    When an adult female mosquito needs a blood meal to feed her young, she searches for a host — often a human.
    Many insects, mosquitoes included, are attracted by the odour of the carbon dioxide (CO2) gas that humans and other animals naturally exhale.
    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.

    It goes like this:

    10-15 Metre range: Mosquitos detects CO2 Plume (from human breathing)
    5-10 Metre range: Mosquitos eye humans
    ≈ 20 Centimeter range: Mosquitos detects thermal Plume and Moisture
