Dorchester County operates a Mosquito Control Program to protect its citizens from the spread of mosquito borne diseases by spraying pesticides (insecticides), applying larvicide to low-lying areas, and educating its citizens on reducing the conditions that foster increases in the mosquito population.

Mosquitoes are a pest that can cause itchy bites, but they can also cause more serious health issues like spreading diseases. The most common diseases that could potentially be carried by mosquitoes in South Carolina include: West Nile, Eastern Equine Encephalitis, La Crosse Encephalitis, Saint Louis Encephalitis, and dog/cat heartworm.

Ground Spraying and Larvicide Briquettes

Dorchester County has two trucks for ground spraying. Beginning in April 2017, personnel will spray 6 zones per night, Monday-Friday from 9:00pm to 5:00am.

The two chemicals used for ground spraying are Permanone Ready-to-Use and Pursuit/4-4 ULV. These are similar chemicals and both chemicals have a quick knock down rate. These two chemicals are for adult mosquitoes, as opposed to larvae.

Dorchester County responds to mosquito complaints in low lying areas, with treatment during the day, using a larvicide chemical to help prevent hatching. The chemical used is Altosid XR Extended Residual Briquettes.

Steps to protect yourself from mosquito bites

Drain, fill, or eliminate sites that have standing water. 

Empty or throw away containers that have standing water.

Keep mosquitoes outside. Use air conditioning or make sure that you repair and use window/door screens.

Avoid Mosquitoes. Most mosquito species bite during dawn, dusk, twilight hours, and night. Some species bite during the day, especially in wooded or other shaded areas. Avoid exposure during these times and in these areas.

Wear insect repellent. Yes! It is safe. When used as directed, insect repellent is the BEST way to protect yourself from mosquito bites—even children and pregnant women should protect themselves. 

Cover up. When weather permits, wear long-sleeve shirts and pants.
