When a mosquito bites you, it pierces the skin using a special mouthpart (proboscis) to suck up blood. As the mosquito is feeding, it injects saliva into your skin. Your body reacts to the saliva resulting in a bump and itching. Some people have only a mild reaction to a bite or bites.
Why should you not scratch mosquito bites?

How long until mosquito bites stop itching?
Most people have a minimal response and notice small, pink, itchy bumps within 20 minutes of the bite. The itching usually peaks within 24-48 hours. The bite generally fades over three-to-four days. It may take up to a week to completely heal.
Why does it feel good to itch a mosquito bite?
Here’s how it works: when something bothers the skin, like a mosquito bite, cells release a chemical, usually histamine. That release provokes the nociceptors in the skin to send a message to the spine, which then relays the message through a bundle of nerves called the spinothalamic tract up to the brain.
What is inside a mosquito bite?
Histamine is a chemical created by your immune system. Your body releases histamine after it encounters an allergen. Histamine is what makes mosquito bites itch. You can take an antihistamine as a pill, or you can apply it directly to your mosquito bite as a cream or ointment.
What happens if you squeeze a mosquito bite?
After a mosquito bite, a tight blister can form over the puncture wound made by the insect and tension in the skin causes the pain. Scratching will only distress the traumatised skin even more. Some time ago, I experimented bursting one of a pair of mosquito bite blisters and leaving the other to heal naturally.
What would happen if mosquitoes went extinct?
Without mosquitoes, thousands of plant species would lose a group of pollinators. Adults depend on nectar for energy (only females of some species need a meal of blood to get the proteins necessary to lay eggs). Yet McAllister says that their pollination isn’t crucial for crops on which humans depend.
How many times can a mosquito bite you?
There is no limit to the number of mosquito bites one of the insects can inflict. A female mosquito will continue to bite and feed on blood until she is full. After they have consumed enough blood, the mosquito will rest for a couple of days (usually between two to three days) before laying her eggs.

No. The greater the time the mosquito is allowed to feed, the more saliva she’ll inject into the skin. Allowing her to feed longer will increase your reaction to the saliva and enhance the risk of infection from mosquito-borne pathogens.
