Herbal mosquito repellent prepared

A group of scientists of the North-East Institute of Science and Technology (NEISC), formerly known as Regional Research Laboratory (RRL), Jorhat, has prepared a safe mosquito repellent in the form of Agarbatti or incense sticks from a harmless bio-product. Most of mosquito repellents currently used for domestic purpose are mainly synthetic products with high mammalian toxicity. They are mostly synthetic pyrethroids. Though they are less harmful then general insecticides, but still are not totally safe for prolonged use, sources said.
