What should I do if I find it?
If you find the Asian citrus psyllid, you should check the Distribution of ACP in California tab (above) to determine if the psyllid and its parasites (Tamarixia) have been found in your area.
If you live in Central or Northern California, where the psyllid is rare, act fast and call the CDFA Hotline immediately 1-800-491-1899 to report the psyllid. They will verify that it is an Asian citrus psyllid and treat your citrus trees in an attempt to rid the area of this pest.
If you live in southern California, then the psyllid is well established. You can call a licensed pesticide applicator or treat your citrus trees yourself with insecticides to keep the psyllid numbers low. See the tab at left for guidance on natural enemies and insecticide treatments. The lower the number of psyllids, the less likely the HLB disease will spread.
If you think your citrus tree has symptoms of the disease, act fast, call the CDFA hotline 1-800-491-1899 or your local Ag Commissioners office and someone will take a leaf sample and determine if it is infected with the bacteria that causes huanglongbing.
Keep a close watch on the map of HLB finds and the news reports about HLB. If an HLB-infected tree has been found in or near your neighborhood, consider taking out your citrus tree. The tests that determine if a tree has the disease, often don't reveal the disease until the tree has had it for many months or years, meanwhile psyllids could be spreading the disease. If the tree is removed it eliminates the need for pesticides to control the psyllid and prevents your residence from becoming a source of infection for your neighbor's trees.
If you no longer enjoy your citrus tree or do not want to routinely fight pests and disease, the tree should be removed. Removing unwanted citrus trees helps prevent Huanglongbing from spreading in the community.
