Oriental Fruit Fly Quarantine Lifted in Contra Costa County

Statewide

Following the successful eradication of the Oriental fruit fly in Contra Costa County, the California Department of Agriculture has declared an end to the quarantine covering parts of Brentwood and Oakley, as well as surrounding areas in parts of Antioch, Bethel Island and Discovery Bay.

The announcement comes 10 months after officials first detected populations of the Oriental fruit fly in the area. This destructive pest has been eliminated through the cooperation and diligence of Contra Costa County residents and local agricultural officials, the California Department of Food and Agriculture (CDFA), working in coordination with the United States Department of Agriculture (USDA) and the Contra Costa County Agricultural Commissioner.

“We’re pleased to report this is the third Oriental fruit fly quarantine lifted in California this year,” said Victoria Hornbaker, director of CDFA’s Plant Health and Pest Prevention Services Division. “These recent successes prove that through the cooperation of residents across the state and our partners, eradication of invasive species is possible.”

While several fruit fly quarantines have now been lifted in California, three additional quarantines remain and still threaten the state’s natural environment, agriculture and economy. To review all active quarantine maps, please visit CAFruitFly.com.

When at home, residents are encouraged to stay vigilant for signs of invasive pests. To help prevent any future introductions of invasive species, residents should follow these guidelines:

  • Cooperate with agricultural officials and allow them access to your garden to place traps, inspect plants, conduct necessary treatments or remove potentially infested produce.
  • Determine if your property is located within an active quarantine area by visiting CAFruitFly.com.
  • Buy fruit trees and vegetable plants from licensed California nurseries. Purchasing agricultural goods from uncertified sources can spread invasive pests. Source your plants locally and responsibly. To find a licensed nursery near you, visit CDFA’s Directory of Licensed Nurseries.
  • Inspect your garden for signs of invasive fruit flies or maggots and report any findings to CDFA at 1-800-491-1899 or your local county agricultural commissioner’s office.
  • When entering the United States from another country, avoid bringing agricultural products — including fruits or vegetables.
