Cilantro and Gnats

Cilantro and Gnats

I have an (now indoor, just moved from outdoor, and potted) cilantro plant, that all of a sudden (within a day) has little flying bugs, like gnats, swarming all around it. I dont know where they came from or how to rid my plant of them. Do they hurt they plant? I would like to get rid of them, but if they are not harmful then im less concerened! Also how do you know what Zone you live in? Im in the bay area of Ca? What do they stand for? :) Thanks for your help! +panda+
