The red imported fire ant is an ant that comes from South America. It has spread to Australia, New Zealand, parts of Asia, the Caribbean, Europe and the United States, where it is seen as a serious pest. Its sting burns, and in some people it causes a dangerous allergic reaction.1

Leef in

Native to South America. Introduced to Australia, New Zealand, several Asian and Caribbean countries, Europe and the United States.1

Suid-Amerika

Tuis

It lives in a wide variety of places, including rainforests, deserts, grasslands and disturbed land. It is dominant in altered areas and thrives in urban areas, where it nests alongside roads, buildings and in electrical equipment. Colonies build large soil mounds that have no visible entrances.1

Wat eet dit?

It eats dead mammals, arthropods, insects, seeds and sweet substances such as honeydew from hemipteran insects, with which it has developed relationships. It forages on warm or hot days, though it may stay outside at night.1

Hoe om dit te herken

Workers are red and somewhat yellowish, with a brown or black rear section (gaster).1
Males are completely black.1
Workers come in different shapes and sizes.1
Colonies form large soil mounds with no visible entrances, because foraging tunnels lead to places far from the nest.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

About 95% of its venom is made of water-insoluble piperidine alkaloids called solenopsins, and the rest is a mixture of toxic proteins that can be especially strong in sensitive people. Most stings cause intense burning and swelling, followed by sterile pustules (small fluid-filled bumps) that can last several days. In some people, a severe allergic reaction called anaphylaxis can occur, with dizziness, chest pain, nausea, severe sweating, low blood pressure, shortness of breath and slurred speech.1

Hoe gevaarlik is dit vir mense?

More than 14 million people are stung by these ants each year in the United States, and many are expected to develop allergies to the venom. Between 0.6% and 6.0% of people may suffer anaphylaxis, which can be fatal if left untreated. More than 80 deaths have been recorded from attacks by this ant.1

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

Wat doen dit as dit bang is?

It uses its venom and chemical signals (pheromones) to defend itself and its nest.1

As dit steek

People who only have pain and pustules need no medical attention. People who develop anaphylaxis need emergency treatment with adrenaline. Whole body extract immunotherapy is used to treat people who are allergic and is regarded as highly effective.1
Was en koel die steke af.
As die persoon sukkel om asem te haal, die gesig of keel swel, of hy voel flou, is dit 'n allergiese noodgeval: bel jou noodnommer.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

When water levels rise, these ants build rafts to float on.1

A single mature colony can contain between 500,000 and 2,000,000 individuals.1

Over 1,800 scientific papers have been published using its name, and it is one of the most studied insects on the planet, rivalling the western honey bee.1

Workers dispose of scraps and dead ants on refuse piles outside the nest, a behaviour called necrophoric behaviour.1

Workers can live for several months, while queens can live for years.1

Mite-breker

Mite: The name "fire ant" comes from fire or burning nests.

Waarheid: The name comes from the burning sensation caused by its sting.1
