Certain items cannot be safely treated with insecticide, including cloths, and thus heat is prescribed. In one study, 30 minutes in the “hot” cycle of a dryer killed all life stages, while prolonged washing in 140°F water killed all life stages. Almost nothing died if soaked for two hours, and while all adults and nymphs died when soaked for 24 hours, yet all eggs survived.

A study on freezing bed bugs showed that 2 hours at 14°F killed all bed bugs and eggs when placed directly (not in clothes) in the freezer. But when a bag of laundry was placed in the freezer, it took about 8 hours for the temperature at the center of the bag to reach -17°C.<ref>[http://www.ingentaconnect.com/content/esa/jee/2010/00000103/00000001/art00018 Naylor, R.
