No-see-ums, also known as biting midges, are tiny, blood-sucking insects that can be a real nuisance. They are attracted to carbon dioxide, lactic acid, and octenol, which are all produced by humans and animals. They are also drawn to light and heat, which means electricity may attract them. In addition, they are drawn to water, and females lay their eggs on standing water surfaces. To avoid being bitten, it is recommended to wear long sleeves and pants and use insect repellents.

What You'll Learn
No-see-ums are attracted to carbon dioxide, lactic acid, and octenol
No-see-ums, also known as biting midges, are tiny insects that pack a powerful bite. They are so minuscule that they can attack without being seen, leaving painful and itchy welts on the skin. Female no-see-ums bite to obtain a blood meal, which is necessary for egg development.
No-see-ums are attracted to several factors, including carbon dioxide, lactic acid, and octenol. Carbon dioxide is a major attractant, as no-see-ums can detect and are attracted to the carbon dioxide exhaled by humans and animals. This helps them locate a potential blood meal. As a result, they become more active during dawn and dusk when carbon dioxide levels are typically higher.
Lactic acid is another significant attractant for no-see-ums. It is produced by the human body during physical activity, and they can detect it from a distance. Higher levels of lactic acid are produced during exercise, making individuals more attractive to these pests. Octenol is also an important attractant, found in human breath and sweat, as well as in the urine and sweat of cows and horses, making these animals more susceptible to no-see-um bites.
In addition to these primary attractants, no-see-ums are also drawn to body heat and body odour, including the odour from lactic acid. They thrive in warm, humid conditions and are often found near bodies of water, as they require moisture for breeding and egg-laying. No-see-ums are also attracted to light and dark-colored clothing, as darker colours absorb more heat.

They are drawn to body heat and body odour
No-see-ums, also known as biting midges, are tiny blood-sucking insects that are a common pest. They are attracted to carbon dioxide, which humans exhale, and are also drawn to body heat and body odour. They are prevalent in warm, humid areas, particularly near water, and are most active at dawn and dusk.
No-see-ums are drawn to body heat, sensing and gravitating towards individuals emitting body heat. Dark-coloured clothing absorbs more heat, making individuals who wear such attire more appealing to no-see-ums.
Body odour is another attractant for no-see-ums. They are attracted to the odours emitted by the body, including those from lactic acid and perspiration. Individuals who have been exercising and have elevated body temperatures and increased perspiration may be more appealing to no-see-ums due to these odours.
In addition to body odour, no-see-ums are attracted to certain floral scents. Heavily scented lotions, perfumes, or shampoos can attract no-see-ums when used in areas prone to these pests. It is recommended to avoid wearing perfumes and scented products outdoors during the season when no-see-ums are most active.
While no-see-ums are drawn to body heat and body odour, there are ways to deter them. No-see-ums dislike certain essential oils, such as camphor, eucalyptus, mint, and lemon. These oils can be used in natural repellent mixtures applied to the body or diffused in the home to keep no-see-ums away. Additionally, fans can be placed near patios and porches to create a barrier against no-see-ums, as they struggle to fly against the airflow.

They prefer dark clothing, which absorbs more heat
No-see-ums, also known as biting midges, are tiny, blood-sucking insects that are prevalent in warm, humid climates and are particularly active during dawn and dusk. They are attracted to areas with standing water, such as ponds, marshes, and damp soil, where they lay their eggs.
One of the main ways to avoid no-see-ums is to avoid wearing dark clothing. Dark-colored clothing absorbs more heat, making individuals wearing such attire more appealing to these heat-seeking bugs. No-see-ums are attracted to body heat, and the darker your clothes, the more heat they will absorb, making you a more appealing target for these pests.
To avoid becoming a target for no-see-ums, it is recommended to wear light-colored, loose-fitting clothing. This type of clothing will help minimize your attractiveness to these insects. Additionally, wearing long sleeves and long pants can also help reduce your risk of being bitten, as it limits the amount of exposed skin.
While avoiding dark clothing can help, it is important to note that no-see-ums are also attracted to other factors, such as carbon dioxide, body heat, body odor, and floral scents. They are also drawn to light, so if you are spending time outdoors in the evening, it is advisable to keep lighting to a minimum.
In addition to avoiding dark clothing, there are other measures you can take to protect yourself from no-see-ums. These include using insect repellents, fans, and essential oils with scents such as camphor, eucalyptus, lemon, and mint, which are unappealing to these insects.

They are attracted to light, including ultraviolet light
No-see-ums, also known as biting midges, are tiny blood-sucking insects that are attracted to light. They are drawn to light sources such as ultraviolet light and electrical lighting. Bug zappers, for instance, use ultraviolet light to attract and kill no-see-ums. No-see-ums are also attracted to electrical lighting in yards, which can draw them closer to humans and other potential hosts.
To prevent attracting no-see-ums, it is recommended to turn off outdoor lighting when not in use. No-see-ums are also attracted to light-coloured clothing, as darker colours absorb more heat and make individuals wearing such attire more appealing to these heat-seeking insects.
In addition to light, no-see-ums are attracted to warm and humid conditions, particularly near bodies of water. They are drawn to areas with high moisture content, such as marshes, damp soil, and standing water, where female no-see-ums lay their eggs. The larvae then develop in these moist environments, making no-see-ums more prevalent in coastal regions.
No-see-ums are also attracted to carbon dioxide, which humans and animals exhale. Higher concentrations of carbon dioxide signal the presence of potential hosts, drawing the insects closer. Body heat and body odour, including lactic acid and octenol, are also attractants for no-see-ums.

They are drawn to water, particularly stagnant water
No-see-ums, also known as biting midges, are tiny insects that are notorious for their painful bites. They are drawn to water, particularly stagnant water, where the females lay their eggs. These eggs hatch, and the larvae develop in moist environments.
No-see-ums are attracted to water sources such as ponds, marshes, and damp soil. They thrive in environments with high moisture content, making them a common pest in coastal regions. The females seek out moist areas to lay their eggs, which then hatch into larvae that thrive in these wet conditions. This preference for water makes it crucial to eliminate potential breeding sites, such as standing water, wet mud, and plant debris, to reduce the presence of no-see-ums.
Additionally, no-see-ums are drawn to the carbon dioxide, lactic acid, and body heat that humans and animals emit. They are adept at detecting the presence of potential hosts, which makes them relentless in seeking blood meals. This attraction to carbon dioxide and body heat, combined with their small size, enables them to easily infiltrate homes and yards, causing discomfort and frustration.
To repel no-see-ums, individuals can take several measures. It is recommended to wear light-colored, loose-fitting clothing to minimise attractiveness to these pests. Long sleeves, pants, and socks can also help reduce skin exposure. Avoiding dark-colored clothing is essential as it absorbs more heat, making individuals more appealing to no-see-ums. Additionally, individuals should refrain from using heavily scented lotions, perfumes, or shampoos when in areas prone to no-see-ums.
The use of insect repellents containing DEET, picaridin, or oil of lemon eucalyptus can effectively deter no-see-ums. Essential oils such as camphor, eucalyptus, lemon, and mint are also unappealing to them and can be used in natural repellent mixtures for the skin or diffused indoors. Fans are another useful tool, as no-see-ums prefer still conditions and struggle to fly against airflow. Placing fans near outdoor seating areas can create a barrier to protect against their bites.
