hydrocortisone cream applied after wiping with alcohol works for me, a few summers ago was on the TX coast fishing and the mosquitos were swarming, have never seen anything like it, on 1 leg i had over 150 bites (and we werent out long.....) i stopped counting at 150, that cant be good for ya let me tell ya. but the hydro cream stopped the itching pretty well once i got some anyway.
