Bed Bug

Domestic environments, specifically in cracks and crevices of furniture, mattresses, and bed frames near sleeping hosts.

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans.

Mainly nocturnal; they emerge from hiding at night to feed and exhibit a characteristic 'breakfast, lunch, and dinner' bite pattern in a linear row.

Risks include itchy, red welts, secondary skin infections from scratching, and psychological distress; they are not known vectors of infectious diseases to humans.
