Why mosquitoes always choose you: the scientific explanation few know

Many people are familiar with this scene: an outdoor gathering, a warm and peaceful evening, and by the end of the get-together, one person has accumulated almost all the mosquito bites, while everyone else barely notices them. It doesn’t matter if repellent was used, if long clothing was worn, or if contact with grass was avoided. The feeling is clear: mosquitoes seem to have a very strong preference. Far from being a coincidence, this phenomenon has an explanation based on biology, body chemistry, and certain environmental factors that have a greater influence than many realize.

Mosquitoes don’t act randomly. Females, in particular, which are the ones that bite, need to feed on blood to complete their reproductive cycle. To achieve this, they’ve developed a highly sophisticated detection system that allows them to identify their ideal targets. In this process, the human body emits signals that function like a GPS for these insects.

One of the most determining factors is carbon dioxide. Every time we breathe, we release CO₂, and mosquitoes are extremely sensitive to this gas. People with greater body mass, greater height, or who engage in physical activity tend to emit higher amounts, making them more visible. Body heat is another key signal that guides mosquitoes to their food source.

Natural body odor also plays a central role. Human skin harbors millions of bacteria that produce specific chemical compounds. This combination is unique to each person and defines a particular scent. For mosquitoes, some of these odors are especially attractive. It’s not about dirt or hygiene, but a biological characteristic that makes certain individuals a better choice for their “food.”
