The California Department of Food and Agriculture has begun an eradication program in a 10-square-mile area in parts of Garden Grove, Orange and Santa Ana after six guava fruit flies were trapper there earlier this month.

The area is within the Los Angeles Basin.

The state and federal governments have not imposed a quarantine over the area.

The eradication will involve applying small globs of a bait that contains a male fruit fly attractant. Inspectors will apply the bait tations on street trees, light poles and other similar surfaces, according to a news release.

The bait also will contain minute amounts of a pesticide that will kill the males once they land on the material.

The goal is to reduce the male population to the point where females cannot find a mate. Eventually, the population dies out for lack of reproduction.

The treatments are repeated every two weeks for up to two of the fly’s life cycles.

Most eradication projects are completed in two to three months if no more flies are detected.

Guava fruit fly larvae feed on a variety of soft fruits, including oranges and peaches. The feeding and subsequent dropping render the fruit unmarketable.
