Bed Bug

Found globally in human dwellings, typically nesting in mattress seams, bed frames, cracks, crevices, and behind wallpaper in sleeping areas.

Obligate hematophages, meaning they feed exclusively on animal blood, primarily from humans, using a piercing-sucking mouthpart.

Nocturnal insects that emerge at night to feed. They go through five nymphal stages (instars) requiring a blood meal to molt into each successive stage and to produce eggs as adults.

They do not knownly transmit diseases, but their bites can cause itchy red welts, allergic reactions, insomnia, and psychological distress. They provide no known ecological benefits to human environments.
