Fire ants were found in a container unloaded in the Port of Kobe on June 2017 for the first time in Japan. Since then, ports across the country are taking measures against fire ants. Port of Shimizu personnel are also are checking for fire ants at the container yard continuously following the first patrol on June 19th.
In addition, we have set insect traps in the container yard and surroundings and exchange them about once a week to check whether or not fire ants have been captured.

Furthermore, in Fukuroi city fire ants were found in a container transported from the Port of Shimizu.
We set insect traps and insecticidal bait where fire ants or red imported fire ants were found, and exchanged them on regular basis to grasp living condition of fire ants and to exterminate them.
Furthermore, in the Sodeshi No.1 Wharf and Shin-Okitsu Wharf, we set traps everywhere whether fire ants were discovered or not.
If you find ants considered to be fire ants in Port of Shimizu, kill them with insecticide at first and contact Security and Maintenance Division in Port Authority (054-353-2202) immediately.
