Abstract

An insecticide dispensing apparatus for delivering insecticide from an outside source to a building having a foundation and a roof space thereunder. The apparatus includes an access unit having an inlet port external to the building, an upper pipeline arrangement having at least one outlet is located in the roof space and extends to the access unit. A lower pipeline arrangement including at least one outlet is located under the foundation. This lower pipeline arrangement also extends to the access unit whereby insecticide is effectively distributed with respect to the building.

Claims

1. An insecticide dispensing apparatus for delivering insecticide from an outside source to a building having a foundation and a roof with a roof space thereunder, the apparatus comprising:

an access unit having an inlet port external to the building;

an upper pipeline arrangement in the roof space and extending to the access unit, the upper pipeline arrangement having at least one outlet in the roof space;

a lower pipeline arrangement under the foundation and extending to the access unit, the lower pipeline arrangement having at least one outlet under the foundation;

at least three connection points located at the access unit including a plurality of dry powder spray connectors and at least one liquid insecticide injector connector; and

an overflow indicator,

whereby insecticide is effectively distributed with respect to the building.

2. The insecticide dispensing apparatus of claim 1 wherein the foundation is a concrete slab.

3. The insecticide dispensing apparatus of claim 1 wherein the outlet in the upper pipeline arrangement is a spray head.

4. The insecticide dispensing apparatus of claim 3 wherein:

a plurality of spray heads are joined together with the upper pipeline arrangement and fixed to support beams located within the roof space in order to evenly disperse powdered insecticide over a controlled distance; and

the upper pipeline arrangement extends from the roof space through a cavity inside the house to the access unit, thereby allowing insecticide spray to be injected from outside the house through a powder injector connector to the system.

5. The insecticide dispensing apparatus of claim 4 wherein the spray heads include three-way spray heads.

6. The insecticide dispensing apparatus of claim 5 wherein the three-way spray heads include a deflection plate and a flow control.

7. The insecticide dispensing apparatus of claim 1 wherein:

the lower pipeline arrangement is built into a blue metal pebble soaker bed;

the lower pipeline arrangement is joined together with anchor-spray heads;

the blue metal pebble soaker bed is positioned under a concrete slab and around the perimeter of a house; and

the soaker bed and spray heads are wrapped in a protective netting and soil-proof casing, thereby preventing any foreign material from contaminating the soaker bed and spray heads.

8. The insecticide dispensing apparatus of claim 7 wherein:

the lower pipeline arrangement includes a plurality of holes; and

insecticide is dispersed from the holes in the lower pipeline arrangement as well as from the spray heads when a low pressurized liquid insecticide is injected into the system.

9. The insecticide dispensing apparatus of claim 1 wherein insecticides are injected via the liquid connector into the soaker bed to the overflow indicator located at the end of the lower pipeline arrangement.

10. The insecticide dispensing apparatus of claim 1 wherein only one liquid injector connector is located in the unit.

11. An insecticide dispensing apparatus for delivering insecticide from an outside source to a building having a roof with a roof space thereunder, the apparatus comprising:

an access unit having an inlet port external to the building;

a pipeline arrangement in the roof space and extending to the access unit, the pipeline arrangement having at least one outlet in the roof space;

at least three connection points located at the access unit including a plurality of dry powder spray connectors and at least one liquid insecticide injector connector; and

an overflow indicator,

whereby insecticide is effectively distributed within the roof space of the building.

12. The insecticide dispensing apparatus of claim 11 wherein the outlet in the pipeline arrangement is a spray head.

13. The insecticide dispensing apparatus of claim 12 wherein:

a plurality of spray heads are joined together with the pipeline arrangement and fixed to support beams located within the roof space in order to evenly disperse powdered insecticide over a controlled distance; and

the pipeline arrangement extends from the roof space through a cavity inside the house to the access unit, thereby allowing insecticide spray to be injected from outside the house through a powder injector connector to the system.

14. The insecticide dispensing apparatus of claim 13 wherein the spray heads include three-way spray heads.

15. The insecticide dispensing apparatus of claim 14 wherein the three-way spray heads include a deflection plate and a flow control.

16. An insecticide dispensing apparatus for delivering insecticide from an outside source to a building having a foundation, the apparatus comprising:

an access unit having an inlet port external to the building;

a blue metal pebble soaker bed positioned under a concrete slab and around the perimeter of the building;

a lower pipeline arrangement built into the blue metal pebble soaker bed under the foundation and extending to the access unit, the pipeline arrangement being joined together with anchor-spray heads and having at least one outlet under the foundation; and

a protective netting and soil proof casing wrapping the soaker bed and spray heads thereby preventing any foreign material from contaminating the soaker bed and spray heads.

17. The insecticide dispensing apparatus of claim 16 wherein the foundation is a concrete slab.

18. The insecticide dispensing apparatus of claim 16 wherein:

the lower pipeline arrangement includes a plurality of holes; and

insecticide is dispersed from the holes in the lower pipeline arrangement as well as from the spray heads when a pressurized liquid insecticide is injected into the system.

19. The insecticide dispensing apparatus of claim 18 wherein insecticides are injected via a liquid connector into the soaker bed to an overflow indicator located at the end of the lower pipeline arrangement.

20. The insecticide dispensing apparatus of claim 16 wherein only one liquid injector connector is located in the unit.
