Why is that? It’due south non that we’re especially unlucky. In that location are actually scientific reasons why mosquitoes single out certain people. Here’southward exactly why mosquitoes bite, and how you tin brand yourself less of a target this summertime. (Yous tin besides notice out

Why do mosquitoes bite?

Reverse to what you lot might think, mosquitoes don’t bite people for food — they feed on plant nectar. Only female mosquitoes seize with teeth, and they practice so to receive proteins from your blood needed to develop their eggs.

Why are some people more than decumbent to bites?

At that place are several factors that bear on why some people are more prone to musquito bites than others:

Clothing color

Mosquitoes are highly visual hunters when it comes to finding a man to bite. This means movement and dark clothing colors like black, navy and crimson can stand up out to a mosquito. Research has shown that mosquitoes are more attracted to the color blackness, but in that location has been fiddling additional research into why this is the case.

Carbon dioxide

Mosquitoes use sight and smell to find hosts to bite. One of the quickest ways mosquitoes tin sniff out a person is through the carbon dioxide emitted when nosotros breathe. According to research published in the journal Chemical Senses, mosquitoes apply an organ called a maxillary palp for carbon dioxide detection and can sense it from 164 feet away.

Considering carbon dioxide is a huge attractor, people who emit more than of it — larger individuals and people who are breathing heavily when working out — are more attractive to a musquito.

Torso scent and sweat

Mosquitoes are attracted to more substances and compounds than but carbon dioxide. Mosquitoes can find people to bite past smelling substances present on human skin and in sweat, including lactic acid, uric acid and ammonia.

Researchers are notwithstanding learning why sure body odors are more attractive to mosquitoes, but they do know that genetics, bacteria on the pare and practice all play a cistron. Genetics touch the corporeality of uric acrid emitted, while exercise increases lactic acid buildup.

Blood blazon

A common belief is that mosquitoes are attracted to certain
blood types, considering mosquitoes bite humans for their blood. Blood blazon is determined by genetics, and each blood type is created based on the different sets of specific proteins, called antigens, on the surface of red blood cells. In that location are four main claret types: A, B, AB and O.

While there are no firm conclusions as to which claret blazon is more than attractive to mosquitoes, several studies take suggested people with type O are most appetizing to mosquitoes. A 2019 study observed mosquito feeding behavior when presented with different blood type samples, and found mosquitoes fed from the type O feeder more than any other. A 2004 written report too found that mosquitoes land on blood group O secretors (83.3%) significantly more than group A secretors (46.5%).

Nonetheless, these studies are not definitive, and much is however up in the air about musquito preferences when information technology comes to blood type.


In a minor study, mosquitoes were observed to land on participants more oftentimes afterward they had drank a small corporeality of beer. But before you lot swear off beer for good, know that the study only had 14 participants, and information technology found that mosquitoes may only be marginally more attracted to people who take been drinking beer.

The size and severity of a seize with teeth relate to how your immune organization responds to the saliva introduced by the mosquito when it bites.

Why do some people not bad from mosquito bites more than than others?

Mosquito bites can range in size from pocket-size niggling spots to large welts. Why is this the case?

Bites affect people differently. The size and severity of a bite relate to how your allowed system responds to the saliva introduced past the mosquito when it bites. When mosquitoes seize with teeth, they inject some saliva when drawing blood. This saliva contains sure anticoagulant and proteins, triggering the allowed system to answer to these foreign substances.

Our torso responds past releasing histamine — a chemical that is released by white blood cells when your immune system is fighting against allergens — which causes the itchiness and inflammation of the bite.

Prevention and treatment of mosquito bites

The all-time way to handle a mosquito seize with teeth is to not get them in the first place — simply ofttimes times, that’s easier said than washed.

Some mutual ways to foreclose musquito bites include:

  • Use repellents and
    problems sprays
    (Repel, Off! Deep Wood, and other brands that contain DEET)
  • Use natural repellants (citronella
    essential oil, neem oil, thyme essential oil)
  • Avert going outside at dawn or dusk
  • Avoid dark-colored article of clothing, specifically black
  • Avoid standing water and endeavour to eliminate continuing h2o nigh your home
  • Employ mosquito netting when camping or sleeping outdoors

Mosquito bites, while annoying, are often not severe and will resolve in a few days. In the meantime, there are several treatments to alleviate the itchiness and inflammation:

  • Clean with rubbing booze if a fresh bite
  • Take an oatmeal bathroom
  • Use over-the-counter antihistamines such every bit Benadryl or Claritin
  • Apply mild corticosteroid creams
