Workers wearing respirators returned to the closed main branch of the Huntington Public Library Saturday to battle the bedbugs found there last week.
Wearing white, Tyvek suits, workers with Victor Pest Control of Massapequa Park labored into the afternoon as a steady stream of people walked up to the library's main entrance on Main Street only to learn that its doors were locked.
Katherine Heaviside, a spokeswoman for the library, said the workers sprayed the chemical Nuvan to eliminate the bugs.
"Although . . . [bedbugs] were found in a small area, 10 by 10 feet on the main floor, the entire library, all three floors," will be sprayed with the chemical, she said.
The chemical leaves "no effects" after 24 hours and has been "100 percent successful in killing eggs, bugs and larvae," Heaviside said.
The library will remain closed until Tuesday morning to ensure that the chemical dissipates, Heaviside said.
Workers, who were protected by a guard, declined to comment in the parking lot behind the library yesterday.
On Friday, the exterminating company workers conducting a routine inspection found bedbugs in the crevices of several chair cushions. The library was then closed.
Heaviside said three or four bugs were found in an area away from books.
The closure came as a surprise to the patrons who showed up Saturday to return books or take out movies.
For the most part, they took the closure in stride - believing that a little inconvenience was better than checking out bedbugs.
Last month, bedbugs temporarily closed the children's section of the Central Islip Public Library. It has since reopened.
