Phorid flies like Pseudacteon curvatus parasitize and kill fire ants.

Introducing or conserving the natural enemies (diseases, parasites and predators) of imported fire ants can help control them. These natural enemies kill fire ants or make them less able to compete with other ant species. The most effective biological control organisms for large-scale programs are those that spread by themselves from mound to mound and persist from year to year. Three species of parasitic “phorid” flies (Diptera: Phoridae), including Pseudacteon tricuspis, P. curvatus and P. litoralis, have been released and established in parts of most southeastern states.  Read more about Natural and Biological Control of Fire Ants.
