Field-collected bed bugs (Cimex lectularius L.) showed little, if any, adverse effects after 2-h direct exposure to the aerosolized pyrethroid(s) from three over-the-counter total-release foggers ('bug bombs' or 'foggers'); Hotshot Bedbug and Flea Fogger, Spectracide Bug Stop Indoor Fogger, and Eliminator Indoor Fogger. One field-collected population, EPM, was an exception in that there was significant mortality at 5-7 d when bugs out in the open had been exposed to the Spectracide Fogger; mortality was low when these bugs had access to an optional harborage, a situation observed for all field-collected populations when exposed to the three foggers. Even the Harlan strain, the long-term laboratory population that is susceptible to pyrethroids and that served as an internal control in these experiments, was unaffected if the bugs were covered by a thin cloth layer that provided harborage. In residences and other settings, the majority of bed bugs hide in protected sites where they will not be directly contracted by the insecticide mist from foggers. This study provides the first scientific data supporting the position that total-release foggers should not be recommended for control of bed bugs, because 1) many field-collected bed bugs are resistant to pyrethroids, and they are not affected by brief exposure to low concentrations of pyrethrins and/or pyrethroids provided by foggers; and 2) there is minimal, if any, insecticide penetration into typical bed bug harborage sites. This study provides strong evidence that Hotshot Bedbug and Flea Fogger, Spectracide Bug Stop Indoor Fogger, and Eliminator Indoor Fogger were ineffective as bed bug control agents.
野外采集的臭虫（Cimex lectularius L.）在直接暴露于三种市售的全释放喷雾器（“臭虫炸弹”或“喷雾器”）的拟除虫菊酯气溶胶中 2 小时后，几乎没有（如果有的话）不良反应；Hotshot Bedbug and Flea Fogger、Spectracide Bug Stop Indoor Fogger 和 Eliminator Indoor Fogger。一个野外采集的种群 EPM 是一个例外，当在开放环境中暴露于 Spectracide Fogger 时，在 5-7 天时会出现显著的死亡率；当这些臭虫有可选的藏匿处时，死亡率很低，所有野外采集的种群在暴露于三种喷雾器时都观察到了这种情况。即使是 Harlan 株，即对拟除虫菊酯敏感的长期实验室种群，并且在这些实验中作为内部对照，当臭虫被一层薄布覆盖提供藏匿处时，也不会受到影响。在住宅和其他环境中，大多数臭虫隐藏在受保护的地方，它们不会直接接触喷雾器中的杀虫剂雾。这项研究提供了第一个科学数据，支持全释放喷雾器不应该被推荐用于控制臭虫的立场，因为 1）许多野外采集的臭虫对拟除虫菊酯具有抗性，并且它们不会受到喷雾器中提供的低浓度除虫菊酯和/或拟除虫菊酯的短暂暴露的影响；2）杀虫剂进入典型臭虫藏匿处的程度很小，如果有的话。这项研究提供了强有力的证据，表明 Hotshot Bedbug and Flea Fogger、Spectracide Bug Stop Indoor Fogger 和 Eliminator Indoor Fogger 作为臭虫控制剂无效。
