Below is the Fahrenheit conversion of the white paper chart for beetle mortality that I redid when I discovered beetles in my party short cab.

Keep in mind that most home freezers at their lowest setting only go down to about 17 degrees F. As long as the larval stage has not been acclimated to 60 degrees for several months before freezing occurs, 4 days in a home freezer should result in 100% mortality.
