Bed Bug

Found globally in human dwellings, typically residing in mattress seams, bed frames, headboards, and cracks or crevices near sleeping areas.

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans. The reddish color in the image indicates a recent blood meal.

Nocturnal insects that emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to molt to the next life stage.

They do not transmit diseases but cause psychological distress, skin rashes, and allergic reactions from bites. They are considered a significant public health pest due to the difficulty and cost of eradication.
