Bed Bug

Indoor environments, primarily in cracks and crevices near human sleeping areas such as mattresses, bed frames, and headboards.

Obligate hematophagous (blood-fed); they primarily feed on the blood of humans, though they may bite other warm-blooded animals.

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis with five nymphal stages, each requiring a blood meal to molt.

Risks: Causes itchy welts, allergic reactions, insomnia, and psychological distress. While they carry pathogens, they are not known to transmit diseases to humans. Benefits: None to the indoor ecosystem; considered a major household pest.
