12 which of the zodiac animals are just the four pests?

12 In the Chinese zodiac, rats are the four pests, and the "four pests" refer to flies, mosquitoes, rats and cockroaches. The "four evils" have a long history. February 1958 the Central Committee of the Communist Party of China and the State Council issued "Hygienic Instructions for Eliminating Four Pests". It is proposed that the task of eliminating flies, mosquitoes, rats and sparrows should be completed within 10 year. Gradually, sparrows were "rehabilitated" and replaced by bugs. Later, due to changes in social life, bugs were replaced by cockroaches.
