Mosquitoes have a strong sense of smell, and they are attracted to certain fragrances in perfumes, colognes, lotions, soaps, and shampoos. Floral scents, sweet and flowery perfumes, and scented lotions are known attractants of mosquitoes. However, other scents, such as peppermint, lavender, lemongrass, garlic, vinegar, and citronella, are known to repel mosquitoes. While science is still learning about how mosquitoes choose their targets, it is clear that odor plays a significant role in their ability to detect and be attracted to potential prey.

What You'll Learn
Mosquitoes are attracted to fragrances like perfume
Mosquitoes have a strong sense of smell, and they are drawn to humans as a source of blood because of the carbon dioxide and fragrances we emit. They are attracted to certain fragrances in perfumes, colognes, lotions, soaps, and shampoos, particularly floral scents.
The female mosquitoes, which are the ones that bite, use odor as the primary indicator to choose their prey. They have sensitive antennae covered in tiny sensory structures called sensilla, which have receptors that detect odors in the air created by a warm-blooded host. When odor receptors catch a scent, they send signals to the mosquito's brain, and it follows the odor, using other sensory cues such as heat and humidity to guide its flight toward the source.
Therefore, if you want to avoid mosquito bites, it is best to avoid wearing perfumes, colognes, and other scented products that may attract them. Opting for unscented body washes, lotions, and shampoos can help reduce the chances of being targeted by mosquitoes. Additionally, mosquitoes are attracted to the lactic acid present in our bodies, especially when we work up a sweat, so maintaining proper hygiene and showering after workouts can also help reduce the risk of mosquito bites.
While some fragrances may attract mosquitoes, other scents can deter them. Natural scents like peppermint, lavender, lemongrass, garlic, and citronella are known to repel mosquitoes. These can be used in the form of essential oils, candles, or planted around your outdoor space to create a natural barrier against mosquitoes.

Carbon dioxide and lactic acid attract mosquitoes
Mosquitoes have a keen sense of smell, which is the primary reason they are drawn to humans and other animals as a blood source. They are attracted to the carbon dioxide we exhale, both the scent and the amount. Every time we exhale, we release chemicals like lactic acid, octenol, uric acid, and fatty acids that combine with CO2 to form a unique carbon dioxide cocktail. This combination of scents is what alerts mosquitoes to the presence of a human target nearby. The more CO2 we emit, the easier we are to detect. The scent and amount of carbon dioxide you exhale are unique to you and your genetics.
Lactic acid is emitted through the skin when a person is active or eating certain foods. Mosquitoes are attracted to people with higher levels of lactic acid on their skin. You can reduce the amount of lactic acid on your skin by washing with soap after exercising and thoroughly drying off.
The IR8a receptor plays a crucial role in human host-seeking behaviours in mosquitoes. They are also attracted to body heat, moisture, movement, and colour.
While perfumes may attract mosquitoes, it is important to note that the carbon dioxide we exhale and the lactic acid on our skin are significant factors in making us attractive targets for mosquitoes.

Natural scents like peppermint, lavender, and garlic repel mosquitoes
While some sources suggest that mosquitoes are attracted to the scent of perfumes, there are certain natural scents that are believed to repel mosquitoes. These include peppermint, lavender, and garlic.
Peppermint oil has been shown to be an effective mosquito repellent. The oil is derived from peppermint leaves, which are commonly used to add a refreshing flavour to drinks and chewing gum. In addition to repelling mosquitoes, peppermint oil has also been found to be effective against other pests such as fleas and ticks.
Lavender is another natural scent that mosquitoes are believed to dislike. Lavender contains a high amount of linalool, a compound responsible for its strong smell. The scent of lavender overwhelms the mosquito's sense of smell, making it an effective repellent. Lavender essential oil has an 80% repellent rate against mosquitoes and can be safely applied to the skin when diluted with a carrier oil. Growing lavender plants around your home is another way to take advantage of its mosquito-repelling properties.
Garlic is also known to be an effective natural insect repellent. The bulbs contain an amino acid that, when crushed, blended, or chopped, converts to a substance called allicin, which releases a strong odour. Eating garlic cloves is said to help keep mosquitoes away, and the oil extracted from garlic leaves is also effective as a repellent.
It is important to note that while these natural scents may help to repel mosquitoes, they may not be as effective as commercial insect repellents. Additionally, some individuals may have sensitivities or allergies to certain scents, so it is always a good idea to patch test any natural repellent before widespread use.

Mosquitoes are drawn to human body odour
Mosquitoes are attracted to human body odour, and they have a very keen sense of smell. This is the primary reason they are drawn to humans and other animals as a blood source. The carbon dioxide and many of the fragrances we emit are irresistible to mosquitoes.
Research has found that people with higher levels of certain acids on their skin, such as carboxylic acids, are more attractive to mosquitoes. These acids can produce an odour that smells like cheese or smelly feet. The composition of the skin microbiome is unique to each individual, and this can result in some people being more attractive to mosquitoes.
Mosquitoes are also attracted to body heat, lactic acid, and carbon dioxide, which is exhaled in higher amounts by people with a higher metabolic rate. They are also drawn to people who have consumed alcohol or are pregnant.
Some mosquito species have evolved to specialize in biting humans, and these species are often the most efficient and deadly vectors of human disease. Anopheles gambiae and Anopheles coluzzii are the primary vectors of malaria in Africa, while Aedes aegypti is the primary vector of dengue, chikungunya, and yellow fever worldwide. These species have a strong innate preference for human odour over the odour of animals, and this preference is displayed by females, who need nutrients from blood meals to synthesize eggs.
Overall, mosquitoes are drawn to human body odour due to a combination of factors, including the presence of certain acids, body heat, and carbon dioxide, as well as their evolutionary preference for human odour.

Store-bought repellents mask natural scents that mosquitoes like
Mosquitoes are attracted to certain fragrances in perfumes, colognes, lotions, soaps, and shampoos. They are also attracted to the carbon dioxide and lactic acid in our sweat. When exercising, our heart rate increases, causing us to sweat more and attract mosquitoes.
Store-bought repellents mask the natural scents that mosquitoes like by using scents that mosquitoes dislike. The most effective mosquito-repelling products recommended by the Center for Disease Control contain DEET, oil of lemon eucalyptus, and picaridin. DEET prevents mosquitoes from sensing human scent. However, DEET products can cause health and environmental problems and may lead to irritation, pain, watery eyes, swelling, redness, nausea, and vomiting in rare cases.
Natural repellents are a safer alternative to store-bought repellents, which may contain harsh chemicals. Natural mosquito repellent solutions can be easily created at home by mixing essential oils with a base of vinegar, witch hazel, coconut oil, or isopropyl alcohol. The key to avoiding mosquito bites is to prevent mosquitoes from being drawn to you in the first place.
There are several natural scents that mosquitoes find repulsive. These include citronella oil, which comes from the lemongrass plant and is commonly used in commercial bug sprays and candles. Marigold flowers, which contain the essential oil Nepetalactone, are approximately ten times more effective than DEET at repelling mosquitoes. Rosemary, a multipurpose herb, can be planted in the garden or placed on a grill to keep mosquitoes away with its scent. Lavender oil, which can be applied to the skin or made into a body spray, is also effective at repelling mosquitoes.
