Contrary to popular belief that these spiders are aggressive and competitive with local species, the researchers found that Joro spiders cannot display this behavior. While most spiders quickly resume their normal activities after the animal leaves, Joro spiders remain dormant for more than an hour and calm down until their “unrest” wears off. The study compared the responses of more than 450 spiders from 10 different species.
Relatively harmless to humans and pets, Joro spiders rarely bite unless provoked, and their teeth are too small to pierce the skin if they bite.
Although the Joro spider is an invasive species and is rapidly spreading to the Southeast, its timid nature suggests it is not aggressive towards other spiders or humans. They have adapted to urban environments and often set up their networks in unexpected places such as power lines, traffic lights and gas stations.
