During the next 4 days, firefighting efforts continued to slowly extinguish the Bully Fire, until full containment of the perimeter was achieved on July 26, at 8:00 PM PDT. Fire patrols lingered for the next couple of days to work on extinguishing the blaze, and on July 28, the Bully Fire was reported to be 100% controlled.
