Composite material including a thermoplastic polymer, a pest food material and a pesticide
First Claim
1. A pest control device, comprising:
- a bait operable to be consumed or displaced by one or more species of pest; and
a housing at least partially enclosing said bait;
wherein said bait includes a composite material including a plastic structural matrix;
a cellulosic food material contained within the matrix that is palatable to the pest; and
a pesticide contained within the matrix that is toxic to the pest.

Abstract
Composite materials that are palatable to a wood-destroying pest species and also pesticidal to the pest species can be used in pest control devices and can be used as wood substitutes for structural components, which are resistant to destruction by wood-destroying pests. The composite materials include a thermoplastic polymer, a food material for the pest and a pesticide. The composite material is formed by mixing a thermoplastic polymer, wood fragments or other cellulosic materials and a quantity of pesticide, and thereafter creating a molten material within a mixer, compounder, extruder or the like. The molten material is extruded or molded to form the desired shape.

12. A pest control system comprising at least two pest control devices each arranged to be spaced apart from one another in an area to be protected from one or more pests, at least one of said pest control devices including a bait that is operable to be consumed or displaced by the pest and that includes a composite material including a plastic structural matrix;
- a cellulosic food material contained within the matrix that is palatable to the pest; and
a pesticide contained within the matrix that is toxic to the pest.

13. A method, comprising:
-
providing a pest control device including a pesticidal bait for one or more species of pest; and installing the device in an area to be protected from the pests; wherein the pesticidal bait includes a composite material including a plastic structural matrix;
a cellulosic food material contained within the matrix that is palatable to the pest; and
a pesticide contained within the matrix that is toxic to the pest. - View Dependent Claims (14, 15)

16. A method for making a composite material, comprising:
-
providing a mixture of a softened or molten thermoplastic polymer having a softening or melting point below about 220°
C., a cellulosic food material that is palatable to at least one species of wood-destroying pest and a pesticide that is toxic to the pest;forming the mixture to provide a workpiece having a desired shape; and cooling the workpiece to a temperature below the softening or melting point of the plastic to provide a solid composite article; wherein the composite material exhibits greater palatability than untreated wood in a standard one-way paired-choice test. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A composite material comprising:
-
a plastic structural matrix; a cellulosic food material contained within the matrix that is palatable to at least one species of wood-destroying pest; and a pesticide contained within the matrix that is toxic to the pest; wherein the composite material is operable to be consumed or displaced by the pest; wherein the composite material exhibits greater palatability than untreated wood in a standard one-way paired-choice test; and wherein the plastic structural matrix comprises a thermoplastic polymer having a melting point below about 220°
