"Our annual pest control vendor did not observe any rats or fleas," said David Pascal of the Los Angeles Department of City Services. "In City Hall, on floors one through four there was some activity noticed in the form of rodent droppings."
Officials said 1,800 flea traps were installed in City Hall and other buildings. The report by a private pest control company said it found nothing out of the ordinary.

"No. 1 priority is the health of the public that comes here and also city employees club," said Tony Royster of the Department of City Services. "That's top priority and that's what we're focusing on."
City staff said efforts have been stepped up to fight the rodent issue, including more cleanups outside City Hall.
At least one employee who works at City Hall is believed to have contracted typhus. Public health officials have reported a recent outbreak of the disease on downtown's Skid Row, with 19 cases documented in downtown since October.
The report also recommends solutions, such as more frequent vacuuming, cleaning and keeping all food in secure containers.
