Because before the mosquito sucks blood, in order not to be noticed, it will first inject a venom into the person's **, which will paralyze the person's nerves so that the mosquito will not be detected in the process of sucking blood. But then it gets bagged and itchy.
The venom of mosquitoes is acidic, so wash it with something alkaline and it doesn't feel too itchy. For example, soapy water.
There is also a saying that there is an acid-base balance in human blood, and human blood is weakly alkaline, and mosquitoes must first inject a certain amount of formic acid into the subcutaneous blood vessels when they bite people to suck blood. This kind of substance that prevents blood clotting, which contains protein, it is a foreign body to the human body, destroys the acid-base balance of the human body's blood, thereby changing the viscosity of the blood here, the microcirculation of the blood is destroyed, causing a small range of blood coagulation, causing people's own immune response, some people react strongly, it will be red and swollen into a small packet, and will feel itchy; If someone reacts weakly, it is not obvious. After a few days, when the body's blood reaches acid-base balance again, the symptoms will disappear.

It's normal. Mosquitoes will inject some anticoagulant wild substances into the human body when biting, and if these anticoagulant substances are more sensitive than those of the pickpocket, there will be a relatively large rash and itching.

Therefore, you don't feel pain or itch after being bitten by a mosquito, but you just have a red spot, just because you are insensitive.

Regarding biting pain, mosquito bites belong to the "pain que" in the medical pain level, which is the lowest pain, and it is good to be able to feel it. > almost everyone has the unpleasant experience of being "bitten" by mosquitoes, in fact, it should be said that they have been "stung" by mosquitoes. Mosquitoes can't open their mouths, so they won't bite on the **, it actually uses 6 needle-like structures to pierce people**, these short needles are the center of the mosquito's edible mouthparts.
These short needles suck human blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting, so that it can feast peacefully. When the mosquitoes are full of food and drink and float away, all they leave behind is an itchy lump. >, however, the itchy sensation is not caused by a short needle pricking or chemicals in the saliva.
We feel itchy because the body's immune system releases a protein called histamine to fight foreign substances, and this immune response triggers an allergic reaction at the bite site. Histamine causes swelling of the tissues around the bite when blood flows to the bite site to speed up tissue recovery, and the intensity of this allergic reaction varies from person to person, with some people having a more severe allergic reaction to a mosquito bite. > only female mosquitoes bite mammals because they have to suck blood every three or four days to get the protein they need to make eggs; Male mosquitoes mainly feed on nectar, while female mosquitoes use animal body heat and physiological changes to search for targets, which may be why human ankles and feet are more commonly bitten by mosquitoes, because the blood vessels in these parts are closer to the body surface, so more body heat is released.

Secondly, the calm and stale water is a place for mosquitoes to breed, and thirdly, the number of natural enemies of mosquitoes cannot eliminate more mosquitoes, and the ecology is unbalanced. >>>More
