Deadly Asian needle ants found in Florida

TALLAHASSEE, FL – Asian needle ants have been detected in Florida, raising concerns about potential health risks. According to the U.S. Forestry Service, these ants have been found near Tallahassee and along Florida’s east coast. Their stings can cause a severe allergic reaction known as anaphylaxis, which is potentially life-threatening. For those with allergies to foods or bee stings, the danger is even more pronounced. Immediate medical attention is advised for anyone stung and experiencing a reaction.

Dr. Debbie Castle, an ant behavior biologist from the University of South Florida, explains that only the worker ants possess the painful sting. The queens and males do not. The sting is comparable to that of fire ants, which are notorious for their painful bites. Individuals who are allergic to fire ant stings are advised to carry an EpiPen as a precaution.

Unlike fire ants, which thrive in grassy areas, Asian needle ants prefer forested regions rich in rotting wood. This preference means they are less likely to be encountered in well-maintained lawns. The invasive fire ant, which arrived in Florida during the 1920s and 1930s, has since spread globally, even reaching China. The introduction of Asian needle ants raises concerns about yet another invasive species impacting the ecosystem.

These ants are believed to have been introduced to the U.S. through international trade, particularly in soil accompanying imported plants and landscaping materials. Their underground and under-rock habitats allow them to hitch a ride unnoticed, leading to their unintentional spread.

Dr. Castle’s fascination with ants began with her background in psychology. She was drawn to the parallels between ant and human social behavior. Ants exhibit complex social structures, providing homes for their queens and young, and engaging in territorial battles. These behaviors offer insights into cooperation and resilience in the face of adversity.

The presence of Asian needle ants in Florida is a reminder of the challenges posed by invasive species. As residents are advised to remain vigilant, especially in wooded areas, the importance of understanding and managing these ecological impacts becomes clear.
