Bed Bug

Found worldwide in human dwellings, typically nesting in cracks, crevices, mattress seams, and baseboards near sleeping areas.

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans.

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

They do not transmit diseases but their bites can cause allergic reactions, skin rashes, psychological distress, and sleeplessness. They have no known benefits to humans or ecosystems.
