Bed bugs are becoming more common as people are travelling more these days. They are easily transported from one place to the next. For example, backpackers and hotels etc. They are visible to the naked eye and are mainly found in mattresses, bed frames and carpet. They bite humans while sleeping leaving red, itchy welts. Treatment for bed bugs involve washing all bedding in hot, soapy water; removing contents of room; and spraying all bedding and furnishings.
