Bed bug (Cimex lectularius L.) infestations are currently controlled by a variety of non-chemical and chemical methods. There have been few studies on the comparative effectiveness of these control techniques. We evaluated three bed bug management strategies in an apartment building: (1) non-chemical methods only (n = 9); (2) insecticides only (n = 6); and (3) integrated pest management including both non-chemical methods and insecticides (n = 9). The apartments were one-bedroom units occupied by seniors or people with disabilities. Bed bug numbers in each apartment were determined by visual inspection and/or installing intercepting devices under bed and sofa legs. The median (min, max) bed bug counts in the non-chemical methods only, insecticides only, and integrated pest management (IPM) treatment were: 4 (1, 57), 19 (1, 250), and 14 (1, 219), respectively prior to the treatments. The apartments were retreated if found necessary during biweekly to monthly inspections. After 10 weeks, bed bugs were found to be eliminated from 67, 33, and 44% of the apartments in the three treatment groups, respectively. The final (after 10 weeks) median (min, max) bed bug counts in the non-chemical methods only, insecticides only, and IPM treatment were: 0 (0, 134), 11.5 (0, 58), and 1 (0, 38), respectively. There were no significant differences in the speed of bed bug count reduction or the final bed bug counts. Lack of resident cooperation partially contributed to the failure in eliminating bed bugs from some of the apartments. Results of this study suggest that non-chemical methods can effectively eliminate bed bugs in lightly infested apartments.
臭虫（温带臭虫）的侵扰目前通过多种非化学和化学方法进行控制。关于这些控制技术的比较有效性的研究很少。我们在一栋公寓楼中评估了三种臭虫管理策略：（1）仅采用非化学方法（n = 9）；（2）仅使用杀虫剂（n = 6）；以及（3）包括非化学方法和杀虫剂的综合虫害管理（n = 9）。这些公寓是一居室单元，居住者为老年人或残疾人。通过目视检查和/或在床腿和沙发腿下安装拦截装置来确定每个公寓中的臭虫数量。在处理之前，仅采用非化学方法、仅使用杀虫剂以及综合虫害管理（IPM）处理的公寓中臭虫数量的中位数（最小值，最大值）分别为：4（1，57）、19（1，250）和14（1，219）。如果在每两周至每月一次的检查中发现有必要，就对公寓进行再次处理。10周后，在三个处理组中，分别有67%、33%和44%的公寓中的臭虫被消灭。仅采用非化学方法、仅使用杀虫剂以及IPM处理的最终（10周后）臭虫数量中位数（最小值，最大值）分别为：0（0，134）、11.5（0，58）和1（0，38）。在臭虫数量减少的速度或最终臭虫数量方面没有显著差异。居民缺乏合作在一定程度上导致了一些公寓未能消灭臭虫。这项研究的结果表明，非化学方法可以有效地消灭轻度侵扰公寓中的臭虫。
