Bed Bug

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

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

Mainly nocturnal pests that emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive for several months without a blood meal.

Risks include itchy allergic reactions to bites, psychological distress, and sleep deprivation. While they do not reliably transmit diseases, they are difficult and expensive to eradicate from homes.
