Mosquito fact #5
Mosquitoes are attracted to humans by several main chemicals, carbon dioxide being the most recognized attractant. Different body odors as sweat, lactic acid, octenol as well as body heat and moisture also attract these biting insects. Visual cues as movement or dark color lure mosquitoes too. People drinking beer have been shown to be more attractive to mosquitoes, but ingestion of garlic or vitamin B12 has been proven to have no impact on mosquito biting in laboratory.
