WASHINGTON - (WUSA) -- Nearly four months after beginning their well-publicized occupation of McPherson Square and Freedom Plaza, protesters at both locations have apparently worn out their welcome with the National Park Service.

After numerous complaints about trash and rat problems, especially at McPherson Square, including a formal complaint from DC Mayor Vincent Gray, the Park Service now says that starting at noon tomorrow U.S. Park Police will begin enforcing the ban on camping and the use of temporary structures for camping in McPherson Square and Freedom Plaza.  The Park Service says anybody in violation of the ban could be arrested and have their camping gear confiscated. 

Protesters we spoke with at McPherson Square said even if they're no longer allowed to camp out here, the Occupy DC movement will continue.
