Red fire ant bites are typically red and appear similar to hives, according to WebMD. Due to the sting, the bites itch and burn. Some bites can fill with pus and become painful to the touch.
To treat red fire ant bites, ice or anti-itch ointments can be applied to relieve the itching and pain, according to Healthline. Scratching the bites increases the risk of infection. The bites should heal within a week on their own.
In some cases, the toxins can trigger a severe allergic reaction, especially if the ants attack in a swarm or bite multiple times, warns Healthline. Symptoms include difficulty breathing, dizziness and nausea. The allergic reaction typically manifests shortly after the initial bites occur.
Red fire ants are extremely aggressive and attack in large numbers, reports Healthline. They are known to swarm up vertical surfaces to defend their nests. Each red fire ant can sting multiple times and anchor themselves into place by biting through the skin. Some nests can contain as many as 200,000 ants.
Red fire ants are extraordinarily invulnerable, says Healthline. They cannot be drowned and survive in temperatures as low as minus 10 degrees Fahrenheit. While they prefer to eat other insects, they can also eat other animals and crops to survive.
