Is it just a superstition or has some real significance?In many households, we see lemon and chilies are hanging at the entrance. But what is the real reason behind it? Is it to ward off evil spirits or is there some other more practical reason behind it?
In actuality, there is a scientific reason behind the superstition. Lemon and chilies, both have insecticidal properties which keep insects away. So, hanging lemon and chilies was a way to protect the house/shop from insects entering.
However, it must be admitted that in the present polluted environment, these simple natural insecticides don't work very effectively.
