If you have an average size suburban lawn, I'd pick the flowers to keep them from going to seed and spot treat with Weed-B-Gone. If your neighbors don't use herbicides to control dandelions, you're job of spot, stalk, and treat will never end. One of my neighbors has small children and a dog, so he doesn't use herbicides on his lawn, nor does he use a dandelion fork to remove them, so his lawn is more weed than grass.
