What can I do?
Request Service
Request Prenotification

Upon Request, the pesticide applicator business shall provide a resident with notification at least 12 hours prior to the application, except for Quarantine and Disease Vector Control only, when conditions necessitate pesticide applications sooner than that time. Submit prenotification request or call 973-940-5225

Report a dead bird

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).

Report a freshly deceased crow that meets these criteria or call 973-940-5225.

Report neglected pool

Neglected pools can produce mosquitoes which may elevate the risk of West Nile virus in the community. Report a neglected pool or call 973-940-5225.

Request service around your property

If you are being bitten by adult mosquitoes or suspect nearby standing water may be suitable habitat for larval mosquitoes, please request service around your property or call 973-940-5225.

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.
