass Or A Mug On Your DoorKnob

You can also try this to catch the intruder at night when you are sleeping. Just put a glass or a mug on your door handle or doorknob from inside. At night when someone tries to rotate the doorknob from outside, the glass or mug will fall and make a loud noise.

This sort of adjustment on your doorknob will alert you and could save you from something bad happening.

What To Do If You Spot A Rubber Band On Your Door Knob?

If you spot a rubber band on your doorknob, it is a sign that someone is trying to get into your house. Do not attempt to remove it Instead, call your local police department and ask them to come to your home for an investigation. 

You must have heard about the incident that happened with Kim Fleming Cernigliaro. One day she was home alone and suddenly she encountered a loud and pondering knock-knock at the door.

The whole incident made her worried, she tried to figure out what was going on through the stained window glass. She saw a guy standing outside, whom she had never seen before. 

Suddenly a loud and disturbing knocking was stopped, she was scared and waited for half an hour before opening the door. She encountered a parcel a few steps away from the main door, and a rubber band fastened to the doorknob. 

She was really confused and immediately called the police for help. When the officers came they told about the same thing that had been reported by many people across the town. People got robbed when they opened their doors just after listening to the knock-knock at their main door. Later, the same rubber band was found tied to their doorknob.

How does It work?

When homeowners open the door, the rubber band which is fastened around the doorknob makes its latch open and prevents it from locking the door when they close it after opening it. Now it becomes very easy to get inside the home because the homeowner will not be able to lock the door. 


Putting foil on the doorknob for safety may not be that much helpful. Installing CCTV cameras, security lights, and alarms are some great ways to stay safe and secure when home alone.

There are some benefits too of putting aluminum, and tin foil around the doorknob that I’ve mentioned in this article. I’m also aware of what to do if, you encounter a rubber band tied to your doorknob.
