Native to Africa, the destructive Bagrada bug, Bagrada hilaris, was first spotted in Los Angeles County during the summer of 2008. It can now be found throughout Southern California, including Ventura County.
This invasive insect is a major pest of crop plants. Populations can build up quickly. The heaviest infestations are often found in locations where little or no pesticides are used including organic farms, community gardens and residential vegetable gardens.
Adult Bagrada bugs are 5-7 mm long with orange and white markings on their black, shield-shaped bodies. Because of their size, shape and coloring, Bagradas are often mistaken for beneficial lady bugs by residents not familiar with this pest.
