We conducted a door-to-door survey in a residential census tract of Philadelphia to estimate the prevalence and spatial patterns of recent bed bug infestations. We interviewed 596 residents, of whom 66 (11.1%) reported recent bed bug infestations. We confirmed current infestations in a subset of 15 (68.2%) of 22 inspected households. Most residents reported that their infestation began within the past year (2012-2013). We found no correlation between property value and infestation status. Spatial analyses showed significant clustering of bed bug infestations only at fine scales, suggesting limited active dispersal of the insects. Residents used a large variety of treatment methods to eliminate bed bugs, but only 48.1% reported success. Our results provide a prevalence estimate of recent bed bug infestations and highlight the importance of passive rather than active dispersal of bed bugs even among dense urban row homes.
我们在费城的一个居民普查区进行了挨家挨户的调查，以估计近期臭虫侵扰的患病率和空间分布模式。我们采访了596名居民，其中66人（11.1%）报告近期有臭虫侵扰。我们在22户接受检查的家庭中的15户（68.2%）中确认了当前的侵扰情况。大多数居民报告说，他们的侵扰始于过去一年（2012 - 2013年）。我们发现房产价值与侵扰状况之间没有关联。空间分析表明，臭虫侵扰仅在精细尺度上存在显著聚类，这表明臭虫的主动扩散有限。居民使用了各种各样的处理方法来消灭臭虫，但只有48.1%的人报告成功。我们的结果提供了近期臭虫侵扰的患病率估计，并强调了即使在密集的城市排屋中，臭虫被动而非主动扩散的重要性。
