The common bedbug (Cimex lectularius) is increasingly prevalent and a source of concern and questions for patients. In addition to a range of cutaneous presentations and potential for serious sequelae, bedbug bites cause significant psychological distress and create an economic burden associated with infestation control. Recognition of characteristic entomology, clinical presentation, diagnostic features and differential diagnosis can support expedient identification of patients exposed to infestations and support their appropriate management.
