目的：验证杀它仗在特殊环境的灭鼠效果，探索适当的应用技术。方法：常规灭鼠试验方法。以鼠迹法测定鼠密度，据此计算灭效。结果：特殊环境杀它仗灭鼠试验分３个阶段：第１阶段用杀它仗蜡块、切麦等成品毒饵，在医院、饭店、养鸡场分别取得８７．７４％、９１．３９％、８６．６７％的灭效；第２阶段用杀它仗母粉临时配制的毒水及水果、面包渣、玉米面等毒饵，医院、饭店的灭效进一步提高到９８．８２％、９８．０７％。第３阶段在医院、饭店采取环境改造、改善卫生状况、防鼠等措施，灭效分别达到１００％、９９．１４％。４个月后跟踪调查，医院、饭店、养鸡场的鼠密度分别回升到０．３８％、０．８５％、１３．８９％。养鸡场由于缺少第２、３阶段，４个月后鼠害已非常严重。结论：杀它仗对鼠类有良好的适口性，在特殊环境灭鼠效果良好；采取环境治理与防鼠等配套措施，可增强灭效，延缓鼠类种群的恢复。
Objective: To verify the anti-rodent effect of killing it in special circumstances and to explore appropriate application techniques. Methods: Conventional rodent control test methods. Mouse density was measured by mouse trace method, and then calculated to be effective. Results: The special environment to kill its antiseptic test is divided into three stages: the first stage to kill its wax block, cut wheat and other finished bait, in hospitals, restaurants, chicken farm were made 87.74%, 91.39% , 86.67% of the dead; the second phase to kill its mother fortune temporary preparation of poisonous water and fruit, bread crumbs, cornmeal and other baits, hospitals, restaurants to further increase the effectiveness of 98.82%, 98.07 %. Stage 3 In hospitals and restaurants, environmental improvement, health improvement and rodent control measures were taken to eliminate 100% and 99.14% respectively. After 4 months of follow-up investigation, the rat density in hospitals, restaurants and chicken farms rose to 0.38%, 0.85% and 13.89% respectively. Due to the lack of stages 2 and 3 of the chicken farms, the rodents have become very serious after 4 months. Conclusion: Kill its battle against mice has good palatability, rodent control in special circumstances good effect; to take environmental governance and anti-rat and other ancillary measures to enhance the effectiveness of extinction, delaying the recovery of rodents.
