What Attracts Mosquitoes to Humans & Their Homes

Mosquitoes, like most insects, are attracted to things that ensure their survival: food, water, and shelter. Female mosquitoes specifically target host blood as a crucial component for egg development and their overall reproductive process. This means that mosquitoes are primarily drawn to signals indicating the presence of their next meal. These signals can include body heat, carbon dioxide exhaled by humans, and certain scents emitted from skin. Additionally, mosquitoes are attracted to environments that provide optimal conditions for their survival like areas with standing water which is essential for laying eggs. Understanding these attractants can help in taking preventive measures to minimize mosquito presence in and around homes.

Optimal Conditions for Mosquitoes to Thrive

Mosquitoes thrive in warm and humid environments which is why they are most prevalent in warmer climates. They cannot survive in colder temperatures because these climates lead to mosquitoes dying off or becoming dormant during the winter months. Mosquito season typically begins when temperatures start to rise in late spring and ends when they dip in the fall. Even during peak season, mosquitoes may avoid extreme daytime temperatures. They typically prefer to feed at sunrise and sunset, which are colloquially known as mosquito hours, when conditions are optimal. These periods of twilight offer the right balance of warmth and humidity which make it easier for mosquitoes to be active and seek out hosts.

Things That Attract Mosquitoes to Certain People

Mosquitoes use various signals to find their next meal, and certain factors can make some people more attractive to these pests than others. By gaining insights into these attractants, you can implement strategies to minimize your appeal to mosquitoes and reduce bites.

Carbon Dioxide in Your Breath

Mosquitoes have evolved to use the carbon dioxide exhaled by humans and animals as a primary cue to locate their next blood meal. The elevated levels of carbon dioxide released during heavy breathing, particularly during physical activity, make it easier for mosquitoes to home in on their targets. This keen ability to detect carbon dioxide helps mosquitoes zero in on potential hosts from considerable distances, making those who are physically active outdoors particularly susceptible to mosquito bites. 

Sweat Containing Certain Smells and Pheromones

Mosquitoes are highly attracted to the scents produced by human sweat, which include naturally occurring body odors and pheromones. Compounds like lactic acid, ammonia, and urea are found in sweat and serve as powerful attractants for mosquitoes. These olfactory cues help mosquitoes locate their hosts which makes people who are sweating more prone to mosquito bites. This paired with increased CO2 from exhalation during strenuous activity are sure to draw mosquitoes’ attention. Additionally, floral scents from soaps, deodorants, and perfumes can also draw mosquitoes towards humans as these scents often attract male mosquitoes who feed on nectar. 

Body Temperature

These flying insects have evolved highly sensitive thermal detection capabilities which allows them to pinpoint warm blooded prey with remarkable accuracy. They have evolved to detect thermal sensory information which allows them to sense the warmth emitted by humans and animals. This ability to detect body heat makes them particularly effective at finding hosts during hours of waning light, especially when other cues like carbon dioxide and scent are present. As a result, individuals with higher body temperatures or those engaging in physical activities that increase body heat may be more susceptible to mosquito bites.

What You Eat and Drink

What you eat and drink can significantly impact your attractiveness to mosquitoes. Certain foods and beverages can alter your body odor and make you more appealing to these pests. Alcohol, in particular, has been shown to increase your likelihood of being bitten as it can change the scent and composition of your blood. Consuming foods high in salt or potassium have also been shown to affect your body chemistry which draws the attention of more mosquitoes.

Color of Your Clothing

The color of your clothing can have a surprising impact on your attractiveness to mosquitoes. These insects are particularly drawn to bold and dark colors like black, navy blue, and red. Wearing these colors can unintentionally make you a more visible target for mosquitoes. Additionally, thin, tight-fitting clothing offers little protection against their bites. To minimize the risk, it's advisable to wear loose-fitting clothes in lighter shades to help keep mosquitoes at bay.

Pregnant Women

Pregnant women tend to attract mosquitoes more than others, and while the exact reasons are not entirely clear, it is believed to be related to increased body temperature and higher levels of carbon dioxide output. Pregnant women generally have a higher metabolic rate which leads to elevated body warmth and more frequent respiration, both of which are factors that mosquitoes use to locate their hosts. Consequently, these physiological changes make pregnant women more appealing targets for mosquitoes.

Certain Blood Types

Certain blood types are more attractive to mosquitoes which make individuals with these blood types more susceptible to bites. Studies have shown that mosquitoes are particularly drawn to type O blood, making those with this blood type more likely to be targeted by these blood sucking pests. The exact reasons for this preference are not entirely understood, but it is believed that the chemical composition of type O blood may produce scents or signals that are more enticing to mosquitoes.

Microbiomes

The skin's microbiome which consists of a variety of bacteria can influence how attractive a person is to mosquitoes. Research suggests that individuals with a healthy skin microbiome containing specific microbes may be less appealing to mosquitoes. Conversely, those who lack these particular bacteria on their skin tend to attract mosquitoes more easily. This difference in microbial presence can affect the scents and chemical signals emitted by the skin, which mosquitoes use to locate their targets.

What Attracts Mosquitoes to Your Home and Yard?

The primary factors that draw mosquitoes to residential areas are the presence of stagnant water bodies, lush vegetation, and abundant food resources. Standing water found in bird baths, ponds, or even clogged gutters provide a breeding ground for mosquitoes as females lay their eggs in stagnant water. Additionally, mosquitoes seek shelter in shaded areas with dense foliage, which protect them from harsh sunlight and predators. While female mosquitoes are drawn to blood for reproductive purposes, male mosquitoes feed on nectar which makes gardens with flowering plants and fruit trees appealing to them. To deter mosquitoes from your property, it is essential to:

• Identify and address all sources of still water on your property.
• Incorporate mosquito-repellent plants to counterbalance attractive flora.
• Clear away ground clutter and decomposing organic matter that could serve as mosquito resting places.
• Regularly trim vegetation to reduce shaded areas.
• Maintain clean gutters and drainage systems to prevent water accumulation.
• Use insect growth regulators to interrupt the mosquito life cycle.
• Foster habitats for mosquitoes’ natural predators like bats, birds, and fish.

By diligently applying these preventative tactics, you can substantially decrease the probability of mosquitoes establishing a presence in your living space and surrounding outdoor areas.
