  • Patent number: 5063706
    Abstract: A device for exterminating pests having a cylinder filled with carbon dioxide in which (a) pesticide(s) is(are) dissolved, piping coupled to the cylinder, and a plurality of capillary nozzles affixed to the piping, and a method of exterminating pests employed this device. The capillary nozzles are designed such that, considering adjacent capillary nozzles, the ratio of the nozzle exit area of the capillary nozzle close to the cylinder to the nozzle exit area of the capillary nozzle remote from the cylinder is set between 1:1.3 and 1:1.8. As a result, numerous independent enclosed spaces can be sprayed with little labor and in a short time by means of a small number of devices.

  • Patent number: 4966796
    Abstract: 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.
