Bed Bug

Found globally indoors in cracks and crevices near their hosts' sleeping areas, such as mattresses, bed frames, and floorboards.

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) requiring a blood meal for each life stage transition and egg production.

Risks include skin rashes, psychological distress, and allergic reactions to bites. They are not known to transmit diseases to humans but cause significant domestic infestations. There are no known benefits to humans or the ecosystem.
