Between August 27 - August 30, Langley Air Force Base will conduct an aerial spray mission over the base. The only areas that will be sprayed are Langley AFB and Craney Island. Due to the turning radius of the spray planes, York County residents may see the spray plane turning over the area, even though the county will not be sprayed. If there are any questions or concerns, please contact York County Mosquito Control at 757-890-3790.
