Bed bugs were common pests worldwide before World War II. They were almost completely eradicated in many countries by good hygienic conditions and application of insecticides. These pests are currently reemerging in many developed countries. We conducted a literature review and an internet search using the key word, bed bugs, to evaluate the status of bed bug resurgence in China. The results showed that the occurrence of bed bugs dramatically increased from 4 reports in 2007 to 67 in 2012. Bed bug infestations were reported from 23 provinces of China, with the most severe infestations occurring in Guangdong Province. Bed bugs were reported to commonly invade dormitories, private homes, rented houses, and public transportation facilities. Based on internet reports, about half of the people bitten by bed bugs claimed to have developed clinical reactions, and approximately 5% required medical treatment. This study demonstrates that China also has undergone a bed bug resurgence, which should be addressed by the multidisciplinary actions involving both governments and the public.
