The major ant pest in the southern United States in the early 1900s was the Argentine ant Linepithema humile (Mayr), so there was little concern when imported fire ants were detected in and around Mobile, AL, by Loding (1929).

Seasonal studies on a 1,200-ha isolated infestation of Solenopsis invicta Buren located in McMinn County, TN, were initiated in 1993 and continued through 1997 and data collected over four winters indicate that consecutive days at a low ambient air maximum temperature is more indicative of S. Invicta winter survivability than minimum temperature.
