- Are the localized concentrations of CO2 around people sufficient to attract mosquitoes?
It's commonly said that mosquitoes are attracted by carbon dioxide - so I'll guess that there's empirical evidence for that assertion. But is the mechanism for this known? What is the localized concentration of carbon dioxide around a person respiring at a normal rate? Do we know that it's the higher carbon dioxide concentration that attracts mosquitoes - or could the detection be based on the lower concentration of some other gas that is being displaced by the CO2?
