When a mosquito bites you and takes the blood, it replaces it with a serum...here , this will be better explained by a pro...
When the mosquito stabs her needle-like mouthparts through the skin of her victim, she injects her saliva -- teeming with digestive enzymes and anticoagulants. The first time a person is bitten, there is no reaction. With subsequent bites, the person becomes sensitized to the foreign proteins, and small, itchy, red bumps appear about 24 hours later. This is the most common reaction in young children. After many more bites, a pale, swollen hive, or wheal, begins to appear within minutes after a bite -- followed by the red bump 24 hours later. This is the most common reaction in older children and adolescents.
With repeated mosquito bites, some people begin to become insensitive again, much as if they had allergy shots. Some older children and adults get no reaction to mosquito bites (unless they go for a long time without being bitten -- then the process can start again). Other people become increasingly allergic with repeated stings. They can develop blistering, bruised, large inflammatory reactions. For these people, avoiding being bitten is a particularly good idea.

when mosquitos bite, they leave a little bit of their saliva in the bloodstream and your body sees the saliva as a foreign object. Therefore it pushes it out, first of all causing the bump, and as you itch it you peel away the skin allowing the saliva to leave the body, however, if you let it go without itching your immune system will eventually get rid of it anyway.

The bug uses a toxin that acts as a anesthetic which numbs your skin long enough for him to drink. Your skin has a reaction to the toxin, which is why it itches.

Even though you rarely get sick, its actually a venom when a misquito bites you. That's why the bites get red and itchy.

The chemicals necessary to keep the blood flowing causes the itching.
