By the way, for wasp and spider stings, I was taught to use cigarette tobacco and spit or water. You sprinkle the tobacco on the bite, wet it, and put a bandaid over it to hold it in place. You will get absolutely no swelling and when you go to take a bath and remove it, you will see not a sign of the bite. I've thought of trying this on mosquito bites on my daughter but being little, she does not notice the bites till it is too late.
