The event took place at the South Portico, which was lit orange for the occasion, the White House said in a release.
The decorations included 185 carved pumpkins and topiaries of the first dogs dressed up in costume -- pipecleaner "Bo" as a pirate and ribbon "Sunny" as a sunflower.
Chicago's Black Bear Combo brass band provided the Halloween music while in-costume actors and volunteers spooked the estimated 5,000 children.
Boxes of White House M&Ms, jelly beans, sweet dough butter cookies and dried fruit were provided as treats.
