Abstract

A pest control and/or detection system generally includes an electrically conductive bait matrix including at least one carrier material that is at least one of palatable, a phagostimulant and/or consumable and/or displaceable by pests, and a plurality of electrically conductive particles. The electrically conductive particles are substantially randomly interspersed throughout the at least one carrier material. The at least one carrier material includes a thermoplastic material and/or a resin.

First claim

What is claimed is:

1. A bait matrix formulation, comprising:
a carbohydrate material;
a polymer;
a carbonaceous material selected from the group consisting of graphite, charcoal, coke, carbon nanotubes, coconut shells, or mixtures thereof; and
a foaming agent.

2. The bait matrix formulation of claim 1 , wherein the carbohydrate material is predominantly cellulose.

3. The bait matrix formulation of claim 1 , wherein the polymer comprises a thermoplastic polymer.

4. The bait matrix formulation of claim 1 , wherein the foaming agent comprises a material compatible with the polymer that will cause a cellular structure to be formed in at least a portion of a bait matrix.

5. The bait matrix formulation of claim 1 , wherein the formulation comprises approximately 40 to 60 percent by weight of the carbohydrate material.

6. The bait matrix formulation of claim 1 , wherein the formulation comprises approximately 30 to 50 percent by weight of the polymer.

7. The bait matrix formulation of claim 1 , wherein the formulation comprises approximately 5 to 10 percent by weight of the carbonaceous material.

8. The bait matrix formulation of claim 1 , wherein the formulation comprises approximately 1 to 4 percent by weight of the foaming agent.

9. The bait matrix formulation of claim 1 , wherein the formulation comprises approximately 55 percent by weight of the carbohydrate material, approximately 31 percent by weight of the polymer, approximately 10 percent by weight of the carbonaceous material, and approximately 4 percent by weight of the foaming agent.

10. A bait matrix formulation for enhanced palatability and sustained feeding and exploitation by termites, comprising:
approximately 40 to 60 percent by weight of a carbohydrate material;
approximately 30 to 50 percent by weight of a polymer;
approximately 5 to 10 percent by weight of a carbonaceous material selected from the group consisting of graphite, charcoal, coke, carbon nanotubes, coconut shells, or mixtures thereof; and
approximately 1 to 4 percent by weight of a foaming agent.

11. The bait matrix formulation of claim 10 , wherein the carbohydrate material is predominantly cellulose.

12. The bait matrix formulation of claim 10 , wherein the polymer comprises a thermoplastic polymer.

13. The bait matrix formulation of claim 10 , wherein the foaming agent comprises a material compatible with the polymer that will cause a cellular structure to be formed in at least a portion of a bait matrix.

14. A method for sustaining the feeding and exploitation of a bait matrix by termites, comprising:
formulating a bait matrix mixture comprising a carbohydrate material, a polymer, a carbonaceous material, and a foaming agent, wherein the carbonaceous material is selected from the group consisting of graphite, charcoal, coke, carbon nanotubes, coconut shells, or mixtures thereof;
having the bait matrix mixture formed into a rigid structure;
directing the placement of the bait matrix structure within an area where there is potential for termite presence.

15. The method of claim 14 , wherein the bait matrix mixture further comprises approximately 40 to 60 percent by weight of the carbohydrate material; approximately 30 to 50 percent by weight of the polymer; approximately 5 to 10 percent by weight of the carbonaceous material; and approximately 1 to 4 percent by weight of the foaming agent.

16. The method of claim 15 , wherein the carbohydrate material is predominantly cellulose.

17. The method of claim 15 , wherein the polymer is a polyester.
