大型综合性医院灭鼠方法探讨

Study on the Methods of Deratization in Large Comprehensive Hospitals

目的：探讨适合大型综合性医院防制鼠害有效的措施。方法：用观察法和粉迹法摸清鼠类在医院栖息的最佳场所，根据不同场所鼠密度的高低及投药后鼠药被破坏的难易程度，采取不同的投药方法、投药次数及环境治理综合防制措施。结果：灭鼠后３周灭鼠率达９３．２０％，自灭后４～２６个月内灭鼠率一直保持在９７％～１００％。结论：药物灭鼠与环境治理相结合是最有效的防制方法，采取重点场所灭鼠法可取得事半功倍之效。

Objective:To explore effective methods for rat control in large comprehensive hospitals. Methods: To find out the optimum habitat for rats in hospital with observation and powder tracing methods. And adopt different methods and frequencies for throwing in rodenticides, environmental control, and other comprehensive control measures in accordance with the rat density in different sites and the difficulty of rodenticide destroying after throwing in. Result: The deratization rate reached 93.20 % 3 weeks after deratization and maintained at 97%-100%within 4-26 months after deratization. Conclusion: The combination of rodenticide deratization and environmental control was the most effect, with the adoption of the deratization method in key sites.
