Insects & Other Vectors

About Us


The Health Department works to minimize the potential for human disease, discomfort, injury, and annoyance by vectors as well as minimize the potential for illness and environmental pollution from the use of pesticides and related control measures. We also monitor mosquito and tick populations to assess public health risks.

Zika Virus


Zika virus disease (Zika) is a disease caused by the Zika virus, which is spread to people primarily through the bite of an infected Aedes species mosquito. Anyone who lives in or travels to an area where Zika virus is found and has not already been infected with Zika virus can get it from mosquito bites. The main mosquito that transmits Zika, Aedes aegypti, has not been found in Lake or surrounding counties. The Lake County Health Department and others actively monitor mosquito populations to determine the types of mosquitoes present and if they may be carrying diseases.
