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.

Claims

1. A pest control device, comprising:

a bait adapted to be consumed or displaced by at least one species of termites; and

a housing at least partially enclosing said bait;

wherein said bait includes an extruded composite material that is palatable to termites; and

wherein said composite material includes from about 5% to about 50% by weight of a plastic structural matrix comprising cellulose acetate butyrate;

from about 50% to about 85% by weight of alpha cellulose contained within the matrix; and

from about 0.001% to about 5% by weight of noviflumuron contained within the matrix.
