Red Imported Fire Ant 

Red imported fire ants (RIFAs, for short) get their common name from their ability to inflict painful bites and stings. These dark reddish-brown ants are an invasive species found throughout the southern part of the U.S. 

Pest Description:

• Color: Dark reddish brown
• Legs: 6
• Shape: Segmented; oval
• Size: 1/16 to 1/4”
• Antennae: Elbowed with 10-segmented antenna with a 2-segmented club
• Region: Southern United States, from Maryland to Texas, California and New Mexico
• Habits: These red ants build large mound nests in open, sunny areas and can be found foraging indoors. These ants are frequently introduced into new areas through potted plants, shrubs and trees.
• Habitat: Red imported fire ants usually nest in soil near structural foundations or in landscaping. Although these fire ants are often found outdoors, they can gain access to buildings through HVAC systems and AC units. Once inside these ants have been known to gnaw on electrical wiring and clothing, especially if the clothing has been soiled.
• Threats: Fire ants can severely injure lawns, humans, young birds who disturb a nest. The sting of a red imported fire ant is painful and often results in a raised welt that becomes a white pustule. Often, a person stung by red imported fire ants will receive multiple stings from more than one of the ants. Persons allergic to insect stings will react more severely to red ant stings.
