Bed Bug

Human dwellings, specifically in cracks and crevices near sleeping areas such as mattresses, bed frames, and headboards.

Obligate hematophagous (blood-eaters), primarily feeding on human blood, though they may bite other mammals or birds.

Nocturnal parasites that hide during the day and emerge at night; they undergo hemimetabolous metamorphosis, passing through five nymphal stages that each require a blood meal to molt.

Risks include itchy allergic reactions to bites, sleep deprivation, and psychological distress. While they are not known to transmit diseases to humans, they are a significant domestic pest requiring professional extermination.
