It might just be an efficient way of killing them that everyone can use. According to 'Insects Are Food': http://www.insectsarefood.com/recipes.html http://www.insectsarefood.com/recipes.html "Prior to preparing your crickets for a meal place them inside a plastic container or storage bag and keep them in the refrigerator at least for an hour or until you are ready to use them. This will not kill the crickets, but rather slow down their metabolism, inducing a state of hypothermia, in other words, prohibiting their movement when removed from container. If you prefer however, as many people do, feel free to place them inside the freezer for an hour or two as this will definitely kill them, guaranteeing their immobility. After removing from refrigerator or freezer, place them in a pot of boiling water sized to hold the specific amount of crickets you’re using. Add a few pinches of salt. Boil for about two minutes. This ensures cleanliness. Once boiled, remove from water and let cool. Crickets at this time can be placed in storage bags and kept in the freezer or used right away for any number of recipes. All crickets should be prepared in this manner prior to eating." There also appears to be discussion of what the most human way to kill farmed insects is: http://en.wikipedia.org/wiki/Welfare_of_farmed_insects http://en.wikipedia.org/wiki/Welfare_of_farmed_insects
