  • Excessive scratching of the site affected by a mosquito bite rash can result in tearing of the skin and formation of small wounds, which are vulnerable to bacterial and other pathogenic infections.
  • Increased incidence of mosquito bite rashes can increase the immunity to the adverse effects of a mosquito bite, thereby causing milder symptoms with subsequent episodes. However, children are at greater susceptibility to allergic reactions to a mosquito bite rash, as their immune systems are still in developmental stages.
  • Most of the signs accompanying a mosquito bite rash disappear in a few hours, or at the most in one day.
  • Mosquitoes have a powerful sense of smell and are attracted to the chemicals that we release from our body.  One of these chemicals is carbon-dioxide, women and larger people tend to release them in more quantities, in terms of respiration. The more of carbon-dioxide being breathed out, the easier it is for mosquitoes follow you and bite you.


  • Mosquitoes have inhabited the planet for approximately 30 million years. They are able to detect their prey with the aid of sensors capable of identifying lactic acid, carbon dioxide and other chemicals from even one hundred feet away. It is a known fact that humans and other animals give out the gases during the normal breathing process. They then bite the victims and cause a mosquito bite rash.
  • Mosquitoes are also drawn to substances present in sweat. This is believed to be one of the reasons why individuals who sweat heavily tend to get bitten by mosquitoes more often, as compared to those who sweat less. Mosquitoes are also equipped with other sensors that allow then to detect organisms in motion. Lastly, they posses heat sensors that ensure the detection of warm blooded organisms in the nearby areas.
  • The female mosquito uses a sharp, razor-thin organ called the proboscis to puncture the skin and suck the blood. Hence, most sufferers are usually unaware of the insertion of the proboscis into the body. The saliva of the mosquitoes has anti-blood clotting properties which facilitate easy suction of blood.
  • A tiny gash appears at the site of the mosquito bite, after the insect has had its fill. Such a wound contains some saliva. It is prone to swelling and with the passage of time, forms into a mosquito bite rash or a welt. The proteins occurring in the saliva activate an immune response which leads to itchiness. The mosquito bite rash and swelling gradually disappear, but the itching continues till the salvia proteins are fully wiped out by the immune system
