Bed Bug

Indoor environments, specifically within human dwellings, nesting in mattress seams, bed frames, cracks, and crevices near sleeping areas.

Hematophagous (obligate blood-feeders), primarily consuming human blood but sometimes feeding on other warm-blooded animals.

Nocturnal and elusive; they remain hidden during the day and emerge at night to feed. They undergo a hemimetabolous life cycle involving five nymphal stages, each requiring a blood meal to molt.

Risks include itchy skin rashes, psychological distress, and allergic reactions to bites; they are not known vectors of disease. There are no ecological benefits to humans.
