Abstract

A system for exterminating insects and several embodiments thereof are presented. Steam is generated and transported to a movable applicator. The applicator is positioned over a designated area of ground and the steam is applied exterminating the insects on and/or under the designated area of ground.

Claims (40)

1. An extermination system for exterminating insects on a designated area of ground and under the designated area of ground utilizing an insect tunnel network and without using a probe, the system comprising:

a boiler with liquid;

a power source for heating the liquid and converting it to steam in the boiler;

a steam transport system for delivering steam from the boiler to an applicator;

an applicator for placement on to and over the designated area of ground such that steam from the boiler is applied on to the designated area and into insect tunnel networks without forcing a probe into the ground;

wherein the steam transport system and the applicator are configured so that the pressure and temperature of the steam is maintained low enough such that, when the applicator is placed on the designated area of ground, the steam will not damage or collapse the insect tunnel networks; and

wherein, when the applicator is placed on the designated area of ground, insects on the designated area of ground under the applicator are exterminated directly by the steam and insects underground are exterminated, without the use of a probe, by the steam entering into the tunnel network at the ground surface on the designated area of ground and traveling underground through the tunnel network.

2. The system as set forth in claim 1 wherein the liquid in the boiler is water.

3. The system as set forth in claim 1 further comprising a mechanism for raising and lowering the applicator on and off the designated area of ground.

4. The system as set forth in claim 3 wherein the mechanism for raising and lowering the applicator is thermally isolated from the exterminator such that an operator will not be burned.

5. The system of claim 3 further wherein the mechanism for raising and lowering the applicator on to the designated area of ground is manually operated.

6. The system as set forth in claim 3 wherein the mechanism for manually lowering and raising may be used for transporting the system.

7. The system as set forth in claim 3 further comprising:

power means for automated raising and lowering of the applicator.

8. The system as set forth in claim 1 wherein the system is configured such that a seal is created between the bottom perimeter of the applicator and the ground when the applicator is lowered preventing or minimizing steam from escaping directly into the air.

9. The system as set forth in claim 1 further comprising:

a sensor for sensing the amount of liquid in the boiler.

10. The system as set forth in claim 9 further comprising;

a shut-off device coupled to the sensor for shutting off the power source when the liquid level has dropped to pre-determined level.

11. The system as set forth in claim 1 wherein the power source further comprises:

a burner for heating the liquid and converting the liquid into steam; and

a fuel source coupled to the burner for delivering fuel to the burner.

12. The system as set forth in claim 11 further comprising:

an igniter for igniting the fuel at the burner.

13. The system as set forth in claim 12 wherein the fuel is a gas.

14. The system as set forth in claim 1 wherein the power source comprises:

one or more electrically powered electrodes immersed in the boiler for converting the water into steam.

15. The system as set forth in claim 1 further comprising:

system transport means for transporting the system to and from designated areas of ground.

16. The system as set forth in claim 1 further comprising:

a control panel for remotely operating and/or monitoring the system.

17. The system as set forth in claim 1 wherein no insecticidal fog is used.

18. A method of exterminating insects on a designated area of ground and under the designated area of ground utilizing an insect tunnel network and without using a probe with an extermination system, the extermination system having a boiler with liquid; a power source for heating the liquid and converting the liquid to steam; a steam transport system for delivering sufficient volume of steam from the boiler to an applicator; an applicator for placement on to and over the designated area of ground such that steam from the boiler is applied on to the designated area and into insect tunnel networks without forcing a probe into the ground; the method comprising the steps of:

generating steam;

moving the applicator on to the designated area of ground;

transporting the steam to the applicator;

maintaining the pressure and temperature of the steam at a low enough level so that the steam does not collapse or damage the insect tunnel network;

forcing the steam on to the ground and into the insect tunnel network at the ground surface on the designated area of ground, the steam permeating the insect tunnel network and exterminating the insects.

19. The method as set forth in claim 18 further comprising the step of:

transporting the extermination system to and/or from the designated area of ground.
