[ARCHIVED] Union County spraying for mosquitos in sections of Summit


Please be advised: Due to recent confirmed human cases and a positive mosquito sample of Eastern Equine Encephalitis (EEE) in Berkeley Heights, New Jersey, Union County Mosquito Control is planning to treat sections of Summit adjacent to Watchung Reservation and the Passaic River corridor by helicopter application on Wednesday, October 2, 2019, between the hours of 7PM and 10PM, weather permitting. Residents who live in these areas and their pets are advised to remain indoors during this specified time period.

The EPA does not require relocating or taking special precautions during mosquito control spraying, people may choose to avoid or minimize exposure by staying indoors during the application to the immediate area, keeping windows shut, window fans and window air conditioners off, or set to circulate indoor air, during spraying, keeping children's toys indoors, keeping pets indoors, as well as their food, water dishes and toys.

There are five other municipalities involved in this operation: Berkeley Heights, Mountainside, New Providence, Scotch Plains and Springfield. 

From September 2019:

During routine testing, the Union County Bureau of Mosquito Control found that a mosquito pool in Union County has tested positive for Eastern Equine Encephalitis (EEE).  Please read the message below from the Westfield Regional Health Officer:

“Even though a mosquito was found, the Union County Bureau of Mosquito Control is spraying diligently.  They have been looking for and testing mosquitoes all season and will continue to aggressively spray throughout the county, particularly areas most prone to heavy mosquito populations and schools.”

EEE is a rare but serious disease caused by a virus that can effect people of all ages.  It is generally spread to humans through the bite of a mosquito infected with the virus and can cause severe illness and possibly lead to death in any age group; however, people under the age of 15 are at particular risk.

You can take personal precautions against mosquito bites by staying indoors during dusk and dawn.  Other steps families can take to reduce the risk of EEE include using EPA-approved bug spray, wearing long sleeves and pants while outdoors, and eliminating sources of standing water, such as containers and bird baths.

For more information on EEE visit the NJ Department of Health website at and the Center for Disease Control and Prevention’s webpage at

Residents can also contact the health department at 908-789-4070 for more information.
