From July 27 through July 30, Langley Air Force Base will conduct aerial spray exercises over the base. 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. The spray mission is scheduled for July 28 (July 29 rain date), and the only areas that will be sprayed are Langley AFB and Craney Island. If there are any questions or concern, please contact York County Mosquito Control at 757-890-3790.
