Bed bugs are small, nocturnal insects that feed on human blood, causing itchy bites and emotional distress.
They are attracted by body heat, CO2 from breath, natural body odour, and stillness of hosts during sleep.
Common hiding spots include mattresses, furniture seams, and personal belongings, with signs like bites and stains.
Prevention includes inspecting used items, reducing clutter, and using heat treatments or essential oils.
