Weekly Safety Topic – Mosquito Targets

Have you ever felt like you’re being specifically targeted by mosquitoes when you end up with itchy welts all over your body, while your friends seem like they’re not even aware of the pesky biters’ existence?
Well, it’s not your imagination. Research has proven that mosquitoes DO have preferences when it comes to picking out the people they want to suck blood from.
In a feature by the University of Florida it posted that “one in 10 people are highly attractive to mosquitoes”.  Here’s the thing – mosquitoes don’t suck blood for food. In fact, only female mosquitoes bite people because they need proteins from human blood to develop fertile eggs and create more mosquito babies.

The study also found 85 percent of our likelihood to get bitten by mosquitoes is due to genetics. So why are some people more susceptible to mosquito bites than others?

  • You have Type O blood Some blood types are indeed sweeter than others, metaphorically speaking. A study found that people with Type O blood are 83% more likely to get bitten. People with Type A blood are least likely to become mosquito prey, while those with Type B blood are kind of in the middle.
    In addition, 85% of people produce a secretion that signals their blood type, making them more obvious prey for mosquitoes compared to the non-secretors, regardless of blood type.
  • You have a large body size This has to do with your metabolic rate, or the amount of carbon dioxide (CO2) released from your body as it burns energy. Mosquitoes use CO2 as their primary means of identifying targets and can sense CO2 from up to 150 feet away!  Larger people tend to exhale more and give off more carbon dioxide, which is why mosquitoes prefer to go for adults over children. Men are also more likely to be bitten by mosquitoes compared to women, as well as obese or overweight people due to their larger body size and relative heat.
  • You’re pregnant According to a study done in Africa, pregnant women are twice as likely to attract mosquitoes compared to their non-pregnant peers because they give off a greater amount of CO2. In fact, a 2002 study found that women in the later stages of pregnancy exhale 21% more CO2 than non-pregnant women, making them even more noticeable to the pests.
  • You’ve been exercising or exerting yourself physically Mosquitoes are attracted to lactic acid, a compound produced by the body after working up a sweat.  In addition to the sweat, warmth becomes more attractive to mosquitoes as they approach a potential victim.
  • You’ve just had a beer or a glass of wine Drinking alcohol also raises your metabolic rate and your body temperature, making you very appealing to mosquitoes.
  • You’re wearing red or dark-colored clothing Apart from smell, mosquitoes also rely on sight to spot their prey. Red makes you a prime target, as well as dark colors such as black and blue.  Mosquitoes have problems flying in even a slight wind, and so they keep close to the ground. They spot hosts by comparing your silhouette to the horizon. Dark colors stand out, while light shades blend in.”

Certain elements of your body chemistry are calling out to the mosquitoes People who produce excess amount of certain acids (e.g. lactic acid, uric acid) tend to attract mosquitoes.

On the other hand, one study found that people who are bitten less frequently seem to “smell differently to mosquitoes”, almost as if they produce a natural repellent………….. Ugh, aren’t they the lucky ones!!??!!
