Unless you are absolutely overwhelmed with it, hand-pulling works, obviously.
Even if you only spend 15 minutes a day, little-by-little you will get rid of most of it and won't be using insecticides that harm the environment.
I'm sure you are aware that it will always be present because of birds dropping seeds, the wind, and mostly -- your or your yard man's lawn mower which has all kinds of nasty stuff harbored on the underside of the mower.
