Why Does Our Skin Itch When A Mosquito Bites

When mosquitoes break our skin to inject the suckers and draw out blood, they leave behind their saliva in our body. This saliva contains elements like amino acids and anticoagulants, which our body treats as foreign substances.

Because of a foreign substance’s presence, the body’s immune system gets activated, and a compound called histamine is released. Histamine helps white blood cells to rush to the bitten area and start working on recovery.

The presence of histamine and white blood cells around the affected area causes the rash-like response, resulting in redness, swelling, and the corresponding inflammation and itching.


How much a person’s body will react to a mosquito bite varies from one to another. Some people never have any reaction to mosquito bites except an initial itching in the area, especially if they live in more mosquito-infested regions. Their bodies become tolerant to mosquito bites over time.

On the other hand, others might show consistent symptoms of mosquito bites and even grow to show signs of infection in the bitten area.
