Iowa and other mid-western states suffered tremendous grasshopper losses in 1936. Although the heaviest damage occurred in the western and southern counties, the infestation extended across the southern half of the state and up along the Mississippi River into a number of northeastern counties. In fact, more or less damage occurred in all save about 25 counties located in the northcentral part of the state. Over 21,000 farmers broadcast 200 or more pounds of poison bait on their respective farms, and a total of 4,463 tons of dry bait materials were wet and mixed at 52 county mixing stations.
