Termite tubing preventative for non-wood materials
The present invention relates to materials and methods for protecting man-made structures made with non-wood materials from termite damage through the application of borates to the surface of non-wood materials. In an embodiment the invention regards a method for preventing termite tunneling and tubing on non-wood and/or non-cellulosic materials by treating non-wood building components comprising the steps of applying a composition to the surfaces of a non-wood building component, wherein the composition comprises a borate component. In another embodiment the invention regards a method for preventing termite damage to man-made structures comprising the steps of mixing borates with a solvent to form a borate solution, obtaining a non-wood building component, coating the non-wood building component with the borate solution, and incorporating the coated non-wood building component into a man-made structure. The invention also regards a non-wood building component comprising a non-wood substrate, and a coating comprising borates, wherein the coating is disposed on the surfaces of the non-wood substrate.
