Large-sc​​ale Pesticide Treatments

Currently, there is no public health emergency to warrant large-scale treatments

Public health and safety is our number one priority.

Large-scale pesticide treatments are reserved for severe conditions, including abnormal mosquito population spikes and public health emergencies.  Thankfully, the District has not observed these conditions since 2016.

These treatments are made with a truck-mounted applicator that disperses an ultra-low volume mist into the air. All of the pesticides we use are registered with the US Environmental Protection Agency (EPA) and are chosen based on their ability to have a maximum effect on target organisms while having a minimal effect on humans, pets, and the environment.

This page was created as a resource for the community to get the most up to date information about the pesticide treatments executed by this District, both completed in the past and planned for the future. If the information you need is not here, please call the District and we will be happy to answer any questions you may have.
