Method of Applying Powder to Kill Insects

Abstract

A method of improving the performance of a powder dusting tip delivering powdered diatomaceous earth powder minimizing clogging in powder bulb duster tips through the use of tips with a more free flowing configuration and different spray patterns than the standard tip assembly and a flexible one piece powder dusting tube, which is attached to the tips which connects to reservoir of powder type insect repellents such as diatomaceous earth pesticides, boric acid pesticides, sevin based insecticides, deltamethrin based insecticides, and permethrin based insecticides as well as other powdered insecticides through threaded connections, made from flexible rubber tubing supported by memory wire that allows the powder duster tip to be positioned for hard to reach areas.

Claims

1. A method for spraying insecticide powder, such as such as diatomaceous earth pesticides, boric acid pesticides, sevin based insecticides, deltamethrin based insecticides, and permethrin based insecticides as well as other powdered insecticides comprising: a first step of preparing a plurality of different kinds of tips that all have wide openings to direct a spray over a large area; a second step of molding the tips in a one piece configuration with a flexible rubber tube(ing), with an internal flex wire being attached to the flexible rubber tube(ing); a third step of molding a threaded female end, on the end of the flexible rubber tube(ing) away from the tip, in the one piece configuration; a fourth step of attaching the threaded female end to a male threaded end that resides in the base of a reservoir and/or spraying apparatus containing the insecticide powder being spread; the plurality of tips comprising; a tapered stream tip a non-tapered stream tip; a fan tip; a cloud tip.

2. The method of claim 1 where the only tip is a tapered stream tip.

3. The method of claim 1 where the only tip is a non-tapered stream tip.

4. The method of claim 1 where the only tip is a fan tip.

5. The method of claim 1 where the only tip is a cloud tip.

6. The method of claim 1 where only two of the four tips are used.

7. The method of claim 1 where only three of the four tips are used.

DETAILED DESCRIPTION

[0038] FIG. 1 shows the tapered stream tip 2, with the top section 1 being a part of the one piece molded tip 2 and flexible rubber tube 13, with an internal flex wire 12 that is attached to the tip is a section, 3, with the end of the flexible rubber tube 13, away from the tip, having a female thread 4 that attaches to the container source and/or spraying apparatus with the insecticide powder being sprayed.

[0039] FIG. 2 shows the cloud tip 7, which has a center support 6, and that attaches to the tip 7 through cross section pieces 5. The cloud tip 7, being the top section 1 being a part of the one piece molded cloud tip 7 and flexible rubber tube 13, with an internal flex wire 12 that is attached to the tip with a section, 3, with the end of the flexible rubber tube 13, away from the tip, having a female thread 4 that attaches to the container source and or spraying apparatus of the insecticide powder being sprayed.

[0040] FIG. 3 shows the cloud tip 7 from the top, showing the pillar in the middle 6 and the cross section pieces 5

[0041] FIG. 4 shows how the flexible rubber tube connects to a base within the reservoir container 8 and/or spraying apparatus which has a male thread 14 that connects to the female thread of the flexible rubber connecting tube 13 with the flexible rubber tube's internal flex wire 12.

[0042] FIG. 5 shows a non-tapered stream tip 15 with the top section 15 being a part of the one piece molded tip 2 and flexible tube 13, with an internal flex wire 12 that is attached to the tip is a section, 3, with the end of the flexible tube 12, away from the tip, having a female thread 4 that attaches to the container source and/or spraying apparatus of the insecticide powder being sprayed.
