CHARLOTTE, N.C. -- Bees are more active around this time of the year, as flowers begin to bloom in the Carolinas.

"I just killed a bunch," says resident Michael Dolan. "Bounced off of me."

Dolan's backyard gave Buzz City a whole new meaning. He housed hundreds of thousands of unwelcome guests.

"I heard a tinging noise," he says. "It was bees hitting the fan."

Honeybee swarms are a common sight in the Queen City. Ed Moyers, president of Mecklenburg County Bee Keeping Association said the first thing to do is don't panic.

"We've been programmed by Hollywood movies that show these scenes of killer bees or other killer insects that are coming in big swarms and attacking people and covering them up," Moyers said.

This year, bee swarms hit early mainly because of the mild winter. Experts say when you see a huge blob of flying bees there are few things you should know.

"If you don't bother them they'll leave you alone," Moyers said. "Don't swat at them. Don't spray them with pesticides."

But not everyone is taking that piece of advice. For the past decade, scientists have been trying to figure out why so many honey bees are dying.

Some experts point the finger at pesticides. He says this should serve as a wake-up call.

"And this is a real concern," said UNCC's Dr. Stan Schneider. "The insects that pollinate plants are necessary for maintaining agriculture, as well as ecosystems."
