Large Scale Pesticide Treatments

When the risk for human disease reaches a specific threshold because the population of vectors is sufficiently high, pesticides may be applied on a large scale. 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.

 For more information about pesticide use and treatment planning please read:

The Facts about Pesticide Use and Treatment Planning

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. 

Public health and safety is our number one priority!

Note: There were no large scale pesticide treatments performed in 2015
