Natural Habitat
Indoor sleeping areas, especially mattress seams, bed frames, upholstery, and cracks near resting places.
Diet & Feeding
Feeds exclusively on blood, primarily from humans, using piercing-sucking mouthparts. It usually feeds at night.
Behavior Patterns
Wingless, flattened, and nocturnal; hides in crevices during daylight and molts through five nymphal stages. Populations can persist for months without feeding.
