Currently, 20% of people in the world are highly attractive to mosquitoes. The reason lies in their genetics and body odor. Mosquitoes are drawn to the carbon dioxide emitted by the body and the unique scent of an individual. If your metabolic rate is high, you're more likely to attract a swarm of mosquitoes. Some people tend to get bitten on specific body parts, such as legs, feet, or elbows. This is because certain bacteria on these areas act like magnets, attracting mosquitoes. Additionally, high levels of lactic acid in the body (released after exercise), certain compounds in breath, and high estrogen levels can also attract mosquitoes.
