When relaxing in the country or fishing, especially in the late afternoon when the sun disappears behind the horizon, the most annoying thing is the buzzing of mosquito wings and their painful bites. If you do not anticipate this problem in advance and do not use protective measures such as repellents or insect killers, your holiday can be ruined.

How does a mosquito bite?

Mosquitoes have an amazing ability to detect potential victims for blood sampling. They focus on the carbon dioxide emitted by a person when breathing, as well as the heat emitted by the body. At the same time, a cloud of noise or loud music can hide the squeak of a mosquito and the moment of landing. With its sharp jaws, the mosquito makes an imperceptible incision in the skin and injects saliva containing analgesic and anticoagulant substances into the wound. The insect then begins to suck blood through its proboscis. It is important to remember that children, due to their thin skin, are more susceptible to mosquito attacks, so appropriate precautions must be taken. If an allergic reaction or swelling occurs at the site of the bite, it is important to seek medical attention.

Mosquito bite process

When making an “injection,” the mosquito carefully avoids the nerves so as not to cause pain during the blood-sucking process. To hold the area of ​​skin, the mosquito uses its mandibles, and the upper lip, called the lambrum, makes a precise puncture into the vessel through which the blood pulsates. It is then directed into the mosquito's stomach through a sting created by the hypopharynx, which is similar to the tongue. While the body begins to fight blood loss by activating the clotting system, the mosquito counters this by injecting mosquito saliva into the puncture with chemical coagulants that prevent blood clotting. The immune system begins a “fight” with the foreign protein compound in the bite area, which leads to itching and redness over the next few days. This all happens in just a few seconds, although the process will take much longer to fully explain.

Who is most often bitten by mosquitoes?

Mosquitoes that pester you in the summer can not only cause discomfort, but also pose a danger. Although dangerous insects are rare in our area, it is important to know when a common mosquito bite can cause serious harm. To avoid attacks from bloodsuckers, it is important to understand who they choose as their victim. Scientists believe that mosquitoes are guided by heat and carbon dioxide, using smell and vision to identify their target. They prefer pregnant women and obese people due to the release of more heat and carbon dioxide, and may also be attracted to certain chemicals such as lactic acid and ammonia released in sweat. There is also a version that the first blood type is attractive to mosquitoes, and drinking alcohol, especially beer, can increase the risk of being bitten. However, people taking vitamin B are less interested in these insects.

What to do after a mosquito bite

After a mosquito bite, there is usually a local reaction such as redness, swelling, itching or even pain. In this case, the reaction can be individual and depend on the location of the bite. In the case of children, insect bites can cause discomfort, and if a severe allergic reaction occurs, especially in the mouth or throat, a doctor should be consulted. Swelling of the face, lips, tongue, or difficulty breathing requires immediate medical attention as an anaphylactic reaction can be dangerous. You can relieve pain and reduce swelling at home by applying a cold compress. If a local reaction persists for a long time or worsens, you should consult a doctor, especially if you have a fever or suspect an infection.
