The discovery of a mated female Oriental fruitfly near Sacramento has prompted the state to establish a 79-square-mile quarantine around the North Highlands area.
The quarantine restricts movement of host plants.
Eradication involves what's known as attract and kill, according to a news release.
Workers squirt a mixture that contains a male attractant and a small dose of pesticide on light poles, street trees and other similar surfaces.
Males are attracted the mixture and die after eating it.
Treatments will be repeated every two weeks for two fly life cycles beyond the last trap catch. At a minimum, that's four applications.
The Oriental fruit fly is found throughout much of southern Asia and is endemic in Hawaii. It has a broad host range.
