In some individuals, psychological sequelae resulting from bed bug biting events include nightmares, flashbacks, hypervigilance (to keep the bugs away), insomnia, anxiety, avoidance behaviors, and personal dysfunction. These symptoms are suggestive of posttraumatic stress disorder (PTSD).
We used a previously published PTSD checklist to analyze online blogs and other Internet sites where bed bug postings occur to assess postings for evidence of emotional trauma.
One hundred thirty-five postings were read and analyzed, and 110 (81%) of those postings reported psychological effects from bed bug infestations. Scoring with the PTSD checklist revealed a range of 0-52 (mean 13.25; SD 9.38); one met the criteria (≥50) considered positive for PTSD.
Based upon our survey of online postings concerning such effects, an as-yet-to-be-determined proportion of individuals who experience bed bug bites develop moderate-to-severe negative emotional symptoms after infestations. These individuals should be identified in the course of their interactions with health professionals so that appropriate mental health care may be provided.

    • "After feeding, they defecate and leave black or brown spots, the typical signs of bedbug infestation [9]. Although bedbugs are not in as insect vector of diseases, they reduce the quality of life by causing discomfort, anxiety, insomnia, ostracism , psychological disorders or various phobias [2] [10]. The victims have often been reported to suffer from biting and a variety of cutaneous and systemic reactions [10] [11]. "

    ABSTRACT: Over the past decade, a dramatic rise in bedbug resurgence has become one of the top potential public health hazards. This study was conducted to determine prevalence, knowledge and self-reported containment practices about bedbugs in the resource-limited setting of Ethiopia. A community based, cross-sectional survey was conducted between January and May 2014. Selected 260 respondents were interviewed by the administration of a pre-tested questionnaire on knowledge and practices about bedbug infestation in the resource-limited setting of Ethiopia. Overall, 91.6% (238/260) of the residents had ample awareness on bedbug infestation. The majority of them (97.2%) extremely bothered about infestations because of bad odors (83.8%), insomnia (79.8%), biting (66.9%), and skin rashes (56.9%). A high prevalence of infestation (72.7%) was observed. Bedrooms and main hall/salon were identified as potential high-risk areas. Chi-square exhibited a strong association between sanitary status and housing conditions (χ2 = 40.91; df = 4; P = 0.0001). Besides, there was a strong association between respondents’ monthly income (χ2 = 42.1; df = 6; P = 0.0001) and educational status (χ2 = 26.01; df = 5; P = 0.0001) with the presence or absence of bedbug infestation. Though the majority of respondents had adequate knowledge, they suffer with deprived practices attributable to deficient resources as well as negligence/ignorance. This study emphasizes the following key interventions: 1) community-based awareness campaigns, 2) implementation of sustainable preventive/containment strategies, 3) educational interventions to ensure translation of knowledge into practices, and 4) the implementation of appropriate poverty alleviation programs to enhance the local-residents living-standard in the future.

    • "Chronic blood loss and iron deficiency anemia have also been reported in people who have been continuously exposed to severe bed bug infestations (Venkatachalam and Belavady, 1962; Pritchard and Hwang, 2009; Paulke-Korinek et al., 2012). Bed bugs can also cause psychological disorders because the presence of these insects in intimate places such as beds and bedrooms often creates anxiety, and people who are repeatedly bitten may develop nervous behavior, agitation, stress and sleeplessness (Hwang et al., 2005; Goddard and de Shazo, 2012; Susser et al., 2012). The adverse effects of bed bugs on humans have "

    ABSTRACT: Many hematophagous arthropods are stimulated by blood constituents to initiate feeding. We used a membrane-based feeding system to identify chemicals that stimulate acceptance and engorgement responses in various life stages of bed bugs. Water was fortified with a variety of compounds (e.g. salts, amino acids, vitamins, nucleotides, cholesterol and fatty acids) in these bioassays. Adenosine triphosphate was the most effective phagostimulant in adults and nymphs, resulting in >70% of bed bugs fully engorging. Addition of NaCl to low ATP solutions that alone elicited <50% engorgement significantly enhanced feeding responses of bed bugs. A comparison of feeding responses with solutions of various adenine nucleotides showed that ATP was more stimulatory than ADP, which was more effective than AMP. Feeding assays with physiological levels of other blood constituents such as D-glucose, albumin, globulin, cholesterol and mixtures of vitamins and amino acids did not stimulate engorgement, suggesting that adenine nucleotides are the most important feeding stimulants in bed bugs. Identification of phagostimulants for bed bugs will contribute toward the development of artificial diets for rearing purposes as well as for the development of alternative methods to eliminate bed bug infestations.

    • "Our report of an isolated case history, together with the published case series [4] and review of blogs and other internet sites [6], provides evidence that bed bugs are a severe stressor and can result in serious and life-threatening psychiatric consequences for those that are vulnerable. Given the recent surge in infestations in many different cities, rapid action needs to be taken not only in an attempt to control and eradicate the bed bugs but also to adequately care for the individuals affected.

    ABSTRACT: Male, 62. Bipolar disorder. Bordeline personality disorder. - Bed bug infestation. Psychiatry. Unusual clinical course. In the past decade, bed bug infestations have been increasingly common in high income countries. Psychological consequences of these infestations are rarely examined in the scientific literature. We present a case, based on a coroner's investigation report, of a woman with previous psychiatric morbidity who jumped to her death following repeated bed bug infestations in her apartment. Our case report shows that the bed bug infestations were the likely trigger for the onset a negative psychological state that ultimately led to suicide. Given the recent surge in infestations, rapid action needs to be taken not only in an attempt to control and eradicate the bed bugs but also to adequately care for those infested by bed bugs.
