PLAN No. 537. INSECT POWDER
Girl No. 5 was rooming at a house where cockroaches were driving the landlady almost frantic, and gladly chose the following formula as her field of operations: Persian insect powder, 4 ounces; borax 30 ounces; starch, 4 ounces; sugar, 3 ounces; cocoa, 4 ounces; tartar emetic, 4 ounces. Reduce all to a fine powder and mix thoroughly.
The landlady was her first customer, and soon dispelled the roaches. Then the girl visited all the rooming houses, hotels, bakeries, cafes, etc., in the city, and made good sales. The drug stores sold considerable of it also, while women canvassers sold some, and the profits of her plan in the six months were $275.
