Subject: Red imported fire ant range expanding in California

Red imported fire ants (Solenopsis invicta) have long been a problem in the U.S. southeast, with smaller populations in New Mexico, Arizona, and Nevada. They were in southern California by 1998, but were recently discovered further north in Sacramento County. This infestation is centered in an RV park, and it is speculated that a park visitor may have introduced the ants, possibly from another state. The CDFA website contains a map characterizing the spread of this pest in the U.S., http://www.cdfa.ca.gov/phpps/pdep/rifa/html/english/facts/rifaTIME.htm.
