Every year, in the United States and Canada, Thoudands of dollars worth of stored grain is ruined by granary insects, chiefly of three species. These are all well known, and much has been written concerning their habits and the methods by which they can be destroyed. Besides the three very injurious species, the Granary Weevil, the Rice Weevil and the Angoumois Grain Moth, which are responsible for the most of the damage done, there are a great many other kinds of insects which do serious harm to stored grain and various other edible products.
