Joro Spider Invasion Wreaks Havoc on South Carolina's Native Ecosystems
15 Nov
Summary
- Joro spider infestation spreading rapidly in Upstate South Carolina
- Invasive species outcompeting native spiders, harming pollinators
- Residents struggle with Joro spider webs in their backyards
According to recent reports, experts are sounding the alarm about a rapidly growing Joro spider infestation in Upstate South Carolina. The Joro spider, an invasive species native to East Asia, was first introduced to the Southeastern United States around 15 years ago and has since been wreaking havoc in the region.
Since the Joro spider's initial documentation in South Carolina in 2018, its populations have exploded, with the infestation becoming particularly severe in the northwest corner of the state. The female Joro spiders are easily identifiable by their unique yellow markings and pink patterns, while the smaller male spiders are typically found in the females' golden-colored webs.
While the Joro spider is not harmful to humans or pets, it poses a significant threat to local pollinators and native spider species. Experts have observed a concerning decline in the populations of native orb-weaver spiders, which play a crucial role in controlling pests and contributing to the overall ecosystem balance. The invasive Joro spiders are outcompeting these native species for resources, leading to a concerning loss of biodiversity.
For residents in the affected areas, the Joro spider infestation has become a nuisance, with the large webs appearing in backyards and populated areas. One Greenville resident, Nekitah Hunt, described the experience of encountering the spiders up close as she stepped out of her house, saying, "Coming out the house and kicking. Once I came in, and it was like, right there in my face, and I didn't realize it."
Experts recommend that homeowners can either physically remove the Joro spiders or use natural pest control methods, such as vinegar, citrus fruits, or lavender and mint plants, to manage the infestation. While the Joro spider is not an agricultural or forestry pest, its impact on the local ecosystem is significant, and addressing the issue sooner rather than later is crucial to preserving the region's natural biodiversity.
