Fire ants, a venomous, highly invasive nonnative pest, have been spotted over the past few months in various parts of Japan, prompting the Environment Ministry to both warn the public to seek immediate treatment for stings and take measures to prevent further infestation.
First detected June 9 in Amagasaki, Hyogo Prefecture, fire ants had been identified in 10 locations nationwide as of July 27, from Oita Prefecture to Shinagawa Ward, Tokyo.
The ministry has confirmed one injury caused by a fire ant; a male worker in his 30s developed a rash on his left arm after being stung in a warehouse in Fukuoka on July 27.
