Why do mosquito bites itch?
When mosquitoes bite humans, they inject an enzyme called "hyaluronidase" into the skin. This enzyme breaks down hyaluronic acid, a substance found in the skin, so that the mosquito can access the blood more easily. The body's reaction to this enzyme is what causes itching and inflammation in the bite area. The body responds by sending histamine to the bite area, which increases blood flow, an anticoagulant that thins the blood, and mediators, which cause itching and redness of the skin.
This irritation can cause discomfort and itching that lasts for hours to days after a mosquito bite, depending on the individual and how the body reacts to the mosquito's toxins. The presence of anticoagulants in mosquito saliva is part of the answer to why their bites itch.

Applying ice to a mosquito bite can numb the area, reduce swelling and itching, because the sudden cold causes blood vessels to constrict, reducing inflammation. According to the American Academy of Dermatology, applying ice or a cold towel to the affected area for 5 to 10 minutes can relieve itching and swelling.
Apple cider vinegar
