What Smells Attract or Repel Mosquitoes in North Carolina?
Mosquitoes can turn a peaceful evening outdoors into a frustrating battle against itchy bites. However, understanding the scents that attract and repel mosquitoes can be a game-changer for creating a more enjoyable outdoor experience. In this blog, we'll delve into the scents that attract mosquitoes and those that deter them, helping homeowners in North Carolina reclaim their outdoor spaces.
The Strong Sense of Smell in Mosquitoes
Mosquitoes may be tiny insects, but they possess a remarkable sense of smell that plays a crucial role in their behavior and survival. Understanding how mosquitoes detect scents can provide valuable insights into how to repel them effectively.
- Olfactory Receptors: Mosquitoes have specialized olfactory receptors located on their antennae and mouthparts. These receptors allow them to detect chemical cues in the environment, including scents emitted by humans, animals, and plants.
- Carbon Dioxide Detection: One of the most powerful cues for mosquitoes is carbon dioxide (CO2). They can detect even small concentrations of CO2, which is why they are highly attracted to the breath of humans and animals. This ability helps them locate potential hosts for blood meals.
- Chemical Signaling: Mosquitoes use chemical signals, known as semiochemicals, to communicate with each other and navigate their surroundings. These semiochemicals include pheromones, which play a role in mating behavior, and kairomones, which help mosquitoes locate hosts for feeding.
- Host Odors: Mosquitoes are attracted to a range of host odors, including lactic acid, ammonia, and various volatile compounds present in human sweat and body odor. These odors act as cues that lead mosquitoes to their preferred hosts.
- Feeding Preferences: Different mosquito species have varying feeding preferences based on the odors they detect. For example, some species are more attracted to humans, while others prefer animals like birds or mammals. Understanding the specific preferences of local mosquito species can aid in targeted repellent strategies.
- Environmental Cues: In addition to host odors, mosquitoes also respond to environmental cues such as temperature, humidity, and light. These factors influence their activity levels and breeding behaviors.
Do Different People Smell Different To Mosquitoes?
Yes, mosquitoes do tend to prefer certain people's smells over others. Several factors contribute to this preference, including genetics, body chemistry, and environmental cues. Here are some key points to consider regarding mosquitoes' preferences for certain people's smells:
- Body Odor: Mosquitoes are attracted to the scent of certain compounds found in human sweat and body odor. These compounds include lactic acid, ammonia, and other volatile substances. Individuals who produce higher levels of these compounds may be more attractive to mosquitoes.
- Carbon Dioxide Emission: Mosquitoes are highly sensitive to carbon dioxide (CO2) emissions, which humans exhale as part of the respiratory process. People who exhale higher concentrations of CO2, such as those engaging in physical activity or individuals with higher metabolic rates, may attract more mosquitoes.
- Skin Microbiome: The microbial community present on an individual's skin can influence their attractiveness to mosquitoes. Some studies suggest that certain types of bacteria on the skin may produce odors that mosquitoes find appealing.
- Genetic Factors: Genetics can play a role in determining a person's attractiveness to mosquitoes. Certain genetic markers may make individuals more or less susceptible to mosquito bites.
- Pregnancy: Pregnant women tend to attract more mosquitoes due to factors such as increased body heat, CO2 emission, and changes in hormonal levels that affect body odor.
- Blood Type: Some research suggests that mosquitoes may show a preference for certain blood types. Individuals with type O blood, for example, may be more attractive to mosquitoes than those with other blood types.
- Dietary Factors: Consuming certain foods and beverages, such as alcohol and foods with strong odors, can temporarily increase an individual's attractiveness to mosquitoes.
- Clothing Color: Dark-colored clothing may attract more mosquitoes than light-colored clothing. Mosquitoes are visually attracted to dark colors, especially during daylight hours.
It's important to note that mosquito preferences can vary depending on the species of mosquito and environmental factors. Additionally, personal experiences with mosquito bites may differ among individuals, with some people being more sensitive to mosquito bites than others.
What Smells Do Mosquitoes Hate?
