Examine the following areas thoroughly: headboards, bed frames, mattresses, door and window frames, light fixtures, wall hangings, tables, chairs, sofas, and curtains.
Bed bugs often leave noticeable, itchy, red bite marks on the skin, commonly found on the neck and arms.
Another telltale sign is their excrement, which appears as small dark spots on sheets, mattresses, bed frames, pillows, blankets, and other frequently used surfaces. Additionally, they may leave behind small bloodstains in these areas.
The presence of dead bugs is another clear indication of an infestation. Once bed bugs have infiltrated the building's structures, only pest control experts can effectively eradicate them.
