What Attracts Mosquitoes to Traps: Understanding Their Lure

Mosquito traps are valuable tools in reducing mosquito populations and creating a more comfortable outdoor environment. But what exactly attracts mosquitoes to traps? In this article, we will explore the factors that attract mosquitoes to traps, helping you understand their lure and enhance the effectiveness of your mosquito trapping efforts.

Carbon Dioxide (CO2)

Mosquitoes are highly sensitive to carbon dioxide, which is a primary attractant for them. Mosquito traps often emit CO2, mimicking the breath of humans and other animals. The release of CO2 draws mosquitoes towards the trap, as they associate it with a potential blood meal.

Heat and Body Heat

Mosquitoes are also attracted to heat, as they use thermal cues to locate their hosts. Many traps incorporate heat sources or emit warmth to simulate the presence of a warm-blooded host. The combination of heat and CO2 makes the trap more enticing to mosquitoes.

Movement and Visual Cues

Mosquitoes are responsive to movement and visual stimuli. Some traps utilize moving parts, such as fans or vibrating elements, to simulate the motion of a living creature. Additionally, traps with contrasting colors or patterns can attract mosquitoes, as they are attracted to visual stimuli that indicate a potential feeding opportunity.

Chemical Attractants

In addition to CO2, certain chemical attractants play a role in attracting mosquitoes to traps. These chemicals include lactic acid, octanol, and various mosquito attractant blends. These attractants mimic the scent of human sweat and other bodily secretions, which mosquitoes associate with a blood source.

Light and Ultraviolet (UV) Light

While mosquitoes are not primarily attracted to light, some traps incorporate UV light sources. Mosquitoes may be drawn to these traps because they are more active during the evening and night when light sources are less prevalent. However, light alone may not be sufficient to attract mosquitoes effectively


Understanding what attracts mosquitoes to traps is key to maximizing the effectiveness of mosquito trapping efforts. By incorporating factors such as carbon dioxide, heat, movement, chemical attractants, and UV light, traps can significantly enhance their attractiveness to mosquitoes. It’s important to consider these elements when selecting or designing a mosquito trap for optimal mosquito control.

Remember that the effectiveness of traps may vary based on mosquito species, environmental conditions, and trap design. To achieve the best results, consider combining trap usage with other mosquito control methods such as eliminating breeding sites, using repellents, and maintaining a clean and tidy outdoor environment.

By leveraging the knowledge of mosquito attractants, you can improve the performance of your mosquito traps and enjoy a more mosquito-free outdoor space.
