"We were just sitting on our couch, turned off the TV and could hear some buzzing in the walls," Tyler Judd of Provo, Utah, told NBC News.
So they called bee-removal specialist Albert Chubak.
"(It was) not in the ceiling, not in the sofa," Chubak said in a YouTube video. "So we started listening to the wall, and we identified them in the wall."
Chubak found a bee colony with between 40,000 and 60,000 bees.
