Usually, having lots of weeds of any type is symptom of a lawn that is
not thick and dense. If it is, it will block out most weeds on it's
own. Still you will always have some, but they should be easily
treated with some minimal herbicide applied via a tank sprayer. That
minimizes the herbicide, which is better for the environment.

I'd start by analyzing what kind of grass you have and what shape it's
in. Aerating, overseeding, proper fertilization, PH, etc could be
appropriate steps to not only help keep the weeds out, but make it
look better too.
