Their fangs are small and incapable of puncturing human skin, which makes them harmless to both people and pets. Their appearance may invoke fear, but they pose no documented danger to humans.

Contrary to some of the more alarming headlines, Joro spiders' ability to 'fly' is actually a natural phenomenon known as ballooning. This process involves the spiders using their silk to catch the wind, allowing them to travel significant distances through the air. This ability is not unique to Joro spiders but is common among many other types of spiders, which use it as a means of dispersal and can occasionally lead to them turning up in unexpected places.

The introduction of the Joro spider into non-native regions like North America may raise concerns about their impact on local ecosystems. As an invasive species, there is the potential for these spiders to compete with native species for food and habitat, disrupt local biodiversity, or potentially introduce new pathogens. However, detailed impacts on local ecosystems in the U.S. are still under study, and initial observations suggest that they could potentially help control pest populations.

Though they may not be welcomed by all, Joro spiders contribute to biodiversity and, being effective predators, they play a role in managing pest insects, which could benefit agricultural and garden areas. Continuing research and monitoring will provide further insights into their role within North American ecosystems and any longer-term effects their presence may have.
