Ants found on Thursday, July 27, 2023 and Friday, July 28, 2023 in the Yokohama Port Survey of the National Port Survey (hereinafter referred to as the “National Port Survey”) conducted by the Ministry of the Environment every year. As a result of identifying species by experts, they were identified as fire ants, a specific alien species. The discovery at Yokohama Port has been made since October 2020. Insecticide bait (bait) is installed around the confirmation point.

In cooperation with the Ministry of the Environment, etc., we will continue to conduct surveys and control mainly at locations where fire ants have been confirmed.
