Virus Activity

A map of virus activity in the Coachella Valley. Traps are set up throughout the valley in both urban and rural habitats as part of our surveillance program to detect arbovirus activity. 

Application Activities

In an effort to lower the number of mosquitoes and reduce the risk of disease transmission to people by infected mosquitoes, the District treats areas with elevated virus activity. These wide-area applications are typically conducted by air or by truck. Scheduled applications are posted here.

Public Health Pesticides

As part of our Integrated Vector Management strategy, the District uses pesticides to eliminate vector-borne disease threats to the public health. This  environmentally-sensitive approach poses minimal risk to humans, animals, and the environment. Labels and Safety Data Sheets (SDS) for the use of these products by state-certified vector control technicians are availabe here.
