Are You A Mosquito Magnet?

0 147

Research is revealing that mosquitos are downright picky when choosing who to bite. It turns out there are many reasons why a mosquito targets certain people over others. Scientists believe that 85 percent of your overall attractiveness to mosquitos is based on your genetics. Unfortunately, you can’t change your genes.

But, you can arm yourself with knowledge. The following information can help you narrow down why you might be a mosquito magnet and ways to prepare for your next outdoor adventure.

Skin Bacteria

The bacteria on your skin have a lot to do with how you smell. In fact, human sweat is odorless to other humans if no bacteria are present.

Certain chemicals released by bacteria are what make body odor. And each person has their own unique bacterial mix, which creates their own personal scent.

It’s been found that mosquitos are attracted to certain bacterial scents more than others. Which means, if you naturally have more of those bacteria on your skin, mosquitos will pick you out of a crowd.

Also, certain mosquitos prefer different smells from different parts of your body. Some mosquitos will bite your feet or hands, whereas others go straight for areas like your groin or armpits.

Genetics play a significant role in what types of bacteria live on your skin. There may be other factors that influence your skin microbiome as well, such as diet, although research hasn’t determined exactly what yet.

Blood Type

Mosquitos are shown to prefer people with Type O blood. Before they take a bite, mosquitos can taste your skin’s secretions to determine your blood type. This allows them to easily select their favorite victims.

Type B blood is their next favorite, and Type A blood is their last pick.

Carbon Dioxide

Mosquitos are attracted to carbon dioxide. They have specialized receptors that can detect a carbon dioxide source from over 50 meters (164 feet) away. This is not good news for humans because we exhale carbon dioxide whenever we breathe.

This also means anyone who produces larger amounts of carbon dioxide is at a greater risk of being bitten. Evidence shows that people who are larger, such as those who are tall or overweight, will naturally produce more carbon dioxide.

You also produce more carbon dioxide when you exercise, so watch out when you’re gardening, jogging or doing any other outdoor activity.

Using a fan nearby can help break up your exhaled carbon dioxide trail and also physically throw a mosquito off course.

Heat

Mosquitos typically bite where blood is closest to the surface, like your forehead, elbows, wrists or neck. They use your body’s heat to hone in on the best locations.

Be careful during and shortly after exercising. Your body is hotter overall at these times and could attract more mosquitos.

Pregnancy

A Sudanese study found that pregnant women are nearly twice as likely to be bitten compared to non-pregnant women. Researchers suggest this may be due to specific pregnancy-related substances that are released in your breath and skin.

Pregnant women also naturally produce more carbon dioxide and their body temperature is higher, which could add to their mosquito attraction.

Sweat

Lactic acid is a key component of sweat, and it’s shown to attract mosquitos. In addition, sweat that has “aged” for a day or two has been found to be even more appealing to mozzies.

Researchers suggest that day-old sweat has higher amounts of natural bacterial growth from your skin. The smell from the bacteria is likely what attracts mosquitos in higher numbers.

So, make sure you shower after periods of exertion and sweating. It will help keep the bugs away, and perhaps even better, will also improve your popularity with people.
