According to the search results, heat is known to be a very effective bed bug killer and can be used in many different ways to treat infestations. The temperature at which bed bugs die depends on the exposure time and the life stage of the bed bug. Adult bed bugs die at 113°F if they receive constant exposure to that temperature for 15 minutes or more, or in just 20 minutes if exposed to a heat of 118°F. Bed bug eggs are the most robust life stage and must be exposed to a temperature of 113°F for a full 60 minutes to ensure 100% mortality. The temperature required to kill bed bugs is beyond what can be achieved naturally, so special equipment and expert monitoring are required. Whole-room heat treatments are based on a thermal death point of 113°F, and these treatments have been very successful due to the use of powerful fans to create convection currents within the heated room. Once the bed bug thermal death point is reached at all sensors, the heating process is continued for 60 minutes or more to kill all of the bed bugs and their eggs. Therefore, it can be concluded that bed bugs can be killed by exposing them to a temperature of at least 113°F for a certain period of time, depending on the life stage of the bed bug.
