Invasion of Joro Spiders in U.S. Northeast

Giant, venomous spiders that fly through the air, known as Joro spiders, are expected to invade the U.S. Northeast via a technique called ballooning. While they are not harmful to humans, they pose a threat to other critters like butterflies and wasps.

Invasive Jorō Spiders Arriving in Northeastern US

Giant black and yellow Jorō spiders from China are set to arrive in northeastern US states this summer. Although venomous, their poison is weak and fangs can't pierce human skin. Experts predict they will spread across the east coast and beyond, but they prefer staying outside. No fatalities have been reported.
