The four pests were flies, mosquitoes, rats, and cockroaches. They are very harmful to human health because they can spread many diseases. Rats could transmit diseases such as plague, leptospirosis, tsutushi disease, typel fever, and epidemic hemorrhage through parasitic fleas, urine, and blood. Flies spread viral infections such as rabies, typhoid fever, ascaris, typhoid fever, and other diseases through their body hair, claw pads, and vomiting while eating. Mosquitoes spread diseases such as malaria, Japanese B Encephritis, Dengue Fever, and filariasis by sucking human blood. Cockroaches carry a variety of pathogenic organisms inside and outside the body, which can spread viral infections, all kinds of gastroenteritis, and parasitic diseases. The campaign to eliminate the four pests was aimed at improving the living environment of the city, preventing the spread and epidemic of diseases, and protecting the health of the people.
