In order to disinfest materials from all stages of insects, a freezer which can maintain and hold at least -20°F is mandatory. A chest freezer doesn’t lose much cold when you open the door to load it vs. an upright one. The object is to lower the materials to minus 32°F within four hours after putting the materials in the freezer. This scenario beats the insects from being able to build up their natural antifreeze.
