Some unwelcome guests have flocked to the EKU campus in Richmond, but the university has a plan to make them leave.

A large group of starlings have made the campus their home, and EKU officials say the birds are creating a bigger mess than usual this year.

So Thursday night, EKU will begin what's called "bird bombing."

Workers will use something that looks like a small pistol to scare the birds away.

"It's a specialized pellet that will go up in the air, and either make a loud whistling noise, or rise up about 75 to 100 feet and make a loud bang noise."

"Bird bombing" will take place each night between 6 and 7:30, until the starlings get tired of it and move off campus, which usually takes around a week.

We're told the birds usually make their homes around magnolia trees.
