I don't mean to be a crybaby (after my yellowjacket sting) but I now have a chigger bite!
(some say amputation helps alleviate the itch -- for a while). Chiggers live on tall grass and low shrubbery limbs, so that's the place to spray insecticide. And, opposite to everything you've always heard, they drop off after feeding, so applying nail polish to the bite is ineffective. I apply very hot water and that seems to make the itch go away.
