Individual items, for example, can be wrapped in plastic and placed in a hot, sunny location for at least a few days (the 120°F minimum target temperature should be monitored in the centermost location with a thermometer). Bedbugs also succumb to cold temperatures below freezing, but the chilling period must be maintained for at least two weeks.? 热水浸泡、阳光曝晒;Point steam on them.?You may get a simple device capable of generating steam at your local hardware store. You may also convert a simple electric kettle to a steam machine by attaching a flexible tube. Steam should kill all bedbugs and the eggs. Thoroughly spray steam at all corners and seams. 喷蒸汽;Vacuum your house.?This will remove bugs and eggs from mattresses, carpet, walls and other surfaces. Pay particular attention to seams, tufts and edges of mattresses and box springs, and the perimeter edge of wall-to-wall carpets. Afterward, dispose of the vacuum contents in a sealed trash bag. Steam cleaning of carpets is also helpful for killing bugs and eggs that vacuuming may have missed. 真空吸尘器; Steaming and spot-freezing equipment also have limited ability to penetrate fabric, wood, and other materials where bed bugs often reside.? 蒸汽（左）、冷冻（右）杀灭效果有限; Discard affected items.?In some cases, infested mattresses and box springs will need to be discarded. Since bed bugs can disperse throughout a building, it also may be necessary to inspect adjoining
