An invasive species of poisonous arachnid called the redback spider, which was first discovered in Japan 28 years ago in Osaka Prefecture, has now spread across nearly the entire country, according to the National Institute for Environmental Studies and other sources.

An eight-year-old girl was stung by venomous spiders in Krabi province on July 13, leading to health complications. A previous case of spider bite had caused a person's death in the area.
