AfterBite is great stuff. Corticosteroid cream should also do the trick for a little itch. Lanacane with 20% benzocaine is very powerful, and you can buy it over-the-counter. If you are suffering badly, go to a dermatologist and request a prescription-strength topical steroid like Triamcinolone (2nd level) or Clobetasol (most powerful topical steroid they make).
