Bed Bug

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

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

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to molt.

Risk: Causes itchy bites and potential allergic reactions; significant psychological distress and sleep deprivation. Benefit: None; they are considered a major public health pest.
