Steam is an effective way to kill bed bugs and their eggs, thanks to the high temperatures proving lethal. If you’re worried about an infestation, then steam cleaning soft furnishings can help. Make sure that you use the upholstery attachment and/or mattress accessory to clean. You should move slowly over the area, taking at least 30 seconds before moving the steam head in order to deliver a killing dose of steam. Make sure that you cover all areas, and press the steam head into crevices and around the bed; for mattresses, cover the sides and underneath, too.
