  • Termite bait matrix
    Patent number: 6585991
    Abstract: Termite foods mixed together in a matrix suitable to be used as baits and attractants for termites are provided. This termite matrix is preferred by termites over naturally-occurring foods such as deadwood, trees and wood used in human constructions, and other known termite matrices. It comprises cellulose, water and termite-preferred nutrients. Methods of monitoring the presence of termites using such matrices, and methods of controlling termites using such matrices to deliver termite toxins are also provided.
