Bed bug resistance to commonly used pesticide sprays has led to exploring new pesticides and other strategies for bed bug management. Non-chemical methods are effective in bed bug management; however, they do not provide residual protection. Compared to insecticide sprays, dust formulations are considered to provide longer residual control. We evaluated two bed bug management programs in apartment buildings. A building-wide inspection was initially conducted to identify bed bug infested apartments. Selected apartments were divided into two treatment groups: non-chemical plus silica gel dust treatment (10 apartments) and non-chemical treatment (11 apartments). After initial treatment, apartments were re-visited monthly for up to 6 months. During each visit, the total bed bug count per apartment was obtained by examining interceptor traps placed in the apartments and conducting a visual inspection. Mean bed bug count was reduced by 99% and 89% in non-chemical plus silica gel dust and non-chemical treatment, respectively. Non-chemical plus silica gel dust treatment caused significantly higher bed bug count reduction than the non-chemical treatment at 6 months. Bed bugs were eradicated from 40% and 36% of apartments treated with non-chemical plus silica gel dust treatment and non-chemical treatment, respectively.
臭虫对常用杀虫剂喷雾产生抗性，促使人们探索新的杀虫剂及其他臭虫治理策略。非化学方法在臭虫治理中有效；然而，它们无法提供残留防护。与杀虫剂喷雾相比，粉尘制剂被认为能提供更长时间的残留防治效果。我们在公寓楼中评估了两种臭虫治理方案。首先进行全楼检查，以确定有臭虫侵扰的公寓。选定的公寓被分为两个处理组：非化学方法加硅胶粉尘处理组（10套公寓）和非化学方法处理组（11套公寓）。初次处理后，每月对公寓进行复查，为期长达6个月。每次复查时，通过检查放置在公寓内的拦截器陷阱并进行目视检查，统计每套公寓内臭虫的总数。非化学方法加硅胶粉尘处理组和非化学方法处理组的臭虫平均数量分别减少了99%和89%。在6个月时，非化学方法加硅胶粉尘处理组导致的臭虫数量减少幅度显著高于非化学方法处理组。分别有40%和36%接受非化学方法加硅胶粉尘处理和非化学方法处理的公寓内臭虫被根除。
