I'm concerned with using heat. How hot will my treatment area get?

There are many ways to kill bedbugs but heat is the most effective way to kill bedbugs. To give some perspective on how hot the treatment area will get, here is an example: On a sunny day of 70 degrees outside, a parked car in the sun with the windows rolled up will reach temperatures of 104-113 degrees in a couple of hours. If the temperature increase to 80 degrees outside under the same circumstances, the temperatures in the car will range from 130-172 degrees. Our temperature recommendations to treat range from 120-140 degrees.
