Operations Statistics

Overview

How to Interpret Operations Statistics

Operations statistics tell us what kind of work our vector control technicians spent their time on in the past month. These numbers are useful for helping us make decisions about how to allocate resources or what programs to focus on.

Tables of acres treated refer to larger sources of standing water where mosquitoes may develop. Numbers of sourced treated include smaller residential sources of standing water, such as swimming pools and backyard containers.
