How Mosquitoes Use Visual Cues and CO2 to Hunt Humans

Have you ever wondered how mosquitoes find their targets so easily?

First, at a long range, they detect carbon dioxide (CO2) in our breath.

This CO2 acts as an activator, triggering their instinct to hunt.

Finally, once very close, they use thermal sensors and skin odors to finish the hunt.

Interestingly, when both CO2 and visual signals are present, mosquitoes perform an 'orbiting' behavior, circling the target before landing.
