The Florida Department of Agriculture and Consumer Services has declared victory over the Mediterranean fruit fly in Pompano Beach.

The department had been waging an eradication against the pest since January, when two flies were picked up during routine trapping, according to a news release. Two additional flies were detected in the coming weeks.

The eradication program consisted of stripping the crop from host plants near the positive traps and spraying the soil with spinosad, an organic insecticide.

The state also released millions of sterile male Medflies weekly over a 63-square-mile area.

The theory is the sterile males will inundate an area, making it difficult for a wild female to find a non-sterile male with which to mate. Eventually, the population will die out for lack of reproduction.

To declare eradication, the state had to go through at least three fly generations, each about 21 days, without detecting a Medfly.
