There are over 12,000 species of ants, and every single one differs greatly from the other. There are 280 fire ant species around the world. A sting from a fire ant isn’t just uncomfortable but may cause fatal anaphylaxis if you’re allergic to it. Symptoms from the bite are immediate. It will start to itch and then turn into a big, red welt.
The bites eventually turn into fluid-filled pustules. Their bites are strong enough to kill a small animal and cause a severe human reaction in people. You’re more likely to come into contact with them in the summertime (Far and Wide).
