What is put foil on door knobs?

There are several reasons why someone might want to put foil on door knobs:

1. To prevent germ transmission: When foil is placed over a door knob, it can act as a barrier that prevents germs and bacteria from spreading. This can be especially useful in communal spaces, such as offices or public restrooms, where multiple people may touch the same door knob.

2. To protect against static electricity: Foil can also be effective in preventing static electricity buildup. This can be helpful in dry climates or environments with a lot of synthetic materials, as static electricity can cause discomfort or even damage to electronic devices.

3. To deter pests: Some people believe that wrapping door knobs in foil can deter pests like mice or insects. While there is no scientific evidence to support this claim, it may be worth a try if you are dealing with a pest problem.

Overall, placing foil over door knobs can be a simple and effective solution for a variety of problems. However, it's important to note that this method may not be practical or necessary in all situations.
