On Wednesday August 21, Langley Air Force Base will conduct an aerial spray mission over the base beginning around 8:30 PM. 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 concern, please contact York County Mosquito Control at 757-890-3790.
