The East Asian species are not aggressive and their venom not a danger to humans or pets.
The scariest thing this Halloween – a spider the size of a human palm, spotted recently in Bucks County.
Joro spiders, characterized by their large size and vibrant coloration, have become an invasive presence in various regions, including Warminster Township, where one was spotted on Sept. 24 outside a home.
These East Asian spiders can be recognized by their cylindrical bodies, which are about the size of a human palm. They use a unique method called "ballooning," in which they release silk threads to catch the wind and travel through the air.
This adaptation aids in their spread, raising awareness of their presence, according to The Advance of Bucks County.
Although their appearance can be alarming, Joro spiders are generally not aggressive. Reports from research centers indicate that their venom poses little threat to humans or pets, and they are unlikely to build webs indoors, according to the article.
Their presence has been documented in Bucks County, with sightings occurring in early September and late September, suggesting a seasonal peak in visibility, per the report.
The arachnid was first observed in Georgia in 2013, and since then, it has been spreading across the eastern United States.
The recent confirmations in Bucks County involved the capture of several spiders, per the report, which were subsequently removed by an entomologist. These spiders typically remain non-threatening unless provoked, reinforcing their reputation as relatively harmless creatures.
When it comes to their bites, Joro spiders are not considered a significant medical concern, according to The Advance. A bite usually resembles the sensation of a bee sting and is not severe unless an individual has an allergy. Most people experience only mild discomfort, and bites are unlikely to break the skin. Basic hygiene measures can help manage any potential irritation, per the report.
For those dealing with Joro spider encounters, several removal strategies are recommended. Engaging professionals, such as entomologists or pest control technicians, is one effective approach, according to the article.
Alternative methods include using specific insecticides, removing webs, and keeping potential hiding spots clear of debris. Direct removal techniques, like wrapping the spider in its web and stepping on it, are also suggested.
Their shy nature leads them to avoid contact, and their bites are usually mild. As they continue to spread, per the report, understanding their behavior and implementing proper removal techniques can help manage their presence effectively.
