The offices of the Hachette Book Group on 237 Park Avenue in Manhattan are undergoing treatment after an attack of bedbugs, according to a Wall Street Journal report by Melanie Grayce West.

After days of after-hours treatment, the company closed early yesterday and is remaining closed all day today for “final treatment — which is more potent, and involves chemicals,” says a company spokeswoman.

The report notes that “The incident follows recent closures at other public spaces and offices, including a triage room at Kings County Hospital in Brooklyn, a Victoria’s Secret on the east side, the offices of Euro RSCG Worldwide downtown, an Abercrombie & Fitch at the South Street Seaport and the Hollister Epic store in SoHo.
