why do mosquitoes bite me so much

Mosquitoes tend to bite some people more than others due to a combination of factors including body odor, carbon dioxide exhalation, body temperature, skin bacteria, genetics, and even blood type. Mosquitoes are attracted to certain chemical compounds like lactic acid and ammonia found in sweat, and some people naturally produce more of these compounds, making them more appealing. People who exhale more carbon dioxide, have higher body temperatures, or wear certain colors (like red or black) also tend to attract more mosquitoes. Additionally, specific skin bacteria and genetics influence individual attractiveness to mosquitoes. Some blood types, particularly type O, have been found to be more attractive to mosquitoes in studies. The immune system's reaction to mosquito saliva causes itching and swelling after bites. Overall, why mosquitoes bite some people more is largely related to their unique scent profile and physiological traits.
