Theft Prevention

California serial number brand on a hiveOur department routinely surveys for unregistered apiaries in Contra Costa County to verify that beekeepers are utilizing the BeeWhere Program.  All beekeepers with colonies located in areas that are not their personal residence are subject to a yearly marking and branding inspection. Colonies placed on agricultural land for pollination services are also required to identify their colonies.

Identification of hives

Food and Agriculture Code (FAC) section 29046 requires beekeepers to identify their colonies when bees are maintained on a premises other than the beekeeper’s own residence. Identification includes marking in dark letters not less than one inch in height on a background of contrasting color with the following:

  • The name of the owner or person responsible for the apiary,
  • His or her address, which at minimum includes city and state e.g. Concord, CA
  • Telephone number

Identification can be accomplished by posting a sign on the entrance side of the apiary, or by directly stenciling the hive.

Branding of hives

A brand serial number may be purchased from the California Department of Food and Agriculture (CDFA) as an additional security measure for theft prevention.  FAC section 29055 makes it unlawful for any person to have in possession any apiary equipment with any serial number brand other than his or her own.  Brand inspections are performed to regulate the use and management of brands.

The purchase of a brand serial number through CDFA is optional.
