Bait materials, pest monitoring devices and other pest control devices that include polyurethane foam
First Claim
1. A method for making a moisture-resistant composite bait material, comprising:
- providing a plurality of pieces of a cellulosic food material that is palatable to at least one species of termites in a bait enclosure, wherein the bait enclosure and the plurality of cellulosic food material pieces define a void space therebetween and the bait enclosure comprises a bait container including a body extending between a first end and a second end, an internal chamber, a first opening extending through the first end, and a second opening spaced apart from the first opening;
introducing an uncured mixture of polyurethane foam precursors into said bait enclosure such that said mixture enters at least some of the void space; and
allowing said mixture to cure to provide polyurethane foam matrix surrounding at least one of the plurality of said cellulosic food material pieces.

Abstract
A termite bait includes a plurality of cellulosic food material pieces palatable to termites embedded within a water resistant polyurethane foam matrix. Another termite bait includes a plurality of cellulosic food material pieces embedded within a water-absorbent polyurethane foam matrix. Yet another termite bait includes at least one cellulosic food material piece encapsulated within a water resistant polyurethane foam coating. Such termite baits can be used alone or in a monitoring device or other termite control device. Another termite control device includes a container, a cellulosic food material within the container and a water resistant polyurethane foam positioned to separate the food material from its environment. The container can contain a termite bait as described above or can include a chamber containing a cellulosic food material and at least one pocket containing a polyurethane foam barrier to reduce intrusion of water through the pocket to the food material.
