The common bed bug ( Hemiptera; Cimicidae) infests homes and service industries, and the number of infestations has greatly increased over the past 20 years. At present, no cost-effective control methods are available, and eradication programs are expensive and laborious. We investigated the control potential of desiccant dust in combination with CO as a bed bug activity stimulant. An initial experiment with two desiccant dusts was followed by arena studies with varying doses, available hiding places and the presence or absence of host signals. Finally, we conducted a field experiment with Syloid 244FP with or without CO gas. Syloid was superior compared to diatomaceous earth, and effective at the concentration of 1.0 g/m in the field experiment. The number of harborages and partial application of desiccant dust decreased mortality in the laboratory. Bed bug activation by CO appeared of minor importance in the arena studies, but was crucial for the eradication in the student dormitories. In fact, all 5 bed bug-infested dormitories with a combined treatment of desiccant dust and CO were freed of bed bugs, whereas eradication was not successful in any of the 6 dormitories with only desiccant dust treatment. The different results in the laboratory and field experiment were most likely caused by the longer activation and higher dose of CO used in the field experiment than the laboratory experiment. Our study showed that application of desiccant dust in combination with release of CO gas to mimic human presence is a promising option for bed bug control.
普通臭虫（半翅目；臭虫科）侵扰家庭和服务业，在过去20年里，侵扰数量大幅增加。目前，尚无经济有效的控制方法，根除计划成本高昂且费力。我们研究了干燥剂粉尘与一氧化碳作为臭虫活动刺激剂相结合的控制潜力。最初对两种干燥剂粉尘进行了实验，随后进行了场地研究，涉及不同剂量、可用藏身之处以及宿主信号的有无。最后，我们对有或没有一氧化碳气体的Syloid 244FP进行了现场实验。在现场实验中，Syloid比硅藻土更有效，在浓度为1.0克/立方米时有效。在实验室中，藏匿处数量和干燥剂粉尘的局部应用降低了死亡率。在场地研究中，一氧化碳对臭虫的激活作用似乎不太重要，但对学生宿舍的根除至关重要。事实上，所有5个同时接受干燥剂粉尘和一氧化碳联合处理的臭虫侵扰宿舍都清除了臭虫，而6个仅接受干燥剂粉尘处理的宿舍均未成功根除。实验室和现场实验结果不同，最可能的原因是现场实验中使用的一氧化碳激活时间更长、剂量更高，而实验室实验并非如此。我们的研究表明，应用干燥剂粉尘并释放一氧化碳气体以模拟人类存在是控制臭虫的一个有前景的选择。
