The California Department of Food and Agriculture (CDFA), in cooperation with the United States Department of Agriculture (USDA) and County Agricultural Commissioners, has initiated local regulatory measures to eradicate and prevent the statewide spread of invasive fruit flies.
Quarantines for the Mediterranean fruit fly and Oriental fruit fly have been established following detections of the pests. The Mediterranean fruit fly quarantine encompasses the cities of Fremont and Newark in Alameda County and the city of Milpitas in Santa Clara County. The Oriental fruit fly quarantine covers areas in and around the cities of Santa Ana and Garden Grove in Orange County.
We Need Your Help!
- Now is a critical time for residents in fruit fly quarantine areas to protect their backyard fruits and vegetables from invasive fruit flies.
- To prevent the spread of invasive fruit flies through homegrown fruits and vegetable, residents living in the invasive fruit fly quarantine areas are urged not to move any fruits and vegetables from their properties.
- Fruits and vegetables may be consumed or processed (i.e. juiced, frozen, cooked, or ground in the garbage disposal) at the property where they were picked.
- If they are not consumed or processed, please dispose of them by double-bagging in plastic bags and putting the bags in the garbage bin for collection, not green waste.
-
If you are in an established quarantine area:
- Please do not compost fruit or vegetables. Double bag and dispose of them in the regular waste bin, not the green waste bins.
- Don’t let ripened homegrown produce fall to the ground. Remove mature produce that has fallen to the ground by double bagging and disposing in the regular waste bin, not the green waste bins.
- Before entering the United States from another country, declare agricultural products — including fruits or vegetables — to U.S. Customs and Border Protection – Help us protect our agriculture, natural resources, and unique biodiversity from invasive fruit files – Please Don't Pack a Pest when traveling or mailing/receiving packages.
- Buy fruit trees and vegetable plants from licensed California nurseries, as receiving agricultural goods from uncertified sources can spread invasive pests. Source your plants locally and responsibly. To search for 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.
- Please cooperate with agriculture officials and allow them access to your garden to inspect plants.

Description
- The Mediterranean fruit fly is a short, squat fly about 1/4 inch in length (Fig. 1). It has a blackish thorax marked with silver; a tan abdomen with darker stripes extending across the abdomen; and clear wings with two light brown bands across the wing, another along the distal front edge, and gray flecks scattered near the base.
