The Asian citrus psyllid has been found throughout Southern California. To date, only one tree infected with HLB has been discovered and it was in a backyard tree in Los Angeles County. To protect your citrus, it is important to:

  • Respect county, state and national quarantine laws.
  • Not bring citrus into California from other countries or states.
  • Not move citrus from your backyard.
