New York City's pre-eminent performing arts center made the discovery in a dressing room of its David H. Koch Theater. It's the home of the New York City Ballet and the New York City Opera.
The theater is currently dark. The opera's fall season opens Oct. 27. The ballet company last occupied the building on Sunday.
Spokeswoman Maggie McKeon confirmed the outbreak. It was first reported online on Wednesday by the New York Observer. It cited an Oct. 8 e-mail from the theater's managing director Mark Heiser. He said treatment to rid the theater of the tiny pests was under way.
The bugs have been discovered in theaters, clothing stores, office buildings, housing projects and posh apartments throughout the city.
