Carbon dioxide

According to a study published by Nature, mosquitoes have olfactory cells called CPA neurons , which are capable of detecting the amount of carbon dioxide we emit, one of the main factors that they take into account when selecting their victims.

A human being generates every day around of a kilogram of CO2 , and every time you exhale, about 13 times per minute, it produces more than one hundred milligrams, although the exact amount depends on the metabolism, diet and physical exercise performed by the person in question.

For mosquitoes, a greater amount of carbon dioxide means that there is a lot of fresh blood to that attack, therefore, select the people who emit more CO2.
