Termite tubing preventative for non-wood materials

#The present invention relates to materials and methods for protecting man-made structures from termite damage by treating non-wood and/or non-cellulosic materials. More particularly, the present invention relates to the application of borates to the surface of non-wood and/or non-cellulosic materials.

#Termites are unique among insects in their ability to derive nutritional benefit from cellulose, which is the component of wood and plants that gives structural rigidity to cells. However, as a result of feeding on wood and cellulose containing products, termites can cause significant damage to man-made structures and the cellulose materials contained within.

#Generally speaking, subterranean termites must stay in close reach of the soil at all times, lest they die from dehydration. Accordingly, wood touching soil is easily accessed and damaged by termites. However, subterranean termites also can build shelter tubing to travel between the soil and wood that is nearby, but not actually touching the soil. The shelter tubing provides a dark, moist environment that protects the termites from sunlight, predators, or dehydration. Termites may also build shelter tubes through the soil to avoid certain highly repellant termiticides.

#The invention may be more completely understood in connection with the following drawings, in which:

#FIG. 1 is a cross-section of a non-wood building component with a borate solution coating.

#FIG. 2 is an example of termite tubing behavior on a non-wood building component with a borate solution coating and on a non-wood building component without a borate solution coating.

#While the invention is susceptible to various modifications and alternative forms, specifics thereof have been shown by way of example and drawings, and will be described in detail. It should be understood, however, that the invention is not limited to the particular embodiments described. On the contrary, the intention is to cover modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

#Where a borate composition is applied to a non-wood substrate in accordance with the invention, termites attempt to form tubes, but there is very rapid termite mortality and therefore a discontinuation of tubing activity on the treated non-wood substrates.

#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.
