Researchers in Israel have found a new way of repelling mosquitoes by using a chemical given off by their predators. Backswimmers prey on the mosquito larvae that hatch from eggs laid in stagnant pools. The aquatic insect releases a scent that female mosquitoes avoid. Humans cannot detect the scent. The researchers hope to use their findings to develop repellents. It is hoped that, unlike other repellents that have to be used all over the body, smaller amounts of repellent based on the chemicals released by backswimmers could keep mosquitoes at bay.
