Overview

• Joro spiders, native to East Asia, have been spreading in the U.S. since the 2010s, first appearing in Georgia.
• These spiders use a 'ballooning' technique, releasing silk threads to travel on wind currents.
• Joro spiders are expected to move further north, potentially reaching New York and New Jersey.
• The spiders are large and colorful, with females growing up to 4 inches and spinning yellow-gold webs.
• Experts advise against killing Joro spiders, as they are harmless and may help control pest populations.
