Why mosquitoes bite some people more?

Answer: Body odor and CO2 levels

Body odor and CO2 levels ✓ — Correct! Mosquitoes are attracted to CO2 from breath, body heat, and specific body odors created by skin bacteria. People with more skin bacteria, higher body temperature, or blood type O get bitten more. Pregnancy increases CO2 output, making pregnant women mosquito magnets. Genetics affect body odor too!

Wearing bright colors — Wrong. While mosquitoes can see colors, this isn't a primary factor. Dark colors might retain more heat (which attracts them), but chemical signals like CO2 and body odor are much more important.

Eating sugary foods — Wrong. Eating sugar doesn't change your blood chemistry enough to attract mosquitoes. However, drinking beer can increase attractiveness slightly, possibly due to increased body temperature and changed skin emissions.
