Bed Bug

Found globally in human dwellings, particularly in cracks and crevices near sleeping areas such as mattresses, bed frames, and headboards.

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

Mainly nocturnal but may venture out in day to feed if hungry; they undergo hemimetabolous metamorphosis (egg, nymph, adult) and require a blood meal to progress through each of the five nymphal stages.

They do not known to transmit diseases but cause psychological distress, sleep deprivation, and itchy allergic reactions; they are considered a resilient pest with no ecological benefits to human environments.
