目的研究城市居民区住宅外灭鼠对住宅家栖鼠侵害率的影响;探讨在住宅外全面灭鼠的基础上进行室内灭鼠的控制效果。方法外环境鼠洞采用堵洞投饵法;普通地面采用裸投稻谷毒饵法;下水道、化粪池及垃圾通道采用挂蜡块法;室内采用逐户调查,每周1次,共5次免费送鼠药灭鼠,并宣传灭鼠方法。结果居民区外环境鼠洞、普通地面、下水道、化粪池及垃圾通道灭效均为100%;而住宅外灭鼠试验前后居民住宅家栖鼠侵害率分别为26.0%和18.5%,最后一次入户为2.8%,住宅外灭鼠对住宅家栖鼠侵害率控制效果为28.7%,而免费送药灭鼠后住宅家栖鼠控制效果为89.1%。结论居民区住宅内外同时采取有效的灭鼠措施,能使居民区鼠密度控制在较低水平。
Objective To study the impact of rodent deratization on residential home rats in residential areas in urban areas and on the control effects of indoor rodent control on the basis of complete rodent control outside residential areas. Methods The external environment mousehole was blocked by the plugging hole method. The common ground was covered with naked rice bait method. The sewer, septic tank and garbage channel were hung by wax method. The indoor investigation was carried out on a household-by-household basis once per week for 5 times Send rodenticide rodent, and promote rodent control methods. Results The outbreaks of rat, common ground, sewer, septic tank and litter in residential areas were both 100% effective, while the domestic resident rodent infestation rates were 26.0% and 18.5% before and after the out-of- The average home ownership was 2.8%. Out-of-home rodent control was 28.7% of the domestic home-rodent infestation rate. However, the control effect of domestic rodents was 89.1% after the free rodent control. Conclusion Residential area both inside and outside the house to take effective rodent control measures, can make residential area density control at a low level.
