Great writeup SilverFox. Thanks. I think I might start freezing my sticks.

In case this one gets stickied, here is the Fahrenheit conversion of the white paper on cigarette beetle mortality I posted in another thread on this topic.

--------
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.
