Bed Bug

Human dwellings, specifically beds, mattress seams, furniture, and wall crevices

Obligate hematophages, feeding primarily on human blood at night

Nocturnal, hiding in dark crevices during the day and attracted to host heat and carbon dioxide during the night

Risks include itchy bites, allergic reactions, secondary skin infections, and significant psychological distress from infestations; they provide no ecosystem benefits in domestic settings
