The recent resurgence of bed bugs (Cimex spp.) in many developed countries has drawn increasing attention worldwide. The status of urban bed bug infestations were investigated in Shenzhen and Dongguan, two major cities in southern Guangdong Province of southern China, based on pest control service records from two different companies (one during 2012 and another during 2013). The results showed that Shenzhen and Dongguan have a severe problem with bed bug infestations: the control of bed bugs is a constant concern, except during the winter. In Shenzhen, a similar number of premises were treated for bed bugs in central business districts and suburban districts. However, in Dongguan, more premises were treated for bed bugs in suburban districts than in central business districts. The treatment rate for worker sleeping quarters, apartments, hotel, and private houses in Shenzhen was 53.8, 43.0, 1.9, and 1.3%, respectively. The percentage of treated rooms was 56.1% for worker sleeping quarters and 91.1% for apartments. In Dongguan, the treatment rate for worker sleeping quarters, apartments, hotel, and private houses was 90.0, 10.0, 0.0, and 0.0%, respectively.
