ELIZABETH, NJ - Due to recent confirmed human cases and a positive mosquito sample of Eastern Equine Encephalitis (EEE) in Berkeley Heights, Union County Mosquito Control is scheduled to treat sections of Summit adjacent to Watchung Reservation and the Passaic River corridor -- subject to FAA approval and weather permitting -- by helicopter application on Wednesday, October 2, between the hours of 7 - 10 p.m.

When / if the aerial spraying is approved by the FAA, the process will be carried out by a State of New Jersey, Department of Environmental Protection contracted helicopter and involve adulticide spray, Zenivex Estofenprox, a member of the non-ester pyrethroid chemical family which is considered safe for humans and pets. When the spraying is confirmed, all sporting or other outdoor activities beginning at 7 p.m. or after will be canceled that night.  

Temperature plays a critical role in mosquito activity and weather conditions need to be suitable for the aerial spraying to occur. Residents are instructed to check ucnj.org/engineering-public-works-facilities-management/bureau-of-mosquito-control/ for further information, including contact information for those with questions.
