All known infested properties in Los Angeles County have been treated and monitoring is underway. All known sites in San Bernardino County have been treated and are being monitored. As expected, additional mound sites are still being found at scattered locations within the quarantine zone. The unusually cool spring and early summer slowed ant activity. Over the past few weeks, with rising temperatures, an anticipated increase in fire ant reports has occurred.
Ants are more active in hot weather.
Project officials emphasize that statewide surveys for the Red Imported Fire Ant should continue, to identify any infestations that escaped from Southern California prior to the start of the program.
