Mosquitoes do, indeed, find some people more attractive than others. Dark clothing, blood type, sweat, carbon dioxide, pregnancy, skin bacteria, and beer consumption are some things researchers have found tend to draw mosquitoes to someone.
You have genes that advertise your blood type.
About 85 percent of people give off a chemical signal through their skin that indicates their blood type. If you're one of them, mosquitoes will find you particularly appealing — no matter what blood type you are.
The Rules of Mosquito Attraction
That means people who have a high metabolic rate and emit more carbon dioxide, including those who are pregnant, working out, or drinking alcohol tend to be more attractive to mosquitoes. The question of whether mosquitos prefer a certain blood type is controversial.
It has taken decades of research, but scientists are close to working out why mosquitoes bite some people, and not others. It comes down to a complex trifecta of carbon dioxide, body temperature and body odour that makes some people more inviting to mozzies than others.
But, the study concluded, “[i]ndividuals with a higher microbial diversity […] are less attractive to mosquitoes and may therefore receive fewer bites.” Our skin microbiota is influenced by our genetics, age, and immune system, something we cannot really do much about.
It also could mean you've developed an immunity to mosquito bites. "When a person has had repeated exposure to the mosquito allergen, her immune system can stop recognizing the allergen as a problem, and there is no reaction," Murphy says.
Blood Type
Not surprisingly—since, after all, mosquitoes bite us to harvest proteins from our blood—research shows that they may find certain blood types more appetizing than others. One study found that in a controlled setting, mosquitoes landed on people with Type O blood nearly twice as often as those with Type A.
Wear long, loose clothing in light colors like white, cream, and tan to make yourself less of a mosquito target. Spray insect repellents like DEET or picaridin on your skin to keep mosquitoes away. Use unscented body wash and shampoo to smell less attractive to mosquitoes.
Mosquitoes are turned off by several natural scents: cinnamon, peppermint, cedar, citronella, lemongrass, patchouli, catnip, lavender, and more. Find a favorite, and use it when you want to spend time outside.

As has been found in previous studies, more mosquitoes seemed to prefer people whose scent contained a blend of carboxylic acids, the oily secretions that hydrate and protect our skin. Two of those carboxylic acids are also found in Limburger cheese, McMeniman notes, a known lure for mosquitoes.
Your Feet Stink
The short answer as to why mosquitoes go after feet and ankles is that our feet often carry a strong odor. Yes, stinky feet attract mosquitoes.
Allergic reaction. Most people won't have severe symptoms after being bitten or stung by an insect, but some people can react badly to them because they've developed antibodies to the venom. You're more likely to have an allergic reaction if you're stung by an insect.
Fleabites may group into clusters or lines. The bites sometimes appear in a straight line of three or four bites. Fleas bite whenever they get the chance.
Several skin conditions can cause itchy lumps that resemble bug bites. These include allergic reactions, infections, and chronic conditions. Most people experience this symptom at some point. Itchy bumps can appear as a result of allergies, infections, insects, and, sometimes, nonidentified factors.
Mosquitoes find some people tastier than others. But a widespread notion is that women, to mosquitoes at least, are the sweeter sex, supposedly because estrogen is a strong attractant. In reality, gender does play a role, but not in the way most people think.
New research analyzes the interplay between soap scent, the body's unique odor profile, and mosquito attraction. Researchers say coconut-scented soaps were among the most effective at repelling mosquitoes.
About 85 percent of people give off a chemical signal through their skin that indicates their blood type. If you're one of them, mosquitoes will find you particularly appealing — no matter what blood type you are.
Sugary foods will definitely make you a target for these flying critters, as the smell of the sugar permeates the air and attracts not only mosquitos but other bugs.
Though they prefer direct access to blood, mosquitoes can bite through clothes if the fabric is thin and tight fitting. The pests' needle-like mouthparts pierce delicate cotton t-shirts with ease.
In addition, some have immunomodulatory functions. Over time, the exposure to mosquito saliva, with the repeated bites of these insects, lead to immunomodulation of the antiviral response occurring in the skin and nearby tissues.
Skeeter syndrome is a large local allergic reaction to mosquito bites marked by significant inflammation. If you have it, you're allergic to substances in the mosquito's saliva. Some people have so much swelling that they have trouble moving.
