The Asian citrus psyllid (ACP) is widely established in urban and suburban areas throughout Southern California. Large-scale eradication of ACP in these environments is not feasible. Rather, the goal is to reduce psyllid populations to slow the establishment and spread of Huanglongbing (HLB) disease.  In 2016-17, the number of HLB-infected trees started to rapidly increase.  Dozens of HLB-infected trees have been found in residential Los Angeles and Orange counties and more recently in Riverside County. These trees have been removed, but there are likely more out there that contain the disease.  Homeowners can help by reporting trees they suspect have the disease and if they are in a community where HLB-infected trees have been found, to consider removing their citrus trees.  

See the tabs at the left to answer questions about what steps you should take to help in the effort to control the psyllid and disease in order to protect California citrus.
