I became immune too, as a kid I decided to "make peace" with mosquitos. I stopped caring so much about being bitten, and soon after stopped getting bumps and itchiness. I guess this happened just because I was bitten enough to adapt, but I still wonder if there was some psychological interplay. Sometimes I'll get a minor bump if in another country, must be a response to different proteins in the foreign mozzie saliva.
