What Attracts Mosquitoes & Why Do They Bite You?

In this article, we’ll explain what mosquitoes are most attracted to.

We’ll also discuss and answer a few of the following questions:

  • What are mosquitoes attracted to in humans
  • Does sweat attract mosquitoes
  • Who mosquitoes bite & why

Lastly, we’ll share a few tips on how you can stop attracting mosquitoes, so they stop biting you so much.

Mosquitoes can ruin even the most beautiful summer sunset with their constant buzzing and biting.

Let’s go.

Why Do Mosquitoes Bite?

Mosquitoes are one of the most annoying and dangerous insects on the planet. They are known to carry deadly diseases, such as malaria, yellow fever, West Nile virus, dengue fever. Moreover, they can cause untold misery through pain from bites or cause itchy welts, becoming infected.

Scientists have studied the behavior of mosquitoes for many years and found out what attracts mosquitoes. Mosquitoes bite us because the human skin emits heat and carbon dioxide. However, a particular type of sugar is emitted from the skin, which draws them to us as if we were just another juicy plant-bearing fruit in an open field.

The mosquitoes that spoil your summer are primarily female, and they feed on the blood of humans because they need to produce eggs. They can easily pierce through the skin with their mouthparts, which is perfect for sucking up some tasty human plasma.

Male mosquitoes have no use for this as they do not reproduce or lay eggs – so females mainly rely on a diet of protein found in our blood!

Where Do Mosquitoes Like To Bite?

To get a blood meal, mosquitoes bite any part of the skin they can get access to. It is, however, possible that they prefer certain parts of our body. Therefore, they are likely to target areas such as hands, wrists, feet, and ankles.

Also, contrary to popular belief, it has been found that mosquitoes use the carbon dioxide emitted by humans for locating them instead of biting areas that release more carbon dioxide.

Why Do Mosquito Bites Itch So Much?

Mosquitoes bite and inject saliva into your bloodstream, which can lead to an itchy, red rash. The reason for the sudden itching is that your immune system reacts to the chemicals present in mosquito saliva when they bite you.

Histamines are a natural response to mosquito bites and can produce itchiness, swelling, and redness in the area around them. In addition, histamines have vasodilatory properties that reduce blood flow, which reduces the oxygenation of tissue.

What Are Mosquitoes Attracted To?

Carbon dioxide

Mosquitoes use several methods to locate us. Specifically, they are attracted to the carbon dioxide that humans exhale as well as body heat. This is because mosquitoes use these compounds and other factors, such as body movement, to locate their prey.

So, if you’re not breathing hard or sweating on account of exercise, then there’s less chance of being bitten by one.

Researchers have discovered a type of nerve cell in female mosquitoes that they use to detect carbon dioxide. It’s through these cells, which are found only on the mosquito’s antennae and ocelli (eyespots) that scientists believe females can sense our breath from up to 20 feet away.

Body odor

You might be wondering, ‘why do mosquitoes bite me’? The answer is because of your body odor, which is determined primarily by genetics. Thus, if you are related to someone who gets bitten by mosquitoes, often, chances are you will also be subjected to the same fate.


Dark colors like black, navy blue, and floral attract mosquitoes to humans and are universally known to be mosquito magnets. Scientists know that mosquitoes prefer darker colors because they reflect the heat well but don’t understand why this is true.

Heat and water vapor

Mosquitoes have an incredible sense of smell, which can help them detect the heat and water vapor levels present on our skin, causing them to move towards a source they find more appealing. They generally rely on their keen senses of sight (sighting prey at night) and hearing (detecting sources within the desired temperature). But recent studies show that female mosquitoes also use olfaction as part of hunting down hosts.

Mosquitoes also seem drawn to your blood’s unique scent, mainly due to the compounds’ compounds during digestion. It could be that these odors are powerful because you happen to be dehydrated, making it possible for you to attract more mosquitoes.


‘Why do mosquitoes bite me more than others is something we all have pondered upon at some point. Mosquitoes don’t just happen to find you; they develop a liking for a specific host. They learn and develop an affinity towards certain hosts after being exposed to the sights, sounds, and smells of previous successful attacks on that particular host. Thus, they are more likely than not drawn back to the same host as soon as possible.


It’s hard to believe that mosquitoes have a taste for beer and alcohol. A study found that more mosquitoes landed on participants who drank 12-ounce more beer than before. The reason for this, however, remains unclear.

study in Africa found that mosquitoes were attracted to pregnant women when compared to non-pregnant women. One explanation for this can be that pregnant women exhale twice as much carbon dioxide as those who are not pregnant.

Researchers also learned the bodies of pregnant women (especially their abdomens) emit 0.7 degrees more heat than non-pregnant women, which makes them attract more mosquitoes.

What Attracts Mosquitoes To People?

