Bed Bug

Found globally in human dwellings, particularly in cracks, crevices, bed frames, mattresses, and upholstered furniture.

Obligate hematophages, meaning 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 advance to the next life stage.

Risks include itchy welts, allergic reactions, and psychological distress. While they carry various pathogens, they are not known to transmit diseases to humans. There are no ecological benefits to humans; they are considered a significant pest.
