Why Are Some People More Likely to Get Bitten By Mosquitos?

And by "some people" I mean me. Why is it that an evening stroll leaves me feeling eaten alive while my companions are left blissfully un-bitten?

First of all, it's probably not all in my head (although it could be — most people are bad sources about their own mosquito attractiveness). Studies suggest that about 20 percent of people are "high attractor types" who are especially appealing to the female mosquitoes seeking out blood for the extra protein they need to lay eggs. Of course, not all mosquitoes are the same. There are 150 different species in the United States, each with their own blood-sucking proclivities. But since you probably won't know — or care — if the bugger biting you is Culex pipiens or Aedes aegypti, let's consider some of the more general properties that affect your mosquito appeal.

Clothing Color

It's true, mosquitoes have discerning fashion taste. Or at least, they're more likely to spot you as a target if you stand out from your environment. Dark colors, especially, will attract more of the insect.

Movement

Similarly, the more you move, the easier you are to identify as a living, breathing, vessel full of delicious blood.

Body Heat

Visual clues allow the mosquito to locate you from relatively far away, but as she approaches, it's your body heat that draws her in. This puts pregnant women, who average about 1.26 degrees Fahrenheit warmer than others, at a particular risk — a fact which has been substantiated by a number of studies.

Carbon Dioxide

This is another reason pregnant women are at a disadvantage. Mosquitoes can detect carbon dioxide using a special organ called a maxillary palp from as far as 164 feet away. Since everyone emits CO2 simply by exhaling, it comes down to relative amounts. Unfortunately for mothers-to-be, pregnancy causes women to emit 21 percent more CO2. This is also why kids are often safe from bites, when bigger, more CO2-emitting adults are around.

Alcohol Intake

On the flip side, pregnant women are (presumably) avoiding another mosquito attractor: alcohol.For More and Original Article
