Is it true that mosquitoes are attracted to the carbon dioxide that humans exhale?

Yes. A peer-reviewed review concludes carbon dioxide acts as an attractant mediating mosquito orientation toward hosts, and a 2017 report states human-emitted CO2 is a well-known homing beacon for female mosquitoes. Several other studies list CO2 among known mosquito attractants or confirm a CO2-detection pathway in host seeking.
