Bed Bug

Found globally in human dwellings, particularly 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 and reproduce.

Risks include itchy skin welts, allergic reactions, psychological distress, and secondary infections from scratching. They are not known to transmit diseases to humans but are considered a significant public health pest.
