Bed bugs can be killed by exposing them to extreme temperatures, either high heat or freezing cold. The temperature and exposure time required to kill bed bugs depend on the method used. Here are the temperatures that kill bed bugs according to the search results:

• 113°F for 90+ minutes: Bed bugs exposed to this temperature for at least 90 minutes will die.
• 118°F for 20 minutes: Bed bugs will die within 20 minutes if exposed to this temperature.
• 118°F for 90 minutes: Bed bug eggs must be exposed to this temperature for 90 minutes to reach 100% mortality.
• 131°F for a few hours: This temperature is effective in killing bed bugs.
• 140°F for a few hours: This temperature kills all stages of bed bugs after a few hours.
• 0°F for at least 3 days: Freezing infested items at this temperature will kill bed bugs.

Its important to note that extreme temperatures beyond what can be achieved naturally are required to get rid of bed bugs. Homeowners can use extreme temperature to kill bed bugs in a limited sense, but DIY heat or cold treatments arent a practical solution for house-wide infestations. In addition to letting bed bugs in floorboard cracks and walls escape, this control method wont work for infested items that cant be heated or frozen. Its best to hire a professional bug removal service to eradicate the infestation.
