CNN —Anyone who has spent a summer evening swatting away mosquitoes, or a summer day scratching mosquito bites, can agree: Mosquitoes stink. In a scientific report published Friday, scientists helped pinpoint the different chemicals in body odor that attract these insects by building an ice-rink size testing arena and pumping in the scents of different people. Hundreds of mosquitoes in the main 20-by-20-meter facility were then treated to a buffet of the sleeping subjects’ scents. The researchers found what many who have been on a picnic would attest to: Some people attract more mosquitoes than others. (Vosshall said that even scrubbing with unscented soap doesn’t get rid of the natural scents that attract mosquitoes.)
