Cream shortening and sugar, mix boric acid, flour and onion. Add to sugar, and oil. Blend well, then add more oil as needed to form a soft dough. Shape into small balls the size of marbles. (If balls are placed in opened, plastic sandwich bags, the dough will stay softer longer.) Place balls throughout the house in places normally inhabited by roaches (any dark, damp corner). Caution- Make sure no children or pet can come in contact with these balls, as it is toxic and keep out of direct contact with any food. When dough becomes brick hard, replace with a fresh batch.
