Mosquito repellents are must-have items in every house in India. Those are usually made with harmful chemical poisons.
Remember, if it's a poison for mosquitoes, it is also a poison for us.
I was always searching for an effective safe alternatives to those repellents and finally found it.
It's camphor!. Just crush one or two camphor and throw it on the bed. That's it!. The mosquitoes will be repelled by the perfume of camphor.
Enjoy the peaceful sleep :)
