Segment 2 The narrator explains that smaller farming communities with less access to modern farming methods are especially at risk from insect infestation. African women preparing maize are shown. They mix a protectant into the maize before storing it in a hut. Various other uses of Pybuthrin, an insecticide that is harmful to insects but not food or humans, are described. These include at the grain silos, docks, in bulk storage, to treat food preparation machinery, and in a grocers. Examples of food that became infested are shown.
