A bag for protecting grains from insect pests harmful to stored grains is produced by treating one piece of kraft paper with an insecticidal solution containing a pyrethroide insecticide, laminating 1 to 5 pieces of kraft paper, to which the pyrethroidal insecticidal compound is not applied, onto the insecticidally unprocessed surface of the former kraft paper, and then forming the resulting kraft paper laminate into a bag so that the surface, to which the pyrethroid insecticide has been applied, of the former kraft paper faces the outside. When grains are preserved in the bag according to the present invention, the grains can effectively be protected from insect pests harmful to stored grains.
