Common Bed Bug (crushed)

Found globally in human dwellings, typically hidden in mattresses, bed frames, cracks, and crevices near sleeping areas.

Obligate hematophages, meaning they feed exclusively on animal blood, primarily from humans.

Nocturnal and elusive; they emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult). When crushed after feeding, they leave a distinct reddish-brown blood stain as seen in the image.

Risks include itchy skin rashes, psychological distress, and allergic reactions. They are not known to transmit diseases to humans. There are no known benefits to the ecosystem in a domestic setting.
