The mosquitoes are a family of small, midge-like flies: the Culicidae.
Although a few species are harmless or even useful to humanity, most
are considered a nuisance because they consume blood from living vertebrates, including humans.
The females of many species of mosquitoes are blood-eating pests. In feeding on blood, some of them transmit extremely harmful human and livestock diseases, such as malaria, yellow fever, and filariasis.
Mosquitoes are picky creatures unsurprising if you’re the one always ducking for cover under a swarm of
bloodsuckers while your friend remains unscathed.
Good thing scientists
are on the hunt to discover what makes certain people especially
attractive to the tiny insects. Here are some reasonable results they’ve come up
with so far.
You Breathe
In many ways, no one is immune.
The fact that humans breathe makes us all mosquito targets to varying
degrees. More than 30 years ago, researchers discovered that carbon dioxide
is one of the main reasons mosquitos seek us out.
The insects will fly
to higher concentrations of CO2 (i.e. - large groups of people at
sporting events and backyard parties), then use other sights and smells
to narrow down their target.
You’re Tall
Because larger people produce
more carbon dioxide and more body heat, they’re naturally more
attractive to mosquitoes. This is why, when in groups, adults usually
get bitten more than children, and men are targeted more often than women.
You’re Pregnant
Along with swollen feet and morning sickness, pregnant women are also nearly twice as likely to get bitten
than those who are not expecting, according to one international study.
Two reasons: Pregnant women produce excess amounts of carbon dioxide
and body heat.
You Exercise Regularly
During a workout, the body
produces a chemical called lactic acid, which is released through sweat
glands on the skin. And one German study confirmed that mosquitoes can detect and are attracted to lactic acid at close range.
Your Feet Stink
One study published in the
journal PLOS ONE found that people with a higher abundance but lower
diversity of bacteria on their feet are highly attractive to mosquitoes.
The bacteria, which is pungent, is also found in Limburger cheese and
is so effective at attracting mosquitoes, that scientists are using the
cheese to trap and control the flies in Africa.
You’re Wearing Perfume
Mosquitoes suck the nectar of flowers for energy, so they’re attracted to floral scents. And certain floral odors are effective enough that researchers are figuring out how to use them to lure mosquitoes with their sweetness.
Your genes are responsible for your body odor, so scientists are starting to test how genetic makeup could affect one’s susceptibility to mosquitoes. For example, one study published in the journal Infections, Genetics, and Evolution found that people with a particular HLA gene are more likely to be bitten.
You Drink Beer
Downing just one 12-ounce beer can increase the risk of being bitten, says the Journal of the American Mosquito Association, although it’s unclear why. Just make sure that backyard beer is worth it.
You Have O Blood Type
This one is debatable. Several studies, including the most recent published in the journal Experimental Parasitology,
show that people with blood type O are more likely to get bitten.
However Joseph M. Conlon, a technical adviser to the American Mosquito
Control Association, has disputed some of the research, blaming “bad statistics.”
