They are about 1/8″ in length. They can bite but do not sting. They are a scavenger but prefer sweets. DO-IT-YOURSELF: Find the trail outside by placing corn syrup in suspect area.

They are not as abundant in urban areas as they are in rural areas. Mounds are usually insignificant. They are scavengers and are attracted to nearly anything organic but prefer proteins. DO-IT-YOURSELF: Despite what you may have heard, opposing fire ants will not destroy each other. Boiling hot water directly into mound will only kill those in direct contact with water. Grits barely work. The best option is to broadcast a protein or carbohydrate BAIT labeled for fire ant control in the general area of the sighting. Try not to disturb the mound.side.
Red Imported Fireant
Red Imported Fire ants are a very common problem in our area. They are 1/8″ to 1/4″ in length. They are known for their burning, itchy sting, followed by a pustule. Most insect bites are for defense. This pest stings as a predator. This is why you rarely get one sting. They gather in groups and all sting at the same time trying to bring you down. This pest is found in the yard year round but the mounds are visible only certain times of the year. They are attracted to nearly anything organic but are mostly attracted to proteins. DO-IT-YOURSELF: Note: The mound is only the tip of the colony. Opposing colonies fighting to death is only a myth. Boiling water poured directly into mound will only kill those in direct contact with water and topical insecticides don’t eradicate. Apply a protein or carbohydrate BAIT labeled for fire ants by broadcasting the area of the sighting without disturbing the mound.

They are about 1/8″ long and are found most commonly in moisture areas. Once established, their colonies are huge! The largest nest I’ve found was about 20′ long, nesting in insulation under a home. They are attracted to sweets only. Control is very difficult. DO-IT-YOURSELF: Apply a sweet bait in the trails in and out, including the attic and crawl. Pay particular attention to plant contact with home. Their activity rapidly appears and disappears which leads you to believe they are gone. Usually, they’re not. Follow up weekly.
