Giant venomous flying spiders, known as Joro spiders, are making their way to the East Coast of the United States, with areas like New York and New Jersey expected to see an influx. These spiders, which can have legs up to four inches long, were originally found in Japan, Korea, Taiwan, and China but have since spread to parts of northern Georgia, first appearing there in 2014.
The Joro spider is identifiable by its vibrant yellow and grey body and its unique ability to “fly” by using its silk to catch the wind. While their venom is not considered dangerous to humans or pets, their large size and appearance can be alarming. David Coyle, a scientist at Clemson University, emphasized that these spiders are likely here to stay, as their native range’s climate is similar to much of the eastern U.S.
José R. Ramírez-Garofalo, an ecologist at Rutgers University, suggested that it’s only a matter of time before they arrive in New York City. To manage the presence of Joro spiders, Coyle recommends physically removing them with a stick or broom, as pesticides can be overkill and harm other species. Maintaining a tidy home, sealing entry points, and vacuuming spider webs are also effective preventive measures.
As these spiders continue to spread, researchers are monitoring their impact on local ecosystems. While the Joro spider’s presence may be unsettling to residents, understanding their behavior and role in the environment is crucial. Scientists hope that public awareness and proper management strategies will mitigate any negative effects and help communities coexist with these new arachnid neighbors.
