Spraying of the Cicero Swamp and Surrounding Areas Scheduled for Thursday, August 31, 2023

UPDATE, 8-31-23: Due to winds being greater than 7mph on Thursday evening, the aerial mosquito spraying of the Cicero Swamp and the immediate surrounding areas has been delayed. The spraying is now planned for Friday, September 1, 2023.


ONONDAGA COUNTY, AUGUST 30, 2023 – The forecast is showing favorable weather conditions for aerial mosquito spraying of the Cicero Swamp and the immediate surrounding areas on Thursday, August 31, 2023 after 6:30 pm. The spraying was postponed from an earlier date due to weather.

The decision to spray was made as a result of mosquitoes that were found positive for eastern equine encephalitis virus (EEEV) and West Nile Virus (WNV) from traps located in the Cicero Swamp area. Additional mosquito pools collected on August 22 were found positive for EEEV and WNV from from an Island Road trap and EEEV from a trap on Taft Road.

This proactive measure is an attempt to interrupt the mosquito breeding cycles. Reducing the number of mosquitoes (although it is temporary) can reduce the number of mosquitoes available to transmit the virus to humans.

If weather or wind conditions are unfavorable on Thursday, the spraying will be conducted on the next appropriate day and will be announced through local news, social media, and other communication channels. Residents in the spray areas will be notified by phone through the 911 emergency notification system.

The designated spray areas are generally bounded on the north by Route 31, on the west by Northern Boulevard, on the south by Taft Road, and on the east by the county line (Chittenango Creek). Roads included in this area are: all or parts of Route 298, Bull Street, Eastwood Road, Island Road, Cicero Center Road, Fergerson Road, Ferstler Road, and Oxbow Road.
