Recent rains are leaving behind stagnant water providing mosquito habitat. Mosquito samples collected reflect a significant increase in the adult mosquito population. This has led to an increase in adult mosquito prevention inquiries from County residents.
Cumberland County participates in the Pennsylvania West Nile Virus Surveillance Program; Mosquitoes carry disease including West Nile Virus.

The County will take additional measures to monitor and suppress the mosquito population and limit the potential for West Nile Virus. Beginning Tuesday, June 2, 2009, the County Vector Control Office will be adding treatments known as mosquito “adulticiding”: spraying areas where adult mosquito populations are very high. This method involves using an Ultra Low Volume sprayer mounted on the bed of a truck dispensing an adult mosquito control material (see website or call for control product information) during the early evening hours. This effort is being made to provide relief in residential neighborhood areas experiencing problems in Western and Southern County municipalities where source habitat is difficult to access.
