Routine vector and disease surveillance are essential components of a comprehensive mosquito and vector control program. Surveillance means that we trap adult mosquitoes, ticks and yellowjackets on a regular basis in multiple locations to understand their population growth during the season and from year to year. Surveillance also means that we test mosquitoes and ticks from our traps to track diseases they may carry. Human cases of vector-borne diseases like West Nile virus are tracked by our partner agencies Placer County Health and Human Services and the California Department of Public Health.
Our vector and disease surveillance program is robust and monitors the abundance of:
- Presence of West Nile virus and other vector-borne diseases
Trapping and testing methods are different for each vector and disease, but we always use the results to assess the risk to people, inform the public and make preventative or responsive vector control treatments in the most safe, timely and effective way possible.
