Bed Bug

Indoor environments, specifically in close proximity to human sleeping areas such as mattresses, bed frames, and furniture cracks.

Obligate hematophages, primarily feeding on human blood, though they may also feed on other warm-blooded animals.

Nocturnal parasites that hide in tight crevices during the day; they detect hosts through heat and carbon dioxide and undergo incomplete metamorphosis with five nymphal stages.

They are a significant public health pest causing itchy welts, psychological distress, and potential allergic reactions; they have no known ecosystem benefits in domestic settings.
