Mosquito bites are an irritating experience for anyone. But to some, it is more unbearable than the others because they seem to attract more mosquitoes in general. Here are some of the potential reasons why a person might be such a mosquito-magnet.


According to Time, one of the primary reasons some people attract more mosquitoes than the others is the intensity of their breath. These insects are drawn by CO2 released by the human body as it burns energy as a part of their metabolism.

In fact, the CO2 emission is one of the major ways in which mosquitoes identify their bite targets, according to Dr. Jonathan Day, a medical entomologist and mosquito expert at the University of Florida.

“All vertebrates produce carbon dioxide, so what better way could there be for a mosquito to cue in on a host?” Day stated, as per the source.

Despite all the diet and exercise that you can perform to moderate your metabolism rate, one can only do so much. It has also been found that mosquitoes are drawn toward the lactic acid produced by the skin.

This primary technique for identifying targets aside, mosquitoes also rely on several secondary cues to differentiate a better bite target from other CO2-producing objects.

They prefer dark clothing to other light outfits. Mosquitoes tend to differentiate their host by comparing their silhouette to the horizon. So, wearing dark colors makes you stand out.


If one is making a lot of motion while wearing a dark outfit, it is a perfect way of inviting the winged insects for a bite.

According to a 2002 study, consumption of alcohol was also found to be a major reasons mosquitoes get attracted toward someone. Drinking alcohol not only raises one’s metabolic rate but also feeds their body with ethanol, which is attractive to the mosquitoes.
