See this bug in the Encyclopedia

Natural Habitat

Hides in mattress seams, bedding, bed frames, and nearby cracks; the insects and cast skins shown on fabric are consistent with an infestation.

Diet & Feeding

Feed exclusively on blood, usually from people, most often at night.

Behavior Patterns

Flat, wingless insects that hide in groups and emerge to feed. Nymphs molt several times, leaving pale, empty skins.

Risks & Benefits

Bites can cause itchy welts and allergic reactions, and infestations can be stressful; bed bugs are not known to transmit disease. Limited image detail means identification is not definitive.
