Mosquitoes: Why are they attracted to us?

Ever wonder why mosquitoes are attracted to some people when compare to others? Many Jamaicans believed that if your blood is sweet, then mosquitoes will be more inclined to bite you more than others. With us having over 3,000 species of mosquitoes, only three are predominantly responsible for the transmission of diseases. These are the Anopheles, Culex and Aedes and some of the diseases that are transmitted by them are Malaria, Encephalitis and Dengue respectively.

Mosquitoes being so persistent and irritating at times, possesses an uncanny ability to sense our murderous intention and take flight before one of our fatal swats. However, before taking a blood meal, a mosquito would normally probe the surface of the skin, using sensory organs to find the perfect area to strike a blood vessel. It then injects its proboscis in your skin, releasing saliva in your blood vessel to prevent clotting and facilities the free flow blood. This is when its possible for this vector to transmit disease causing microbes in your body.
With that in mind here are a few reasons mosquitoes are more attracted to some people more than others;

High body temperature
Persons with high body temperature will be more likely to be bitten by one of these vectors e.g. pregnant women. Normal areas of our body with high temperature are our foreheads, neck, wrists and elbows. However, a person who has just finish some vigorous activity and is hot will have blood closer to the surface of their skin. As a result, the mosquito will use the heat to determined where blood is closer to the skin.

Carbon Dioxide
Mosquitoes are attracted to carbon dioxide, therefore a person who breathes heavily, will cause the mosquito to hone in on them as it follows the steady flow of the gas. This is why you will hear them buzzing right at your ear line. So, as you exhale carbon dioxide through your nose, it travels at the side of the face along the ear line, where the vector follows the trail.

Sweat
As we indulge in various activities or due to an increase in our body temperature, the body will start to producing sweat to facilities cooling down. When ever we sweat there is an increase in the secretion of lactic acid through our skin. Mosquitoes are attracted to lactic acid and this will make you their prime victim.

Blood Type
According to several prominent Entomologists, mosquitoes are believed to be more attracted to a person with a Type O when compare to a Type A or Type B. it has also been deduced that persons with certain genetic are greater attractant to mosquitoes than others.
In order to protect yourself from mosquito bites, always wear mosquito repellant containing DEET and light coloured clothing to keep cool.
