Abstract: Objective: The cockroaches in a sauce and pickles factory were investigated and controlled with chemical methods. Method: Density investigation: stickcatch;chemical methods: residual spraying and thermal fogs application. Result: The density index was 4.46 body/box·night. The American cockroaches were the predominant species which rate was 98.97% in the whole captured cockroaches. One week later after application, the density index was 1.29 body/box·night, the killing rate was 71.08%; One month later after application, the density index was 0.93 body/box·night, the killing rate was 79.14%. The adult numbers declined remarkably, but the nymph rate ascended notably. Conclusion: The sauce and pickles factory was encroached seriously by the cockroaches. The chemical methods of residual spraying and thermal fogs application were effective to decrease the cockroaches density.
