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.
This table shows the number of acres treated with larvicide during February and March. The majority of acreage in the winter is in marsh areas that have filled with rainwater. Mosquito control efforts in March were focused in marshes and impounds because it was an unusually rainy month. This work will prevent spring fly-offs of aggressive Aedes mosquitoes.
This table contains the number of each type of service request in March 2018 compared to the three-year average in March. The number of mosquito service requests in March 2018 was considerably lower than the three-year average. This is because a very high number of mosquito service requests in March 2017.
This table contains the number of each type of service request in January and February. Despite being a shorter month, February had more requests for service than January, which were mainly rodent-related.
