Bed Bug

Indoor environments, specifically cracks and crevices near sleeping areas such as mattresses, bed frames, and upholstered furniture.

Obligate hematophages, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans. The image appears to show a bug that has been crushed after a blood meal.

Nocturnal parasites that hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (nymph to adult) and can survive for months without feeding.

Risk: They cause itchy, red welts through their bites and can cause significant psychological distress and secondary skin infections from scratching. Benefit: None; they are considered a major domestic pest.