Mosquitoes are known to dislike certain smells, and leveraging this knowledge can help homeowners deter these pesky insects from their outdoor spaces. Here are some natural scents that mosquitoes hate:
- Citrus: Mosquitoes have an aversion to citrus scents, including lemon, lime, orange, and grapefruit. The strong, acidic fragrance of citrus fruits can act as a natural repellent.
- Peppermint: The minty scent of peppermint is unpleasant to mosquitoes, making it an effective repellent. Planting peppermint around the yard or using peppermint oil can help keep mosquitoes at bay.
- Lavender: Not only does lavender have a pleasant aroma for humans, but it also repels mosquitoes. Mosquitoes find the scent of lavender oil or dried lavender flowers unappealing.
- Eucalyptus: The refreshing and camphoraceous scent of eucalyptus is disliked by mosquitoes. Eucalyptus oil can be diluted and used as a mosquito-repellent spray.
- Garlic: While humans enjoy the flavor of garlic in cooking, mosquitoes detest its pungent smell. Incorporating garlic into outdoor meals or using garlic-based sprays can repel mosquitoes.
- Cinnamon: The sweet and spicy scent of cinnamon is another mosquito deterrent. Cinnamon sticks or cinnamon oil can be used strategically to create a barrier against mosquitoes.
- Catnip: While beloved by cats, catnip contains a compound called nepetalactone that mosquitoes find repulsive. Planting catnip in your garden can help repel mosquitoes.
- Rosemary: The woody and aromatic scent of rosemary can deter mosquitoes. Planting rosemary bushes or using rosemary oil in outdoor sprays can help keep mosquitoes away.
- Basil: The strong aroma of basil is disliked by mosquitoes. Planting basil plants or using basil essential oil can help repel these insects.
- Tea Tree Oil: The medicinal scent of tea tree oil is effective in repelling mosquitoes. Diluted tea tree oil can be applied to the skin or used in outdoor sprays.
It's important to note that while these smells can help deter mosquitoes, their effectiveness may vary depending on factors such as mosquito species, environmental conditions, and the concentration of the repellent scent. Additionally, some individuals may be sensitive to certain essential oils, so it's advisable to test a small area of skin before widespread application.

Does Smoke Keep Mosquitoes Away?
Yes, smoke can help keep mosquitoes away to some extent. Mosquitoes are sensitive to changes in the air, and smoke can disrupt their ability to detect their hosts (humans and animals) by masking the carbon dioxide and other chemical cues they use to locate targets.
However, it's important to note that while smoke can be a temporary solution for mosquito control, it may not be as effective or long-lasting as other methods like mosquito traps, insect repellents, or treating standing water (where mosquitoes breed) in your surroundings. Smoke may also cause irritation to some individuals, especially those with respiratory issues or sensitivities.
How To Use Smell To Keep Mosquitoes Away
Now that we know which smells attract and repel mosquitoes, let's explore how homeowners in North Carolina can use this knowledge to their advantage.
- Plant Mosquito-Repelling Plants: Incorporate mosquito-repelling plants like citronella, lavender, lemon balm, peppermint, and lemongrass into your landscaping. Not only do these plants emit scents that mosquitoes dislike, but they also add beauty to your outdoor space.
- Use Essential Oils: Create natural repellents using essential oils. Mix oils like citronella, lavender, eucalyptus, and peppermint with a carrier oil like coconut oil and apply it to your skin before heading outdoors.
- Avoid Attractive Scents: During peak mosquito season, minimize the use of scented lotions, perfumes, and candles that may attract mosquitoes.
- CO2 Disruption: Some repellent devices work by emitting CO2 or other compounds that interfere with mosquitoes' ability to detect human breath, reducing their attraction to potential hosts.
- Eliminate Standing Water: Since stagnant water attracts mosquitoes, regularly check your yard for standing water and eliminate sources such as clogged gutters, birdbaths without circulation, and unused containers.
- Strategic Planting: Plant mosquito-repelling herbs and flowers near gathering areas like patios and seating areas. This can create a natural barrier against mosquitoes.
- Use Smoke: Smoke from various sources, such as burning wood, herbs, or certain plants, to be used to create a smoky environment that deters mosquitoes. Additionally, smoke from certain types of repellent coils or citronella candles can also repel mosquitoes due to the specific compounds they release.
