These are rejections made of incoming parcel shipments which do not meet the requirements of our JB Exterior Quarantine.

CDFA also conducts inspections of outdoor items from the east coast for the spongy moth. During these inspections an adult JB was found in Orange County in 2007 and Humboldt County in 2015 associated with outdoor items being moved here from the east coast. In 2011 the Fresno County dog team intercepted JB in a single plant being shipped into the state through a parcel service.
