What smells do mosquitoes like?

But it’s all about how you smell, whether it’s good or awful. Mosquitoes have a sophisticated sense of smell, allowing them to choose their favourite blood meal.

So, what do mosquitoes prefer to smell like? To learn more, continue reading.

7 Smells that Mosquitoes Like

The study of how mosquitos choose their prey is ongoing. However, one thing is certain. These insects have scent detectors that can tell them apart from their hosts from up to 100 feet away.

Mosquitoes are drawn to particular chemical smells more than others, as the human body emits almost 400 different chemical smells.

Different mosquito species have different requirements. While some feed on anything warm-blooded, others, including as Aedes aegypti (the Zika virus’s principal carrier), solely eat human blood.

It has been proved that certain odors we emit, whether consciously or unknowingly, such as carbon dioxide, attract certain animals.

Carbon dioxide

Mosquitoes are attracted to the CO2 humans breath, according to studies. Apparently, their sense of smell is more important than their eyesight in locating hosts.

They follow possible targets through CO2 emissions until they can see them. More importantly, these bugs are capable of detecting changes in CO2 concentration.

When one’s metabolic rate increases, more carbon dioxide is emitted into the atmosphere. Exercise, pregnancy, and alcohol raise CO2 levels in the body, signaling mosquitos to possible hosts.

Lactic Acid

Lactic acid is produced naturally by our bodies during the conversion of carbohydrates to energy.

During physical activity, this waste is expelled via the skin. It can also be found in foods such as kimchi, yogurt, wine, and sourdough bread.

Lactic acid levels vary from person to person and can be elevated through activity or consuming the foods specified.

Lactic acid attracts mosquitos, who prefer to bite active and larger persons.

odour of the body

Female mosquitoes employ a variety of methods to select their prey, including odor. These bugs are attracted to certain substances found in human sweat and skin.

Some people are more sensitive to mosquito bites than others due to various chemicals like ammonia and lactic acid.

Although the exact reason of body odor variation is unknown, some microbes and genetics play an important impact.


Mosquitoes are attracted to the scents included in personal care products. If we can smell you, you can bet these insects can as well.

So, what is it about deodorant that attracts mosquitoes? The feminine bloodsuckers, it turns out, enjoy sweet fragrances. Furthermore, most skincare products contain lactic acid, which is produced naturally by the human body through sweat.

Using such treatments, particularly those with floral scents, can only aggravate your issue and aid these bugs in finding you.

Do you wish to stay away from mosquito bites? If you expect to spend time outside, you should avoid wearing cologne or perfume.

Aren’t you eager to shake things up a little? Unscented body wash, shampoos, and lotions are always an option.

Bacteria on the Skin

Mosquitoes are generally attracted to what lives on your body rather than what you put in it. There are countless germs and bacteria in the human body.

Now, before you stress out and start cleaning your body with sanitizer, keep in mind that these germs are beneficial to your health. They are, in fact, essential in keeping you healthy by combating the bad ones.

Sweat is the most nutrient-rich environment for skin microorganisms. Some microorganisms are enticing to mosquitos, whereas others are not. Microorganisms thrive quickly in perspiration because of the plentiful proteins and minerals.

Have you ever noticed how diverse people’s perspiration smells? This is the fault of the bacterium. Their excrement has a characteristic odor that mosquitoes use to locate their prey.

Furthermore, no two persons have the same microbiome.

Type of Blood

Mosquitoes don’t choose their victims at random, as you probably already know. The blood group factor, however, is not something you can select or control.

There are four different blood group kinds, each with its own distinct aroma. According to the findings, these parasites are particularly drawn to type O blood, but not to type A.

If you’re a type O, you can always apply repellants to avoid getting bitten. Regardless of your blood type, make sure to take preventative precautions.

Vapor and Heat

Depending on the temperature in a region, the human body creates heat and releases vapor. The capacity of mosquitoes to detect these factors allows them to decide whether or not to bite.

In comparison to humans, animals have different levels of vapour and body temperatures. These characteristics come in useful when mosquitoes are looking for a new host, as humans are often attractive to them.
