Wasp and ant venoms also include hyaluronidase, an enzyme that breaks down the "glue" that binds cells together. That allows the venom to penetrate through the tissue even if it doesn't get into a blood vessel. Yellowjacket venom also has histamine, so that the venom itself induces an inflammatory response, but fire ant venom doesn't (though histamine gets released by your own body as a result of being stung).
