What are the potential effects of southern fire ant stings on humans?

The potential effects of southern fire ant stings on humans primarily revolve around their ability to cause allergic reactions. When stung, individuals often experience pain, swelling, and redness at the sting site. However, some people may be sensitive or allergic to the venom, which can lead to more severe responses, such as anaphylaxis in extreme cases. This allergic reaction can vary in severity among individuals, emphasizing the importance of recognizing it as a possible response to a sting.

The other options do not accurately reflect the reality of southern fire ant stings. While it is true that many people may not experience severe effects, stating they are always harmless overlooks the fact that allergic reactions can and do occur. Additionally, while immediate pain from a sting is common, it is misleading to claim there are no long-term effects, as allergic reactions can lead to complications. Lastly, characterizing the stings as soothing and calming is entirely inaccurate, as they are known for their painful sting rather than any comfort they might provide.
