Red imported fire ants (Solenopsis invicta) have not been reported as established in California. However, there have been occasional detections of these ants in the state, primarily through interceptions at ports of entry or in nursery shipments. The California Department of Food and Agriculture (CDFA) and other relevant agencies closely monitor and respond to these detections to prevent the establishment of red imported fire ants in California. The state's climate and ecosystem present unique challenges for the establishment and spread of these invasive ants, but ongoing vigilance and rapid response efforts remain crucial to prevent their introduction and potential impacts on agriculture, ecosystems, and public health in California.

Argentine ants (Linepithema humile) are a highly successful invasive species known for forming massive supercolonies, which can span vast distances and contain millions of individuals. These supercolonies consist of interconnected nests that cooperate rather than compete with each other, allowing for rapid expansion and domination of new territories. Unlike many other ant species, Argentine ants exhibit a remarkable lack of aggression toward individuals from neighboring colonies, enabling them to form these expansive networks
