Why Do Mosquitoes Bite Some People More Than Others?

Mosquitoes Bite

Do mosquitoes seem to bite you more than others? If you’ve ever wondered why, science may have some answers. Research suggests that factors like body temperature, scent, and even the colour of your clothes can make you more appealing to these blood-sucking insects. As the monsoon season makes it more conducive for these mosquitoes to breed, understanding these factors can help you reduce the chances of getting bitten.

When you breathe, you give out carbon dioxide. Mosquitoes can detect changes in carbon dioxide levels in the environment. Research shows that different mosquito species respond uniquely to CO2 spikes, signalling them to locate a potential host. Any increase in carbon dioxide can act like a beacon for mosquitoes.

Mosquitoes are drawn to specific compounds present on human skin and in sweat, which produce distinct odours that attract them. Previous studies have identified lactic acid and ammonia as key culprits. A 2015 study revealed that mosquitoes were particularly attracted to the odors of identical twins. Additionally, skin bacteria play a crucial role in body odour. A seperate study in 2011 found that people with a more diverse array of skin microbes were less appealing to mosquitoes.

Interestingly, mosquitoes are more attracted to darker colours, particularly black. Although the exact reason behind this remains unclear.

Our bodies emit heat and water vapour, which mosquitoes can detect. Research indicates that mosquitoes are drawn to heat sources at optimal temperatures. Other animals have body temperatures that are less appealing to mosquitoes, making humans more desirable hosts for the pests. 

Mosquitoes may even develop preferences based on their experiences. They can associate certain scents with hosts that have provided them with high-quality blood meals.

A small study in 2002 found that people who consumed beer were more attractive to mosquitoes compared to those who didn’t drink. 

Studies also suggest that mosquitoes are more attracted to pregnant women, likely due to their higher body temperatures and increased carbon dioxide exhalation.
