• 🦟 Carbon dioxide, lactic acid, acetone, and ammonia are some volatile chemicals that attract mosquitoes.
• 🦟 Octanal, nonanal, decanal, and 6-methyl-5-hepten-2-one are chemicals that repel or impair mosquitoes' ability to find humans.
• 💪 Mosquito attractiveness is as hereditary as height and IQ, indicating a strong genetic influence.
• 🧑 Contracting malaria can change a person's body chemistry to make them more attractive to mosquitoes.
• 🥺 The evolution of malaria parasites has led to infected hosts producing an odor that attracts mosquitoes, facilitating the transmission of the disease.
