New York City’s bed bug epidemic has spread to yet another landmark in the city that never sleeps — the United Nations, officials at the world organization said yesterday.

The pests appeared at places like the Empire State Building and Bloomingdale’s before reaching the city’s center of international diplomacy on the East Side.

The U.N. press office said a bed bug-sniffing dog had confirmed the presence of bed bugs in furniture in the basement of the Dag Hammarskjold Library, where the offices of the team overseeing the U.N. headquarters’ $1.9 billion renovation project are housed.

“This furniture has been moved to a part of the building not occupied by staff to facilitate fumigation,” it said.

The library is a three-story annex to the main building.

“Bed bug infestations have been found in many public and commercial buildings throughout New York City indicating a worsening problem,” the U.N. statement said.

In August, the pest extermination company Terminex said that New York is the most bed bug-infested urban center in the United States.
