Abstract: Objective To investigate an incident of bedbug infestation in a passenger train in Wuhan, China, manage the incident by emergency disposal, and observe the control effects continually, and to provide a basis for scientific emergency disposal methods and effective control measures for bedbug infestation in passenger train. Methods Visual inspection, needle picking, and pesticidal stimulation were used to investigate the bedbug infestation in the passenger train. The control effects were observed for 2 consecutive years. Results The bedbug infestation rate was 2.59%, and the infestation was concentrated in the couchettes (100%), mostly distributed at the lower berths (66.67%) and hidden in the gaps between bed boards and board walls. Scientific disposal methods and long-term control measures were taken accordingly and achieved reliable and durable control effects. Conclusion The bedbugs were brought into the passenger train, and control measures should focus on the couchettes. The emergency disposal should be early, careful, and strict and well implemented. Long-term effective control measures are fundamental for preventing bedbugs in passenger train．
