Have you ever noticed that mosquitoes seem to bite some people more than others? You might be sitting outside with friends, yet one person ends up covered in itchy bites while everyone else seems fine.
It may feel like bad luck, but research shows mosquitoes use smell, heat, and even colour to find people. Some everyday factors can make certain people easier for mosquitoes to detect.
Here are some surprising things that may attract mosquitoes.
- The Carbon Dioxide You Breathe Out
Mosquitoes are very sensitive to carbon dioxide, the gas we release when we breathe. They can detect it from a distance and use it to locate potential hosts.
- Body Heat
Mosquitoes can sense body heat, which helps them find where to land and bite. People with higher body temperatures may attract more attention.
- Sweat
Sweat contains chemicals such as lactic acid and ammonia that mosquitoes can detect. After exercise or spending time outdoors, these scents may make a person easier for mosquitoes to find.
- Your Natural Body Odour
The bacteria living on your skin break down sweat and produce different scents. These natural body odours can influence how attractive a person is to mosquitoes.
- Genetics
Research suggests that genetics may also play a role. Studies involving twins have found that identical twins often attract mosquitoes at similar rates, suggesting that inherited traits may influence mosquito attraction.
- Pregnancy
Studies show that pregnant women may attract more mosquitoes. This may be because pregnancy can increase body temperature and carbon dioxide production.
- Certain Colours
Mosquitoes also use vision. Research suggests they are drawn to colours such as red, orange, black and cyan (a blue-green shade), which may stand out more clearly in the environment.
- Floral Scents
Perfumes, lotions, or soaps with floral fragrances may attract mosquitoes because these scents resemble flowers that mosquitoes naturally feed on.
Mosquito bites are often just an itchy nuisance, but in regions where mosquito-borne diseases occur, understanding what attracts mosquitoes can help people be more aware of when and where bites are most likely to happen.
