The Science of Mosquito Repellents

What Attracts Mosquitoes to Humans?

As perplexing as it may seem, mosquitoes are drawn to humans by a combination of factors, including body odor, heat, and carbon dioxide. These insects are remarkably proficient at detecting human scent, often using the carbon dioxide we exhale as a primary cue for locating their next meal. Additionally, body heat and sweat can also attract mosquitoes, making individuals more susceptible to bites.

Body Odor: Mosquitoes are attracted to the various scents emitted by the human body, which can differ from person to person due to genetic and environmental factors.
Carbon Dioxide: The carbon dioxide we exhale acts as a powerful signal for mosquitoes, enabling them to locate their human hosts from a distance.
Body Heat: The warmth emitted by the human body is another factor that draws mosquitoes in, as they are able to detect these subtle temperature variations.
Sweat: The compounds present in human sweat, such as lactic acid and ammonia, serve as attractants for mosquitoes, increasing the likelihood of bites.

Further research has revealed the intricate mechanisms behind mosquito attraction to humans. One key element is the human skin microbiota, which produces a unique blend of volatile compounds that contribute to an individual’s attractiveness to mosquitoes. This complex interplay between human biology and mosquito behavior underscores the multifaceted nature of mosquito attraction.

How Do Mosquito Repellents Work?

Mosquito repellents function by creating a barrier between a person’s skin and the mosquitoes, making the user less appealing to the insects. The active ingredients in repellents interfere with the mosquito’s ability to detect the human scent, thus decreasing the likelihood of being bitten. This protective shield provides individuals with a layer of defense against mosquito-borne diseases, offering peace of mind during outdoor activities.
