Researchers expect that these spiders will die out in late November, but they could return next year in similar or even greater numbers.
The huge spider – which hails from East Asia – spread widely this year in the north of the US state of Georgia, which frightened the population and puzzled scientists, after it occupied with its thick nets electrical wires, balconies of houses and fields.
Writer Zoe Strozzewski says – a report The Joro spider, which can reach more than 7 centimeters in length when its legs are extended, is a type of weaver insect that makes complex webs resembling a wheel.
And the writer quotes Will Hudson – an entomologist at the University of Georgia – confirming that he killed more than 300 guru spiders in his home. His balcony has become unusable after being filled with these insects. He says: “These nets are a real mess, and no one wants to go out their door in the morning and suddenly spiders’ webs cover their face!”
As for Paula Cushing, an expert in spiders, confirms that the guru poses no threat to humans or pets, and usually only bites when exposed to danger. It is unclear how this species reached US soil, but it was first identified in 2014, in an area 80 miles away in the state capital, Atlanta.
The author quotes Jennifer Turpin, a self-described arachnophobe, who said she stopped cleaning her garden after she once stepped on a guru’s spider web.
Stephen Carter suffers from the same problem, and therefore avoids wandering in any area where he once found traces of the Guru spider, which is widespread in Japan, China and Taiwan, and its females are distinguished by their colors, covered with yellow, blue and red spots.
Scientists believe that this type of spider will spread throughout the American South after it was found in several other cities. It is not clear why it has increased in an unprecedented way this year, and it may be due to changes in precipitation. However, there is a great deal of disagreement among scientists about the effect of this phenomenon on the environment and on the rest of the living organisms.
Meanwhile, Debbie Gilbert, 67, decided not to wait for the results of scientific research, and relied on a zero-tolerance policy for this type of spider, using a stick to kill them and destroy their webs. She says, “I do not encourage killing any living creature, and I live at peace with all the insects and spiders around me, but guru spiders do not belong to this area.”
And entomologist at the University of Georgia, Nancy Henkel, believes that these spiders will play a positive role in eliminating mosquitoes and insects that bite humans and cause spreading diseases and destroying agricultural crops. So she says, “This is wonderful and exciting, these spiders are our friends, they are free in nature and they hunt all the pests that bother us.”
But Anne Ripstra, who studies spider behavior at Miami University, prefers to speak with caution as she assesses the potential effects of a guru, especially since research on the topic is still limited. “I will always feel apprehensive, and I prefer caution when dealing with something that has suddenly appeared in an environment where it does not belong,” she says.
Meanwhile, farmers, nature lovers and gardeners are worried about the safety and presence of other spiders, and the bees that play a role in spreading pollen among plants.
Paula Cushing explains that the Guru is big enough to prey on pollinating insects if they get caught in his nets, but he doesn’t rely on them much for his diet. And the guru can have a positive effect on domestic spiders, if you can use his advanced nets in the fishing process.
Researchers expect that these spiders will die in late November, but they may return next year in similar or even greater numbers, at a time when scientists are unable to provide accurate predictions about this phenomenon.
