List of Partners vendors. Are you a magnet for mosquitoes? Understanding what lures the insidious insects can be useful in avoiding them. Zika, West Nile, Malaria, Dengue Do you make mosquitoes swoon? Studies show that around 20 percent of people are especially irresistible. Some of these we can't do much about, but anything to help avoid the pests and reduce the use of dicey chemicals is worth the effort. As mentioned above, mosquitoes actually use their eyes to target victims.
Adult mosquitoes survive on nectar for nourishment, but females rely on the protein in our blood for the production of eggs. Research has found, in fact, that people with Type O blood are found to be almost twice as attractive to mosquitoes than those with Type A blood; Type B people were in the middle.
Mosquitoes can sense carbon dioxide from a significant distance, and they can see human from a distance of meters. Key to designing these is understanding what attracts and repels mosquitoes to certain individuals.
This opens the door to new tools or strategies for malaria vector control and surveillance such as chemical lures and traps. Our research group at the University of Pretoria is working on a project that seeks to answer the question: why do mosquitoes prefer certain individuals above others?
We were able to detect chemical differences between the two groups. Our findings open two possible lines of inquiry. Firstly, chemical compounds closely associated with mosquito attractive individuals could potentially be used in chemical lures to trap mosquitoes outdoors. And secondly, compounds closely related to individuals being unattractive to mosquitoes could be developed into new repellents.
Female mosquitoes need a blood meal for their eggs to develop. First, the female mosquito must find its host.
It can be quite selective. For example the Culex quinquefasciatus mosquito feeds exclusively on birds. Mosquitoes find themselves in complex environments filled with many different cues or stimuli. For them, the body temperature is higher. Those who have genetic prebondance to the same.
If you qualify for any of these mosquito-attracting attributes, stay safe. Always seek the guidance of your doctor or other qualified health professional for any questions you may have regarding your health or a medical condition.

Mosquitoes use CO2 as their primary means of identifying bite targets, Day says. Also, drinking alcohol or physically exerting yourself raises your metabolic rate—and also your appeal to winged biters, he adds. While CO2 detection is the primary technique mosquitoes and other blood-sucking bugs use to spot hosts, they also rely on secondary cues to differentiate you from cars, decaying trees, and other CO2-producing objects.
And you can control some of those secondary cues, Day says. For example: Dark clothing is more attractive to mosquitoes than light oufits.
