Bed bugs can survive a wide range of temperatures. But a combination of heat and drying has proven effective at killing them. Studies have shown that all stages of life are killed by seven minutes of exposure to a heat of 115 °F. Other studies have found that bed bug eggs were only be destroyed after 90 minutes of exposure to 118 °F. Running affected clothes through a regular dryer on high heat for an hour can sometimes work to kill the bugs.
