Avoiding mosquito
bites should be your first line of defense, but if the little
bloodsuckers bite, you'll need even more defense against itching
and infection.
Mosquitoes are insects that have been
around for more than 30 million years. And it seems that, during
those millions of years, mosquitoes have been honing their
skills so that they are now experts at finding people to bite.
Mosquitoes have a battery of sensors designed to track their
prey, including:
Chemical sensors - mosquitoes can sense
carbon dioxide and lactic acid up to 100 feet (36 meters) away.
Mammals and birds gives off these gases as part of their normal
breathing. Certain chemicals in sweat also seem to attract
mosquitoes (people who don't sweat much don't get nearly as many
mosquito bites).
Visual sensors - if you are wearing
clothing that contrasts with the background, and especially if
you move while wearing that clothing, mosquitoes can see you and
zero in on you. It's a good bet that anything moving is "alive",
and therefore full of blood, so this is a good strategy.
Heat sensors - Mosquitoes can detect heat,
so they can find warm-blooded mammals and birds very easily once
they get close enough.
