Red Ants vs. Fire Ants: What’s the difference?

Nobody enjoys getting bitten by ants, especially not fire ants. Fire ants not only bite, they also sting, which is one of the key differences between fire ants and other ant species. Additionally, 2 to 3 percent of people are allergic to fire ants, which makes proper identification especially important.

Distinguishing a fire ant from other ants is tricky; not all fire ants are red and not all red ants are fire ants. Fire ants in the United States belong to one of two categories: imported and native. 

Imported fire ants are the most aggressive and include red and black imported fire ants. Both were both brought to the U.S. by accident in the early 20th century. While less hostile, native fire ant bites and stings hurt just as bad. Native fire ant species include southern fire ants, tropical fire ants, desert fire ants, and little fire ants.

Fire ants thrive in warm climates, especially Southern states. In fact, according to our 2022 national survey, 50% of homeowners in the South have experienced problems with fire ants. Unlike other ants, fire ants have two bumps between their thorax and abdomen. As mentioned above, fire ants don’t just bite, like other ants do. They sting as well.

Differences in behavior can also help to identify a fire ant. Fire ants are extremely aggressive and will swarm instantly if their mound is disturbed. Most other ants take longer to respond if they respond at all. Another distinguishable characteristic is that fire ant mounds do not have openings at the top like regular anthills and are usually located in moist areas, generally popping up after rain.

Deep diving into the distinctions: red ants vs. fire ants

It’s important to recognize the differences between red ants and fire ants. While they might appear similar at a glance, there are distinct characteristics that set these two species apart. 

Let’s explore the key differences that can help you distinguish between red ants and fire ants:

Size and appearance

  • Red ants — Red ants, often referred to as “red imported fire ants,” typically range in size from 1/16 to 1/5 inch (1.5 to 6 mm) in length. Red ants have a two-segmented body with a noticeable narrowing or “waist” between the thorax and abdomen.
  • Fire ants — Fire ants are similar in size to red ants, measuring between 1/16 to 1/4 inch (1.5 to 6 mm). Fire ants also have a two-segmented body but are often more aggressive in behavior.

Nesting behavior and appearance

  • Red ants — Red ant nests are less visible, with no significant mound. These ants tend to build their nests in soil, creating underground tunnels and chambers. Their nests are typically shallow and less conspicuous compared to fire ant mounds. Red ant colonies can be found in various outdoor locations, including lawns and gardens.
  • Fire ants — Fire ants are renowned for their large, conspicuous, cone-shaped mounds of loose soil. These mounds, constructed from soil particles, are a distinctive feature of their colonies and can reach heights of up to 18 inches (45 cm) and are. 

Aggressiveness

  • Red ants — While red ants can bite and sting, they are generally less aggressive compared to fire ants. However, their level of aggression may still vary depending on the specific ant species and circumstances.
  • Fire ants — These ants are known for their aggressive nature, especially when it comes to defending their colonies. Fire ants have a well-structured and organized social system within their nests. When they perceive a threat, they mobilize quickly to protect their queen, brood, and resources. They are highly territorial and will aggressively attack any intruder that comes too close to their nest. 

Range

  • Red ants — Red ants are primarily found in the southeastern United States but have expanded their range to other parts of the country. They are also present in other regions of the world.
  • Fire ants — Fire ants are native to South America but have become invasive pests in the southern United States and other parts of the world. They are particularly well-established in the southern states.

Diet

  • Red ants — Red ants are omnivorous, feeding on a variety of insects, small animals, and plant matter. They are less likely to scavenge for food and are not as aggressive foragers as fire ants.
  • Fire ants — Fire ants are aggressive and opportunistic predators and scavengers. They will attack and kill small animals, including insects and even small vertebrates. They are known for their voracious appetites.

Antenna structure

  • Red ants — Red ants have 10 segmented antennae with a two-segmented club at the end. The club is usually larger and more noticeable.
  • Fire ants — Fire ants have 11 segmented antennae with a two-segmented club at the end. Their antennae are generally less conspicuous.

Color variation

  • Red ants — Red ants tend to have a more consistent reddish-brown coloration across the body. There is less variation in color between individual ants.
  • Fire ants — Fire ants can display more color variation within the colony. While they are generally reddish-brown to reddish-black, some individuals may have a darker coloration.

Sting sensation

  • Red ants — Red ant stings are painful but typically not as severe as those of fire ants. Their bites and stings often cause discomfort and itching. The pain from their stings is often described as sharp and burning, typically subsiding within a few hours to a day.
  • Fire ants — Unlike many other ant species that simply bite, fire ants deliver painful, burning stings. They grasp onto their target with their mandibles and then insert their stinger to inject venom. The venom contains alkaloids that cause intense pain and a burning sensation, hence the name “fire” ants. Fire ant stings can persist for several days and may result in painful, itchy, pus-filled blisters. Some individuals even experience severe allergic reactions when stung or bitten by a fire ant.

These differences should give you a more comprehensive understanding of red ants and fire ants. Remember that accurate identification is crucial for effective pest management and ensuring your safety in areas where these ants are present.
