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.
Claims7
A method for generating and communicating a noxious airstream to underground tunnels of burrowing vermin, comprising:
- placing a smoke generating fluid supply formed of at least castor oil into a reservoir;
- mixing said smoke generating fluid supply to contain the castor oil at an amount between 40 to 100 percent of a total volume of the smoke generating fluid supply and mineral oil between 10 to 60 percent of the total volume of the smoke generating fluid supply;
- communicating heat to the fluid supply to heat said fluid supply to a temperature at or above a smoking temperature, but below a combusting temperature for said fluid supply to generate smoke;
- communicating a pressurized airstream through said reservoir to an exit at an exhaust port in communication with said reservoir;
- communicating said pressurized airstream and said smoke carried thereby exiting said exit to said underground tunnels;
- and
- continuing communicating said pressurized airstream and said smoke to said underground tunnels to allow said smoke to impart residue therefrom to surfaces of said underground tunnels, whereby said burrowing vermin are removed from occupancy of said tunnels and said residue communicates a residual scent from said smoke to said tunnels as a long term deterrent from re-occupancy thereof.
