Thanks to the cooperation of Orange County residents and local agricultural officials, the California Department of Food and Agriculture (CDFA), in partnership with the United States Department of Agriculture (USDA) and the Orange County Agricultural Commissioner, has announced the end of the Oriental fruit fly quarantine in Orange County. This follows the successful eradication of the invasive pest.
The Oriental fruit fly is known to infest over 250 types of crops, including citrus, fruits, nuts, and vegetables. An infestation was detected in November 2024, leading to a quarantine that covered parts of Garden Grove, Anaheim, Santa Ana, Fountain Valley, Orange, Costa Mesa, and Huntington Beach. During this period, potential host crops were restricted from being moved from their original locations unless they met specific treatment or processing standards.
Victoria Hornbaker, director of CDFA’s Plant Health and Pest Prevention Services Division said: “The diligence and collaboration from Orange County residents proved critical as we worked together – federal, state and local agencies – to eradicate the Oriental fruit fly from this area, but our work is not done.” She highlighted an increase in invasive fruit fly populations across California over the past two years and emphasized public awareness and resource commitment to prevent future infestations.
Despite lifting the quarantine in Orange County, officials warn that threats from non-native species persist. Invasive pests pose risks to agriculture, environment, economy, as well as homegrown produce. Residents are urged to help prevent future introductions by allowing agriculture crews access for inspections or treatments and avoiding bringing agricultural products into California from other regions.
Additional guidelines include purchasing plants and produce from licensed nurseries to avoid spreading pests. Residents should inspect their gardens for signs of invasive species and report any findings to CDFA or local agricultural offices.
