Rodents are responsible for the transmission of more than 60 diseases both to human beings and to domestic animals. The increase in rodent infestation in a given area brings several health problems to the nearby population. Thus, when infestation increases, it is time to take intervention measures. Although many countries have implemented programs aimed at controlling rodent infestation, literature on studies evaluating the effectiveness of intervention measures in urban areas is scarce. Aimed at contributing to the understanding of rodents' population dynamics in urban areas, the objective of this study was to evaluate the effectiveness of the control methods proposed by "Programa de Vigilancia e Controle de Roedores do Municipio de Sao Paulo" (Program for Rodents Surveillance and Control in Sao Paulo Municipality), conducted on Jardim Comercial District. As a first step, a survey to assess infestation rates was conducted in 1529 dwellings located in the area studied. After that, a chemical control upon rodents was accomplished in every dwelling infested. One week and six months after completion of control measures, a new evaluation on infestation rates was carried out, in order to verify the effectiveness of the procedures taken and to estimate the re-infestation capacity. Initial infestation rate was 40.0%, and the final infestation rate, 14.4%. Therefore, the effectiveness of the control methods utilized was 63.8%. It can thus be concluded that the control methods applied were quite effective.
啮齿动物可传播 60 多种疾病给人类和家畜。在特定地区，啮齿动物的滋生会给附近的人口带来许多健康问题。因此，当滋生增加时，就需要采取干预措施。尽管许多国家已经实施了旨在控制啮齿动物滋生的计划，但关于评估城市地区干预措施有效性的文献却很少。本研究旨在评估“圣保罗市啮齿动物监测和控制计划”（Sao Paulo 市啮齿动物监测和控制计划）提出的控制方法在商业花园区的有效性，为理解城市地区啮齿动物的种群动态提供帮助。作为第一步，对研究区域内的 1529 处住所进行了一项评估滋生率的调查。之后，对所有有啮齿动物滋生的住所进行了化学控制。在完成控制措施一周和六个月后，对滋生率进行了新的评估，以验证所采取措施的有效性，并估计再次滋生的能力。初始滋生率为 40.0%，最终滋生率为 14.4%。因此，所使用的控制方法的有效性为 63.8%。可以得出结论，应用的控制方法非常有效。
