Objective To discuss the degree of cockroaches invasion in hospital, and formulate the control measures. Methods Investigating cockroaches invasion situation by eye and using insecticide trap method, using glue trap to determine the density of cockroaches. Results The invasion rate of cockroaches adult and nymph was 10.27% which was three times more than the national standard. 73% departments exceeded the provided standard, neurosurgery and general surgery department reached nearly 7 times. The positive density index was 12.02 pieces per room. The egg positive rate was 2.74% which exceeded the national standards. Two kinds of cockroaches were investigated, they were Blattella germanica （55.3%） and Periplaneta japonica（ 44. 7% ）. Conclusion The invasion sit- uation of cockroaches is serious in hospitals. It is necessary to control cockroaches and eliminate breeding ground combined with environmental features
