Abstract

A system and method for treating items suspected of insect infestation is described. The items are placed in a treatment space inside a treatment container together with a composition comprising one or more volatile components with insecticidal activity. The composition is applied to an absorbent material capable of containing the composition in a treatment amount; and the absorbent material and the composition are enclosed in a diffuser container with perforations covering about 1 to 30% of a surface area of the walls that allow diffusion of the one or more volatile components into the treatment space.

First claim

What is claimed is:

1. A method for treating an item suspected of insect infestation comprising
enclosing the item and a diffuser container inside a treatment container for a treatment time, the diffuser container comprising:
(i) an absorbent material,
(ii) 40 to 100 mL of a composition absorbed onto the absorbent material, the composition comprising 2 to 10 wt. % neem oil; and
(iii) perforations; wherein the diffuser container is constructed to allow diffusion of the neem oil through the perforations during the treatment time at a rate of 0.5 to 10 grams per hour.

2. The method of claim 1 , wherein the treatment container defines a treatment space inside the treatment container, wherein the neem oil is present at a treatment concentration in the treatment space for at least a majority of the treatment time, and wherein the treatment concentration has an insecticidal effect on a target insect.

3. The method of claim 1 , wherein the treatment time is between 3 to 21 days.

4. The method of claim 1 , wherein the treatment time is 24 to 48 hours.

5. The method of claim 1 , wherein the absorbent material is selected from the group consisting of cloth, rag, cotton, wool and cellulosic fibers.

6. The method of claim 1 , wherein the absorbent material is configured as a pad.

7. The method of claim 1 , wherein the diffuser container volume is 250 mL to 500 mL.

8. The method of claim 1 , wherein the diffuser container volume is 20 to 150 mL.

9. The method of claim 1 , wherein the diffuser container is a material selected from the group consisting of plastic, metal, fiber, fabric, paper, and combinations thereof.

10. The method of claim 1 , wherein the perforations on the diffuser container are located on one side of the diffuser container.

11. The method of claim 1 , wherein the perforations on the diffuser container are located on more than one side of the diffuser container.

12. The method of claim 1 , the diffuser container further comprising a removable seal covering the perforations.
