Giant Venomous Flying Spiders Are Real:
The Joro spider, with a leg span of about four inches, is a venomous arachnid that is expected to invade the New York area this year. Originating from Japan, they were first spotted in the Southeastern U.S.
Initial Infiltration in the U.S.:
Georgia was "ground zero" for these spiders in 2021, where they were seen in both urban and rural areas. They have since spread to other states in the Southeast.
Characteristics and Lifespan:
According to Jason DiBiase of Rochester Pest Pro, female Joro spiders have a lifespan of up to 12 months and a leg span of about four inches.
Possible Spread to New York and New Jersey:
Although Rochester has not yet seen these spiders, they could already be appearing in New York City and New Jersey. They might enter Rochester through truck shipments and the port.
How to Identify Joro Spiders:
The Joro spider is described as having a "striking appearance" with vibrant yellow and black coloration. They are distinctive due to their ability to fly by "ballooning," using silk threads to be carried by the wind.
Prevention Measures:
There are no definitive ways to eliminate Joro spiders, but residents can take preventative measures such as knocking down webs, using exterior pest treatments, and calling local pest control services.
How Joro Spiders Came to America:
The Joro spiders likely arrived in the U.S. through cargo shipments, international trade, and personal travel. Their adaptability and rapid reproduction have allowed them to establish themselves successfully in the Southeast.
Potential Expansion Across the Eastern U.S.:
Invasive species expert David Coyle from the University of Clemson predicts that the Joro spiders will be able to inhabit most of the eastern U.S., with their range expected to continue expanding northward.
