Bed Bug

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

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

Nocturnal and elusive; they emerge from hiding at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive months without a meal.

Risks include itchy skin welts, allergic reactions, and psychological distress/insomnia. While they do not efficiently transmit diseases, infestations are difficult and costly to eradicate.
