Inspections for Aedes aegypti, the yellow fever mosquito: Maps below

Throughout the next few months, our staff is going door-to-door in all seven cities, asking to inspect around homes and properties. Why? We are looking for mosquito breeding sources. In particular, Aedes aegypti, the invasive yellow fever mosquito. We ask that you please cooperate with our staff. The inspections are used to suppress this aggressive mosquito.

District personnel wear tan and green uniforms with our logo on the shirt. Each person will have a District-issued identification badge. We urge residents to remove all standing water and unnecessary containers around their homes and report daytime biting mosquitoes to the District.
