    Researchers identify a compound secreted by the human body that can actually block the smell of mosquitoes.

    Previously published researched revealed that mosquitoes prefer certain blood types and humans secrete a chemical to let mosquitoes know that you are “their type.”  A new study presented at a meeting of the American Chemical Society found that Lactic acid, a common component of human sweat, was a top lure for mosquitoes.  But scientists also discovered that the substance 1-methypiperzine that naturally occurs in human skin, can actually block a mosquito’s sense of smell.  They say the compound could be synthesized for use in lotions, cosmetics, and clothing.  One researcher put it in plain English, “if a mosquito can’t sense that dinner is ready, there will be no buzzing, no landing, and no bite!”
