Bed Bug

Found globally in human dwellings, typically hiding in mattress seams, bed frames, cracks, and crevices near sleeping areas.

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

Mainly nocturnal and elusive. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to transition between each developmental stage.

Risks include itchy skin rashes, psychological distress, and allergic reactions to bites. They are not known to transmit diseases to humans but are considered a significant public health pest.
