An atomizing pump is installed on the back of a truck. This produces a fine mist of chemicals and oil carrying agent. The chemicals must contact the adult mosquitoes to kill it. Normally, the truck should travel at 10 miles per hour. There is monitoring equipment that monitors vehicle speed, application rate, and time. An alarm warns operator if speed is not correct. Monitoring equipment produces a record of operators’ activity for the supervisors.
The spraying begins at dark. One-third of the city is sprayed each night. The city's phone notification system calls each zone the day they are going to be sprayed. If you do not receive a call you can make sure you are signed up to receive notifications online.
During especially heavy infestations, the first route is immediately begun again after completing the third route.
