Preserves may OK mosquito spraying

In a move officials say could protect DuPage County against mosquito- borne illnesses, the forest preserve district may allow spraying to kill adult mosquitoes on a caseby- case basis. Commissioners are reviewing a proposed mosquito policy that outlines criteria that must be met before insecticides can be used to target adult mosquitoes on district land. The existing policy allows for “adulticide” during a public health emergency. But that policy is vague, officials said. — Robert Sanchez
