Nearly all civilized countries adopted some form of quarantine control between 14th and 19th centuries, to prevent spread of plague; in 1903 detailed measures against rats were included when connection between plague and rat flea had been demonstrated; 1926 International Sanitary Convention formed basis of regulations as they are today; first serious attempts to destroy entire rodent infestation, of ships were made by fumigating with sulfur dioxide gas, later hydrocyanic acid gas (HCN) was used, and in 1950 sodium fluoracetate (1080); ships have been kept free from rodents during past few years by use of Warfarin Baits, which is anticoagulant and kills rats by reducing clotting power of blood.
