Richland County set to begin mosquito control efforts

Crews with Richland County will soon begin spraying for mosquitoes, as Vector Control staff begin their annual campaign to protect public health by reducing mosquito-borne illness.

Workers with Vector Control will conduct surveillance on mosquito populations, treat larval breeding sites and spray for adult mosquitoes in densely populated areas of the County (outside Columbia city limits).

Spraying is one component of the County’s integrated pest management program, which also uses surveillance, public education and mechanical and biological controls to help alleviate nuisance and disease caused by the pests, said Olin Towery, Vector Control manager. The County does not apply pesticides according to a set schedule, so a specific start date is not set.

Trucks will usually spray between midnight and dawn; however, spraying could happen earlier as conditions warrant. When a spray truck is nearby, residents should remain indoors to allow the driver to thoroughly cover the area.

Residents can help reduce mosquitoes by inspecting their property for potential breeding sites and taking the following preventive measures:

• Empty, overturn or remove water-holding containers such as tires, cans, bottles, buckets and flower pots.
• Use EPA-registered insect repellents that contain DEET, picaridin, IR3535 or oil of lemon eucalyptus according to label instructions.
• Clear drainage ditches of debris and weeds.
• Pack tree holes with sand.
• Clean clogged roof gutters.
• Keep boats overturned, drained or covered (covers should not collect water).
• Stock ornamental ponds (water gardens) with top-feeding minnows.
• Maintain swimming pools properly.
• Change the water in pet dishes, birdbaths and containers used to root plants at least weekly.
• Ensure rain barrels have screens to prevent mosquitoes from accessing the collected water, and use the water as soon as possible.
