A wasp sting is formic acid I think you're confusing ants with bees and wasps. Ant stings are formic acid (the very word "formic" being derived from the Latin for "ant"); and they may be bites rather than proper stings. Formic acid is a very simple compound, chemically speaking. Bee (and afaik wasp) stings contain mixtures of kinins, fairly short-chain proteins with powerful physiological effects. There may be other ingredients as well. Kinins cause intense pain, swelling, and so on. That they're proteins explains why some people become allergic, as allergies are almost entirely in response to proteins, not simple substances like formic acid.
