About Kometoban
Kometoban is S.T. Corporation's insect repellent for rice bins, released in 2003. It uses a jelly mixed with natural chili peppers to keep insects away from stored rice, and the jelly shrinks over time so a user can see when to replace it. The lineup covers 5 kg and 10 kg of rice and pre-washed rice, and the company says it holds a 90 per cent share of its Japanese market segment, from INTAGE data covering 2022 to 2025.
