Fire Ants

Fire Ants are the scourge of summer fun. I grew up in middle Georgia running around my grandmother's farm and had fire ants in my diapers as a kid. As an adult working as an Extension Agent in Georgia, I answered hundreds of questions about fire ants over the years. I have always despised these creatures and was SO happy when I moved to western North Carolina and found that we had no fire ants.

The Fire Ant Cometh

Unfortunately the ants are showing up more and more locally. In the years that I have lived locally I have found them in parking lots and parks and found them on power line right of ways. The ants hitch rides on cars from places like south Carolina, Georgia and Florida where the ants are already established.

Identifying Fire Ants

How do you know if you have fire ants in your yard? Fire ants build tall mounds from the soil that they excavate from underground. Fire ants look unfriendly, with red bodies and big pinchers. Finally, if they sting you, it feels like someone putting out a match on your skin. Keep children away from mounds as the ants can swarm small kids and sting them many times. If you have an allergic reaction to the sting seek medical assistance.

Fire Ant Life Cycle

The tunnels they create underground house the queen who generates countless eggs. The eggs are cared for by workers and moved up and down vertically in the nest depending on soil temperature. The eggs pupate into workers who can travel up to 300 feet away from the nest to harvest food. Ants will eat anything from plants to animals living or dead. In the spring mounds will sometimes create winged ants who will fly away to start new colonies.

Controlling Fire Ants

There are two ways to control fire ants; individual insecticidal mound treatments and broadcasting baits. The old Texas “Two-Step Method” uses both baits and mound treatment and is highly effective. Place the bait out around a mound. Wait about 5-7 days. Then, apply a liquid mound drench which should kill the remaining workers more quickly. Call the Extension Office to learn more and to report sightings.
