The County has developed a plan that subdivides Dorchester County into fifty (50) spray zones - please visit the Spray Zones page on this site, to locate your zone. 

Note: The County may amend the boundary of these zones from time to time to provide for more efficient mosquito abatement spraying. 

• Spraying runs from 9:00 PM - 5:00 AM, Monday thru Friday
• Random visual inspections during the height of mosquito season will be conducted
