Smaller items that cannot be laundered can sometimes be de-infested by heating. 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. Attempts to rid an entire home or apartment of bed bugs by raising or lowering the thermostat will be entirely unsuccessful.
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.
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.
Repair cracks in plaster and glue down loosened wallpaper to eliminate bed bug harborage sites: Remove and destroy wild animal roosts and bird nests when possible.
Consider using insecticides. Residual insecticides (usually pyrethroids) are applied as spot treatments to cracks and crevices where bed bugs are hiding. Increased penetration of the insecticide into cracks and crevices can be achieved if accumulated dirt and debris are first removed using a vacuum cleaner. Many readily available aerosol pesticide sprays will cause bed bugs to scatter making eradication more difficult. Dust formulations may be used to treat wall voids and attics.Repeat insecticide applications if bed bugs are present two weeks after the initial treatment. It is difficult to find all hiding places and hidden eggs may have hatched.
Enlist the services of a professional pest control firm: Experienced companies know where to look for bed bugs, and have an assortment of management tools at their disposal. Owners and occupants will need to assist the professional in important ways. Allowing access for inspection and treatment is essential and excess clutter should be removed.
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 rooms and apartments.
