Vectors of many diseases (the malaria, dengue fever, zika, etc.), mosquitoes are attracted by the carbon dioxide (CO2) emitted by the mouth and nose when breathing, but also by the heat emitted by the body (they perceive infrared) and by certain molecules present on the skin – lactic acid and ammonia, for example. These are only biting female mosquitoessince they need blood to reproduce.
