If you wish to have your property removed from all future, routine mosquito adulticiding and larviciding applications, please call the Office of Mosquito Control at 973-948-4545.

Over 160 species of birds have been found infected with West Nile virus (WNV). The mortality rate of crows infected with WNV is very high. Because of this, we use crows as an indicator for WNV presence. Crows that are in good condition will be picked up by an Office of Mosquito Control inspector and will be submitted to the State Department of Health for WNV testing. Please note that dead birds must meet strict testing criteria (dead for less than 48 hours, no signs of trauma, and no ants or maggots).

If you have a freshly deceased crow that meets these criteria, please call the Sussex County Department of Environmental and Public Health Services at 973-579-0370 or click here to submit a report online.

Neglected pools can produce mosquitoes which may elevate the risk of West Nile virus in the community. To report a neglected pool for inspection and treatment, please call the Sussex County Department of Environmental and Public Health Services at 973-579-0370 or click here to submit a report online.

If you are being bitten by adult mosquitoes or suspect nearby standing water may be suitable habitat for larval mosquitoes, please call the Sussex County Department of Environmental and Public Health Services at 973-579-0370 or click here to submit a report online.

Mosquito control workers will visit your property as well as any nearby sites to inspect and treat larval mosquito habitat. If necessary, traps for adult mosquitoes may be set in order to collect and identify the species of adult mosquitoes already on the wing. This information can help direct future larval control efforts and be useful in determining if adulticide spraying is required.
