The answer to 'why is my fire ant swarms' is that fire ant infestations are caused by colonies of the invasive red imported fire ant. These aggressive ants build large mounds in lawns, gardens, and other areas, and their painful stings can be a serious problem for homeowners. Fire ant colonies can grow rapidly, leading to large swarms that emerge from the mound, especially after rain or when the mound is disturbed.
Fire ants are attracted to warm, moist environments and often infest areas with lots of vegetation, mulch, or rotting wood. They are particularly common in the southeastern United States. Homeowners may notice fire ant mounds, see swarms of ants, or experience painful stings as symptoms of an infestation. To control fire ants, it's important to treat the mounds directly with approved insecticides or baits, and to eliminate conditions that attract them to the area.
