We talk quite a bit in the conservation community about invasive species and the threats they pose to habitats and ecosystems.We have to deal with invasive species on conserved lands, typically invasive plants like kudzu and privet, which can spread rapidly and choke out native vegetation.
But there is one species we have to deal with far too regularly, one that can create an even more immediate and direct threat – the fire ant. There are more than 280 species of fire ants worldwide, but the invasive fire ant found in the Southern United States is known as the red imported fire ant, Solenopsis invicta. Many times we encounter fire ants by inadvertently stepping on one of their mounds, in which case they may climb onto your foot or leg and attack as a group.
The mounds fire ants create also pose problems for agriculture, as they interfere with farm machinery and can destroy the roots of vegetation and crops. BRADES, Montserrat – The Department of Environment is extending its outreach programme by publishing a brochure to raise awareness of the Invasive Red Fire Ants. The fire ant is about 2 to 6 millimeters long, reddish brown and looks similar to several local ant species. The brochure provides useful information on how to recognize the fire ant and nest and what precautionary actions one can take to avoid being stung.
The document also covers what should do if they have been stung by the fire ants and actions one can take to control the spread of the Invasive Red Fire Ant species on island. This map predicts areas in the United States that are susceptible to invasion by the red imported fire ant, Solenopsis invicta. New Zealand is trying to keep these ants out and actively monitors for RIFA around ports of entry.
As an invasive species, they now live in many countries across the world, it is believed that they reached these countries via shipping crates.
These fire ants are more aggressive than most native species and so have pushed many species away from where their local habitat, even possibly into extinction. Fire ants are renown for their ability to survive extreme conditions, they do not hibernate, but can survive cold conditions as low as -9°C (16°) despite originating from South America. Fire ants can uniquely deal with a flood situation, they gather to form a raft with the queen in the middle, they float until they come across dry land, see fire ant videos below. To learn about one of the interesting ways in which we have chosen to control the invasive fire ants see bio control. Fire ants normally nest underground in grassy areas creating soil mounds up to 50cm in height. Established colonies of fire ants have been found with up to 150 thousand to 2 million ants, with multiple queens.
Fire ants have a strong, painful and persistent sting that produces lumps on our skin which can last for days and even hospitalise some.


The FDA estimates an annual $5 billion spent on medical treatment, damage and control in infested areas because of this one ant species! Dufour’s gland – is believed to be involved with the laying of chemicals that guide other ants and perhaps the attraction of mates.
Gamergates – rare female worker ants which can mate and reproduce, keeping the colony alive after the queen dies. Hymenoptera – the Order in which ants occur, the Order also includes bees, wasps and sawflies. Major worker – the larger worker ants found in a colonies caste, also known as soldier ants.
Mandibles – the ants main jaws, these are used for cutting, holding, fighting, and digging. Median workers – worker ants found in polymorphic species that are sized between minor and major workers. Nantics – first born ants that tend to be smaller than typical established colony workers. Outbreeding – reducing the probability of interbreeding closely related individuals, thus reducing disease or genetic abnormalities. Repletes – a caste of ant that stores large amounts of liquid food in its crop i.e honey pot ants. Trophallaxis – The ‘mouth to mouth’ exchange of regurgitated liquids between adult ants or adults and the larvae.
In this Saturday’s Austin American Statesman newspaper, I was shocked to see that Rasberry crazy ants were found in Central Texas! At the time, he said that there were no sightings of crazy ants in Central Texas, but he predicted that they would be coming. The newspaper article said that the crazy ants were in a condominium in Briarcliff along the shores of Lake Travis, and they probably came from gardening material from Houston, where they were first found by a pest control man, Tom Rasberry, in 2002. They can take over areas from fire ants, which may sound good, but they come in such massive numbers that they can overwhelm and suffocate wildlife, damage electrical systems, and make houses unlivable. The news of crazy ants coming to Central Texas, so close to my own home, shows the importance of educating people about invasive species and preventing their spread.
The Texas Invasives database has a lot of information about all the different invasive plants, animals, insects, and pathogens that are trying to invade Texas. If applied within a few minutes after being stung, they can reduce the pain and prevent the formation of the pustules.
The first ant will bite, which releases a pheromone, and other ants will then bite immediately afterwards.


The brochure goes on to explain the impact the ants can have on agriculture, health, infrastructure, and how it can disrupt recreational and social events.
Predictions are based on climate and current northernmost distributions of red imported fire ants. They have been successful at eradicating the ants twice: In 2001, a single red imported fire ant nest was found at Auckland International Airport.
These ants are now a common pest in southern North America, Australia, Taiwan, Philippines and South China.
Jerry Cook, Associate Vice President of Sam Houston State University, at the 2011 Texas Invasive Plant and Pest Conference. Cook said they’re called crazy ants because they move around very quickly and erratically, moving here or there. This is particularly distressing, as the hemlock’s ecosystem is home to numerous different types of species, many of them rare, that are mainly associated with that particular forest type. The sting of a fire ant can be extremely painful and even dangerous, especially if you are stung multiple times. Fire ants have venom that causes pain and inflammation, and those allergic to the venom can have a severe reaction requiring medical attention. However, if you think you might be allergic to the fire ant’s venom it is important to seek professional medical help. The FDA estimates more than $5 million is spent annually on medical treatment, damage and control of invasive fire ants; approximately $750 million in agricultural losses are attributable to them.
Another example is the chestnut blight, although less commonly thought of as attributable to an invasive species since its largest impact was so long ago.
That invasive fungus wiped out the American chestnut, and along with it, nearly half of our eastern forests in the 1920s and 1930s. Quail and other ground-nesting birds, as well as native bees, are commonly attacked by fire ants. The decline of other species such as southern hognose snakes, has also been attributed, at least in part, to fire ants.
Results of the model predict that red imported fire ants will likely move 50-100 miles north in Oklahoma and Arkansas.
