Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective. An hour at a temperature of 45 Â°C (113 Â°F) or over, or two hours at less than â17 Â°C (1 Â°F) kills them. This may include a domestic clothes drier for fabric or a commercial steamer. Bed bugs and their eggs will die on contact when exposed to surface temperatures above 180 Â°F (82 Â°C) and a steamer can reach well above 230 Â°F (110 Â°C). A study found 100% mortality rates for bed bugs exposed to temperatures greater than 50 Â°C (122 Â°F) for more than 2 minutes. The study recommended maintaining temperatures of above 48 Â°C (118 Â°F) for more than 20 min to effectively kill all life stages of bed bugs, and because in practice treatment times of 6 to 8 hours are used to account for cracks and indoor clutter. This method is expensive and has caused fires. Starving bedbugs is not effective, as they can survive without eating for 100 to 300 days, depending on temperature.
