Bed bugs can be killed using high heat or very cold temperatures. Research has shown that bed bugs die when exposed to temperatures of 113°F for at least 90 minutes or 118°F for 20 minutes. 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 be sure of 100% mortality. To kill bed bug eggs, expose the sacs to 118°F for 90 minutes. Its worth noting that whole room heat treatments have been very successful, even though they are based on a thermal death point of 113°F. The use of powerful fans to create convection currents within the heated room heats the bed bugs very rapidly, thus increasing their mortality.

In summary, bed bugs can be killed by exposing them to temperatures of at least 113°F for a certain amount of time, depending on the life stage. Bed bug eggs are the most difficult to kill and require a temperature of 113°F for a full 60 minutes. Whole room heat treatments have been successful due to the use of powerful fans to create convection currents within the heated room.
