A total of 213 rats were obtained, belonging to 3 genera and 5 species; 294 fleas, belonging to 2 genera and 2 species. With 0.05% of the enemy rat poisoning sodium poisoning Valley saturation, made 96% of the anti-rat effect, immediate control of the outbreak, indicating that the emergency treatment of plague outbreaks should be the preferred chronic rodenticide. With 0.05% deltamethrin and 5% DDT plus 0.5% dichlorvos mixture, respectively, before and after decontamination on the ground for stranded spray, the flea-killing rate was 93%; and only 5% DDT plus 0.5% dichlorvos before delustering Spraying once, the flea-killing rate was only 74%, I analyzed the reason.
