Objective: To understand the hazards of cockroach in upscale hotels in Beijing and provide basis for prevention and control. Methods: Four four-star hotels and four five-star hotels were selected, and the density was measured by the stick-catching method. Results: The density of cockroaches in 8 restaurants was 0.15 ~ 14.31 per day (average only 4.21), higher than the average density of the city in the same period. The average density of 4 4 - star hotels (5. 71) was higher than 4 five-star hotels (2.67); the infringement sites were most serious with noodles (9.17), western operation rooms (5.77) and cold intercourse rooms (5.45). Conclusion: The cockroach infringement in upscale restaurants can not be ignored, and should be effectively controlled.
