Brick's will be open Friday, a day after a left the building shut down.
Barricades blocked the entrance to the Chambers Bridge Road building on Thursday, after it was closed following bed bugs being discovered in the tax office, officials said.
But by Thursday night, the all-clear was given to reopen the building.
"We have been given the go ahead to reopen tomorrow," said township spokesman Ed Moroney, in an e-mail.
Moroney said a pest control service brought in a specially-trained dog to sniff out where the bed bugs were, "and the appropriate actions were taken."
While known as "bed bugs," the tiny, parasitic insects don't necessarily live in beds or even residential homes. According to the North Carolina State University Department of Entomology, bed bugs are most often transported from one location to another by piggy-backing on luggage, briefcases and similar items. Offices, which include a great amount of ductwork and false ceilings, provide passageways for the bugs to spread.
One of the most high-profile bed bug appearances came in 2010, when radio host Howard Stern's studio in the SiriusXM Satellite Radio office building in New York City was treated due to an infestation.
Bed bugs feed by injecting their mouthparts into a host – a human or an animal – and injesting its blood.
