Why do fire ants not leave the mound?
This is because the ants do not exit the colony through the mound but through underground tunnels connected to it. This allows the ants to safely travel back and forth to different places, such as food or water sources. A fire ant mound contains the eggs and larvae of the growing colony, along with countless worker ants.
How to locate a fire ant mound?
Fire ant mounds can be found around your property as fluffy domed mounds of soil. Fire ant mounds are typically found several days after a rainstorm. Fire ants work underground to create a network of tunnels. The excavation of these tunnels is what causes the mound to form on top of the ground, and this is what commonly indicates the presence of fire ants. This mound provides cooler temperatures and protection of the tunnels located under the mound. The size and capacity of a fire ant mound depends greatly on weather and temperature. During cold wet periods, the mound is built higher to protect the fire ant larva and pupae, collectively known as brood. Similarly, during hot and dry periods, a fire ant mound may not be as tall, allowing the natural elements to affect the mound more. This is why during the springtime, fire ant mounds are more heavily prevalent. In the spring, mounds appear taller and are easily seen.
How to tell a fire ant mound from different ant mounds?
One common difference between fire ant mounds compared to other ant mounds is that there is no opening in the center of the mound. Fire ants travel through a network of tunnels underground to forage for food and to tend to their queen. One way to tell if a mound is filled with fire ants is to puncture the mound. Fire ants are very aggressive and will defend their queen at all costs. Once the mound is disturbed worker ants will flood out of the mound and will attack whatever caused the disruption to their home. Fire ants also have a distinctive bite compared to other ants, as their unique mix of venom causes a burning sensation in their victims and will result in a raised blister a day or two after being bitten.

What are the roles of ants in a fire ant colony?
Fire ant workers are haphazardly divided into different size classes, namely minima, minor, media, and major workers. The major ants are known for their larger size and more powerful mandibles typically used in macerating and storing food items (i.e. as repletes), while smaller workers take care of regular tasks (the main tasks in a colony are caring for the eggs/larvae/pupae, cleaning the nest, and foraging for food). However, Solenopsis daguerrei colonies contain no workers, as they are considered social parasites.
How to identify Solenopsis spp. ants?
Solenopsis spp. ants can be identified by three body features—a pedicel with two nodes, an unarmed propodeum, and antennae with 10 segments plus a two-segmented club. Many ants bite, and formicine ants can cause irritation by spraying formic acid; myrmecine ants like fire ants have a dedicated venom-injecting sting, which injects an alkaloid venom, as well as mandibles for biting.

Although most fire ant species do not bother people and are not invasive, Solenopsis invicta, known in the United States as the red imported fire ant (or RIFA), is an invasive pest in many areas of the world, including the United States, Australia, China and Taiwan. The RIFA was believed to have been accidentally introduced to these countries via shipping crates, particularly with Australia when they were first found in Brisbane in 2001. These ants have now since been spotted in Sydney for the first time. They were believed to be in the Philippines, but they are most likely to be misidentified for Solenopsis geminata ants.
How long do fire ants live?
The estimated potential life span is around 5 years and 10 months to 6 years and 9 months. Young, virgin fire ant queens have wings (as do male fire ants), but they often cut them off after mating. Although, occasionally a queen will keep its wings after mating and through her first year.
How do fire ants get into a mound?
Unlike other kinds of ants, fire ants have no nest entry on the mound itself. They enter the nest via tunnels that may reach several feet or more beyond the mound itself. Though it is the most recognizable sign of the presence of fire ants, a mound is not necessary for the survival of a fire ant colony. During especially hot or dry weather, colonies tend to move deeper into the ground, foregoing the palatial mounds that are so obvious in moderate weather. New colonies may not build a visible mound for months or longer, depending on soil and weather conditions.

They are most active in the spring and fall, when the weather is warm and damp, building their nests and foraging for food.
What do ants do in the winter?
Ant's are known for keeping a clean house. They will create trash piles called middens which store all of the colony's garbage.

The middens can grow considerably with the colony's dead after a battle with another colony or an application of pesticides.
How do you know if you have ants?
It is important to be on the look out for them when you are outside. If you unknowingly stand on a mound or on one of its tunnels, you could find yourself covered in ants before you realize it.

When you have identified a fire ant mound on or near your property, you need to be very cautious of it. There are two reasons for this.
What color are fire ants?
The fire ants you are most likely to see are red-imported fire ants, and the worker ants of the species are mostly a reddish-brown color, except for their rear section which is black. Most of the ants you see will be worker ants, so identifying them is most important. Again, coloring is not the best way to identify red-imported fire ants.
Why are fire ants named after fire?
Shortly after the red marks appear, a small blister will form on top of it. These bites and stings often feel like they are burning or extremely itchy, and that is a big reason fire ants are named after fire. It’s important not to scratch the bites because doing so can result in infection.
How to protect yourself from fire ants?

Overview
Behavior
A typical fire ant colony produces large mounds in open areas, and feeds mostly on young plants, insects and seeds. Fire ants often attack small animals such as small lizards and can kill them. Unlike many other ants, which bite and then spray acid on the wound, fire ants bite only to get a grip and then sting (from the abdomen) and inject a toxic alkaloid venom called solenopsin, a compound fro…
Appearance
The bodies of mature fire ants, like the bodies of all typical mature insects, are divided into three sections: the head, the thorax, and the abdomen, with three pairs of legs and a pair of antennae. Fire ants of those species invasive in the United States can be distinguished from other ants locally present by their copper brown head and thorax with a darker abdomen. The worker ants are bl…
Queens, males and workers
Fire ant queens, the reproductive females in their colony, also are generally the largest. Their primary function is reproduction. Typically, a fire ant queen will seek to establish a new colony following a nuptial flight, wherein it will use its special venom to paralyze offending competitors, in the absence of workers for defense. Fire ant queens may live up to seven years and can produce up to 1,6…
Invasive species
Although most fire ant species do not bother people and are not invasive, Solenopsis invicta, known in the United States as the red imported fire ant (or RIFA), is an invasive pest in many areas of the world, including the United States, Australia, China and Taiwan. The RIFA was believed to have been accidentally introduced to these countries via shipping crates, particularly with Australia w…

Phorid flies, or Phoridae, are a large family of small, hump-backed flies somewhat smaller than vinegar flies; two species in this family (Pseudacteon tricuspis and Pseudacteon curvatus) are parasitoids of the red imported fire ant in its native range in South America. Some 110 species of the genus Pseudacteon, or ant-decapitating flies, have been described. Members of Pseudacteon repro…
Species
The genus Solenopsis contains over 200 species. Not all species included in the genus are known as fire ants, but most are small slow-moving ants which are unable to sting, called thief ants. "True" fire ants are but a group of about 20 species of Solenopsis which are larger, and will viciously sting in swarms whenever disturbed. Some of the most studied species include:
• Solenopsis invicta Buren, 1972
