In Vietnam, we have Trần Quang Thiều, dubbed vua diệt chuột – king of exterminating rats, from BÌnh Vong village, Thường Tín province, North of Vietnam. Originally a farmer, Trần Quang Thiều invented his own mousetraps in order to kill off rats attacking his rice fields. He’d also carefully studied the behavior pattern of different rats in the area and learned where they like to hid and how they choose their routes and succeeded in placing the traps at their most vulnerable spots. Among 43 types of rats in Vietnam, 32 types succumber to his traps. In 2000 he started traveling around the area to help people, openly sharing his trapping methods and mousetrap designs. By 2006 he opened his company, exterminating rats from not just rice fields but factories, hotels, schools, big buildings, etc. They’ve killed over 10 million rats.
