Freeze acts as a caloric shock that penetrates beyond the surface, target these hide egg to ascertain the full life cycle is stop before it commence again.
The Science Behind Cold Exposure
Heat course destroys protein structures, but frigidity doesn't needfully defeat instantaneously; it's more about inactivation. To does freezing kill weevil efficaciously, you have to consider the metabolous pace of the insects. Erstwhile the nucleus temperature of the nutrient drops importantly, the bugs enter a province of suspended animation. However, just chilling your flour in the fridge for an hour won't do the job.
