Abstract: A method for the extermination of burrowing vermin is disclosed. The method employs a smoke generating fluid formed of castor oil or castor oil in a mix with secondary components. The fluid is heated to a smoking temperature and the smoke is mixed with a pressurized airflow to communicate the smoke to the tunnels occupied by the burrowing vermin to remove them, and to leave a residue from the smoke which exudes an order deterring the re-occupancy of the tunnels.

Abstract: Improved air directing assemblies are provided. More particularly, the present disclosure provides improved air directing assemblies for use with beekeeping smoker assemblies or the like. The present disclosure provides for an air directing assembly that provides or blows a constant, continuous and/or directed stream of air into and/or to a smoker assembly, thereby providing a sufficient/adequate and/or improved amount of smoke to the bees, which thereby keeps the bees calm when the hive is open by the user. The air directing assemblies of the present disclosure prevent the fire in a smoker assembly from going out, and they can replace the pumps/bellows typically associated with smoker assemblies. These improved air directing assemblies can be modified to mount with respect to and/or be utilized with a wide variety of smoker assemblies or the like.

Abstract: A method of pest control for burrowing animals involves loading a machine-conveyed dispensing apparatus with a fumigant product, and using the machine to make one or more passes across an area of ground beneath which the burrow system is situated. A ground engagement tool of the dispensing apparatus is engaged in the ground to pass through or nearby sections of the burrow system, and fumigant product is dispensed into the ground behind a leading portion of the ground engagement tool. Fumigant is widely spread over the burrowed area of ground for effective results, while the human exposure and manual effort associated with conventional hand-placed fumigant techniques is greatly reduced.

Abstract: A smoke generating device is disclosed which utilizes a rechargable cartridge containing a vaporizable, smoke producing solution. The cartridge includes an aperture which is filled by a one-way, flap-type seal. When mounting the cartridge to the smoke generating device, a feed tube is inserted through the flap-type seal into the cartridge. In this manner, the contents of the cartridge are supplied to a valve means within the smoke generating device. When the valve means is actuated, the smoke producing fluid flows through a vaporizer coil. Heat supplied by a gas burner or other heating device vaporizes the smoke producing solution which issues as a dense simulated smoke from a smoke discharge nozzle. In a preferred embodiment of the invention, a flow restricting means is provided in the vaporizer coil to maintain the rate of flow of smoke producing liquid within a predetermined range.

The center area is fixedly attached to the one end of the inner portion and to the outer portion. The device is fabricated by folding the inner portions upward into a parallel position to provide a space therebetween for holding a combustible package.

Abstract: Readily portable apparatus for exterminating animal pests, particularly rodents such as gophers which burrow through the ground. The apparatus includes a small, lightweight internal combustion engine, and means for directing the engine exhaust into exterminating relationship to the pests, such as into a burrow or tunnel of a ground burrowing rodent. The preferred engine is a two-cycle engine which burns a fuel/oil mixture to produce exhaust containing smoke which asphyxiates, carbon monoxide which effectively poisons, and intense pressure pulsations which tend to drive a rodent from an underground tunnel, such that the rodent faces the delema of remaining underground and dying from the effects of the exhaust gas or coming to the surface and exposing himself to death in other ways above ground. In the presently preferred apparatus, the engine is mounted on an inverted bowl-shaped exhaust shroud which seats on the ground to direct the engine exhaust into an underground rodent burrow.