Your smell

Scientists at the University of California in Los Angeles have recently identified that odors released through perception are likely to attract mosquitoes. These specific substances include ammonia, lactic acid, and uric acid, leading these insects towards humans for an easy meal.

A higher body temperature is another factor, as a human’s increased metabolism causes sweat. This leads them to be more attractive targets than others who may not sweat as often. The areas exposed, such as hands, wrists, feet, and ankles, play hosts because they retain moisture from outside air sources. Bacterial colonies thrive easily among open skin pores, making them perfect food gathering areas for mosquitoes.

Reasons That Are Not in Your Control

There are many reasons why mosquitoes bite; however, there are reasons out of your control. As demonstrated by Japanese researchers, those with Type O blood were bitten more than those who had Types A or AB in their blood.

Your metabolism is to blame as it regulates bodily functions, such as heat production, and as we know, mosquitoes are attracted more to warmer temperatures. Some people are more likely to be bitten by mosquitoes than others is also determined by how attractive you smell to a female mosquito.

So, if you have the wrong combination of DNA, it will make you an easy target for those pesky insects. As much as 85% of your genetic makeup is responsible for making you a mosquito magnet.

Why Are Mosquitoes Attracted to Some People More Than Others?

There are around 400 chemical compounds that play a role in attracting mosquitoes to the human skin. The most famous study about malaria-spreading mosquitoes is one that outlines how they are attracted to Limburger Cheese. You may be surprised to know that the same bacteria responsible for giving this cheese its distinctive smell also lives in our toes and explains why mosquitoes find your feet so appealing.

Mosquitoes are challenging to study because they vary between species, and the thing about mosquitoes is that it’s not just one type of mosquito. There are many, and each has different habits for biting people. When scientists did a similar experiment on another kind of mosquitos (Aedes aegypti), the same phenomenon, as observed in the previous study, did not repeat.

Are Mosquitoes Attracted To Sweat?

Mosquitoes have a few preferences when choosing their next meal: they prefer sweatier areas, as these are the easiest for them to detect. Mosquitoes like the human feet because of the strong odor emitted from this area due to some people’s horrible foot hygiene habits.

Certain compounds present in sweat and on the human skin are what attract mosquitoes. For example, lactic acid, ammonia, and other enticing aromas that we emit when sweating attract mosquitoes to bite you.

At this point, you might be asking yourself, ‘why don’t mosquitoes bite my pits as they’re sweatier’? However, it’s obvious that, unlike your feet, the arms tend to stay covered.

Mosquitoes can detect sweat through their antennae, which can detect the lactic acid in our sweat. So scientists have been looking for ways of interfering with this receptor Ir8a and its signaling system.

They continue to examine how mosquitoes sense human odors, among other things, and are trying to find ways we might be protected from pathogens that mosquitoes spread.

How To Be Less Attractive To Mosquitoes?

One of the most common misconceptions is that wearing a lot of perfume will keep mosquitoes away. But, unfortunately, mosquitoes can smell right through any diversion, and even if you cover up your odor with heavy scents like cologne or strong fragrances, they’ll still be able to find you because their senses are so keen.

Since mosquitoes are a significant problem, they can carry dangerous diseases, and they’re always looking for new victims to bite, especially in the summer months. Therefore, it is essential to avoid standing water and use an insect repellant that will keep them away from you all day long.

Keeping mosquitoes away from you is not only about making yourself unattractive to them but also about implementing methods of mosquito control. One way is to create a mosquito-free zone at your home.

Another way you could keep mosquitoes away is by putting on some light-colored clothing. According to studies involving both lab tests as well as fieldwork with biting insects like mosquitoes, it is known that they don’t see very far into the color spectrum.

Thus, lighter colors will make you less detectable, whereas darker ones may act more attractive.

Some recommendations to avoid mosquito bites:

  • Keeping mosquitoes out of your house by using screens on doors, windows, and vents. This will help keep them from getting inside the home where they can bite you when enjoying a relaxing evening or during sleep time.
  • Getting rid of standing water is another crucial step because it’s a breeding ground for these insects. Just dump any items that hold water outside and make sure there are no containers with stagnant liquid indoors, including flower pots.
  • Dawn and dusk hours tend to be peak times for mosquitos, so avoid going outdoors during this time.
  • Wearing light-colored clothing also helps keep mosquitoes away as they are attracted to darker colors.
  • Wear long sleeves and pants because they will cover most, if not all, parts of your body. and prevent any unwanted bites from happening

Yes, mosquitoes are not only attracted to black but also towards other dark colors. However, black is the darkest color and will invite more mosquitoes.

Why Do Mosquitoes Bite Me And Not My Husband?

Mosquitoes may seem to bite you more and not your husband because of the difference in your genetic makeup. Mosquitoes are attracted to particular DNA, but other things such as the temperature between two bodies might draw them more towards the warmer body.
