This enables them to sense the plumes of air we exhale. But mosquitoes are still attracted to human skin even in the absence of carbon dioxide.

Can mosquitoes sense humans through sweat?

How do mosquitoes know you are near?

However, mosquitoes can also pick up other cues that signal a human is nearby. They use their vision to spot a host and thermal sensory information to detect body heat.
