The Vector Control Program at CCNCPHD will continue implementing its integrated mosquito management approach, which includes routine surveillance, larvicide treatments, public education, source reduction efforts, and targeted spraying when necessary. This comprehensive strategy is designed to reduce mosquito populations while minimizing environmental impacts and protecting public health.
While the mosquito control products used are approved for public health use, residents are encouraged to take the following precautions during scheduled spraying periods:
• Remain indoors during active spraying when possible
• Close windows and doors during treatment hours
• Bring pets indoors or keep them away from spray areas
• Cover outdoor furniture, toys, and pet dishes
• Wash homegrown fruits and vegetables before consumption
• Individuals with respiratory sensitivities should take additional precautions as advised by their healthcare provider
Residents are also encouraged to help reduce mosquito breeding and bites by:
• Removing standing water from containers, gutters, birdbaths, and tires
• Using EPA-approved insect repellent
• Wearing long sleeves and pants during dawn and dusk hours
• Ensuring window and door screens are properly maintained
Spraying may be delayed or rescheduled due to rain, high winds, or other weather conditions.
Please call 3-1-1 to report abandoned property, high grass, or standing water.
