Bedbugs do not inhabit or live on humans. Rather, they tend to inhabit cracks and crevices of mattresses, cushions, bed frames, or other structures. Bedbugs are attracted to the host by warmth and carbon dioxide and generally feed at night while the victim sleeps. Skin reactions to bedbugs vary, ranging from no reaction to pruritic papules or wheals, purpuric macules, or bullae. Reactions are typically noticed upon awakening or within a few days after the bites.
Management: Pest control (application of insecticides and heat treatment). Bedbug bites resolve spontaneously. Topical corticosteroids and oral antihistamines may reduce associated pruritus.
