The feisty bees disrupted play again in the fourth inning before they were removed by exterminators.
The Angels had just taken the field when the Bees descended on the outfield and players were ordered to their dugouts. Royals and Angels players converged near the Royals' third base dugout.
Many fans left their seats down the first base line and went up to the higher concourse. As the bees moved toward the backstop, those fans behind the plate left their seats.
When play resumed, the bees settled together on a microphone attached to the backstop netting, about 20 feet to the left of Angels manager Mike Scioscia, who sits outside the first base dugout.
