Over the last two decades, an increase in bed bug infestations has been observed worldwide. Although their definitive role as vectors of infectious agents has not yet been demonstrated, bed bugs have a direct effect on human health through dermatological reactions to their bites and psychological disorders linked to domestic infestations. In this study, the effectiveness of using MALDI-TOF MS to correctly identify these two bed bug species at immature stages was assessed, as well as it effectiveness as discriminating between the immature stages (IS) of C.

Scabies, Bedbug, and Body Lice Infestations: A Review.

JAMA

September 2024

Department of Dermatology, University of California, San Francisco, School of Medicine, San Francisco.

Article Synopsis
  • Scabies, bedbugs, and body lice are skin infestations caused by various organisms, leading to itching and rashes, with scabies cases reaching about 622 million globally in 2021, while body lice prevalence varies significantly among homeless individuals.
  • Scabies is caused by mites that burrow into the skin and is primarily spread through prolonged skin-to-skin contact; effective treatments include permethrin cream and oral ivermectin, though some treatment failures can occur.
  • Bedbugs feed on blood while people sleep, causing itchy welts, while body lice live in clothing and lead to similar skin irritations; treatment generally involves good hygiene practices and pest management for eradication.

Characterization of the common bed bug's eggshell and egg glue proteins.

Int J Biol Macromol

September 2023

School of Systems Biomedical Science and Integrative Institute of Basic Sciences, Soongsil University, Seoul 06978, Republic of Korea. Electronic address:

Article Synopsis
  • Insect eggs, especially those of the common bed bug, require protective shells and glues for successful development, and the study focuses on these proteins.
  • Researchers identified a specific protein that acts as egg glue, using advanced techniques like mass spectrometry and RNA interference.
  • The findings suggest that targeting these egg proteins could lead to new, species-specific methods for controlling bed bug populations, addressing their growing resistance to pesticides.

Article Synopsis
  • - Bed bug infestations have surged globally, necessitating awareness and proper identification for effective treatment and eradication.
  • - Bed bug bites are usually painless, presenting as itchy, red bumps that can appear in clusters or a linear pattern, with specific features suggesting bed bug activity.
  • - Treatment is mainly symptomatic, involving antihistamines and topical corticosteroids, alongside integrated pest management strategies that include cleaning, monitoring, and both nonchemical and chemical interventions for eradication.

Article Synopsis
  • * In laboratory tests, the treated fabric showed a 56.6% repellency against bed bugs and over 80% mortality rate for mosquitoes, maintaining effectiveness even after 20 wash cycles.
  • * Analyses indicated that despite some decrease in insecticide content after washing, the fabric remained effective, and tests confirmed it retained sufficient insecticides and maintained its structural integrity.

Article Synopsis
  • * Conducted across 86 wards in two hospitals, the study found that 72.1% had signs of bedbug presence, with a notably lower rate in wards that had control measures in place (25.8% versus 74.2%).
  • * The study concluded that there is a high prevalence of bedbug infestations in the hospitals examined and that ward supervisors lack adequate knowledge about pest identification and effective eradication methods.

Bedbugs: how to diagnose and manage cases of infestations.

Clin Exp Dermatol

April 2023

Department of Dermatology, St Mary's Hospital, Portsmouth University Hospital NHS Trust, Portsmouth, UK.

Article Synopsis
  • Bedbugs are increasing in urban areas globally, potentially due to bans on certain pesticides.
  • They are flat insects that primarily feed on human blood, and their bites are typically non-toxic, making them hard to detect but can lead to various skin reactions.
  • Effective eradication of bedbugs usually involves a combination of physical methods, like high temperatures and traps, and chemical treatments that include specific insecticides.

Article Synopsis
  • Bed bugs, specifically Cimex lectularius, have re-emerged in poultry farms due to the decline of DDT and organophosphates, posing potential health risks to chickens such as stress and anemia.
  • The study tested two veterinary drugs, ivermectin and fluralaner, for their effectiveness against bed bugs, using both an artificial feeding system and actual chickens with different treatment methods.
  • Results showed that fluralaner significantly reduced bed bug populations even in resistant strains, while ivermectin was ineffective in chickens but fluralaner proved successful for up to 28 days post-treatment, indicating a promising approach for controlling bed bug infestations in poultry.

Perspective on Biology and Management of Bed Bugs: Introduction.

J Econ Entomol

February 2023

Fort Lauderdale Research and Education Center, University of Florida, Davie, FL 33314, USA.

Article Synopsis
  • Bed bugs are significant medical and urban pests that feed on blood, causing skin irritations, allergic reactions, and potential mental health issues.
  • They disproportionately affect low-income communities due to the high cost of effective control methods, allowing infestations to spread throughout society.
  • A collection of research papers has been compiled to explore various aspects of bed bug management, aiming to inspire future studies on safer and more cost-effective treatment options.

Article Synopsis
  • Infective endocarditis, a serious infection of the heart, can arise from normal skin bacteria and is linked to high mortality rates.
  • A case study detailed a 48-year-old woman with no major health issues who developed bacteremia and endocarditis after presenting with skin lesions from bed bug bites.
  • The study highlights the suspected connection between bed bug bites and bacteremia, noting that while bed bugs can carry pathogens, their role as a vector for such infections has not been established in previous literature, making this case unique.

Article Synopsis
  • Papular urticaria is a skin reaction caused by insect bites, especially from bugs like bedbugs and mosquitoes.
  • In a study with 20 kids who had this problem from bedbugs, some received a special treatment called immunotherapy, while others got regular treatment for a year.
  • The kids who had immunotherapy reported much less itching and better quality of life compared to those who had the regular treatment.

Bedbug salivation patterns during hematophagy in the skin of a mammalian host.

J Insect Physiol

September 2021

Laboratório de Fisiologia de Insetos Hematófagos, Departamento de Parasitologia/ICB, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil. Electronic address:

Cimex lectularius (Hemiptera:Cimicidae) infestations have increased over the past decades in several parts of the world, constituting a major urban pest with no reversion signs. The impact on human health caused by these insects, commonly known as bedbugs, is associated with their obligatory hematophagous habit. Allergies induced by hematophagous arthropod bites are related to the deposition of salivary molecules in the host tissues.
