Mosquitoes. Mosquito bites get some relief with heat
There is another sure fire way to instantly stop the itching. As soon as itching starts dampen and fold several times a washcloth. Place it in the microwave as it is quicker or find some other way to heat it. (Tap water is usually not hot enough).
The temperature should be hot but not enough to scald the skin and tolerable. Place the hot washcloth directly over the bite. The person will begin to feel a sharp, burning, and stinging pain exactly where the bite occurred. Keep the washcloth over the bite for about one minute while tolerating the pain.
The mosquito saliva contains protein left inside the bite and the hot temperature neutralizes the protein which causes the sharp pain. After removing the washcloth, there will be no itching sensation. It works each time.
