Experts say this could be the beginning of what could be a very busy bee season.
It was a pretty incredible scene as the Royals-Angels game had just started when the bees swarmed the field and ultimately caused two delays.

"There is a movement of bees in the left field area," said an announcer.
Thousands of bees moved in, forcing players to run for cover. The bees eventually took up residence in an unlikely spot.
"They have found a spot on the microphone," he said.
"Before you knew it they were all gathered up on the boundary mic here on the backstop on the fence," said General Manager Jerry Hall.
Hall, who manages the field, said they've never seen anything like it. The safety of the 7,200 people at the game were his number one priority.
"We moved some people from the seating area, obviously we didn't know if anyone was allergic or there was any issues," he said.
The game was delayed a second time and a pest control company was called to remove the unwanted guests before the game could resume.
Curtis Whalen with Blue Sky Pest Control said this is when they start to get a lot of bee calls. The warmer temperatures and the wet fall and winter we've had mean more bees.
"We're actually forecasting an above average amount of bee activity this year," said Whalen.
As far as where all the bees came from, that is a mystery.
"It's spring time in Arizona, so that's what we get," he said.
Luckily nobody was stung by the bees. Still no word on where they all came from, or why they decided to gather on the microphone.
