a new technique has been developed to kill the dengue causing Aedes Aegypti mosquitoes. Rays emitting from dried marigold flowers dipped in 100 per cent alcohol and ground into a fine paste can keep the deadly mosquitoes at bay. Arun Patnaik of the Indian Institute of Sciences, Bangalore, who has done a detailed study on the behaviour of these mosquitoes, claims that the simple paste kept in a room can kill both the mosquitoes and its larvae within its 15 metre radius. "The concoction is best effective in sunlight as the sun's rays help releasing Alpha-T and Enithrocin which is the best insecticide available. Above all, it is bio-degradable and has no side effects," he says.
Patnaik has also come up with home remedies to prevent mosquito bites. He says by applying haldi powder (turmeric) on exposed areas and then washing it away with water while bathing can prevent mosquitoes bites. Another technique is by mixing a few drops of neem oil in the kerosene lamp before lightning, can also kill all kinds of mosquitoes within a radius of 15 metre.
