Spotted Spurge

Thanks! Is this a common weed? I've never heard of it before? I always hear about creeping charlie, chickweed, etc.. but I've never heard of spotted spurge.

And aside from pulling it, what's the best/easiest way to kill it? Will the new roundup for northern lawns work?

In late July and August, it's very common. It's easiest to just pull it if it isn't everywhere - many herbicides can't be used when temps are above 80-85, and they're always up there in July/August.
