Smelly socks used to lure mosquitoes into traps

The smell of old socks can help fight malaria by attracting mosquitoes to a trap outdoors, scientists have found, and on Wednesday donors announced new funding to help develop the device.

Traps scented with the odour of human feet attracted four times as many mosquitoes as a human volunteer, said Dr. Fredros Okumu, the head of the research project at Tanzania’s Ifakara Health Institute. Mosquitoes who fly into the trap are then poisoned.  source
