Abstract: Objective To investigate the infestation of bed bugs in China, and to provide a scientific basis for risk assessment and effective prevention and control of bed bugs. Methods The bed bug surveillance data were collected from the National vectors Surveillance in China in 2018. The occurrence of bed bug infestation was compared between different provinces or habitats. Results Bed bug surveillance was carried out in 13 provinces (autonomous regions, centrally administered municipalities) via field investigation and telephone survey. A total of 1 537 units were investigated on site, of which 11 had bed bug, infestation giving a positive infestation rate of 0.72%. A total of 17 332 standard rooms were investigated; among them, 31 (0.18%) had bed bugs. The habitats with the highest positive rates, in sequence, were dormitories in construction site, student dormitories, residential areas, nursing homes, and hotels. Conclusion Bed bugs are widely distributed in China, and the density of bed bugs in most areas was still at a relatively low level. The results of investigation indicated that construction site dormitories, residential areas, and student dormitories are the foci of bed bug infestation surveillance in the future.
