This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,950.

Background and Problem Solved

The original patent disclosed a termite resistant wood preservative composition comprising cold pressed orange oil and acrylic lacquer. However, the composition's stability and shelf life were limited, and its insecticidal properties could be further enhanced. This invention addresses these limitations by introducing an antioxidant additive to stabilize the cold pressed orange oil, incorporating permethrin for enhanced insecticidal properties, and developing new methods and systems for its application and use.

Novelty and Inventive Step

The new invention's novelty lies in the introduction of an antioxidant additive to stabilize the cold pressed orange oil, the incorporation of permethrin for enhanced insecticidal properties, and the development of new methods and systems for its application and use. The inventive step is the recognition that the original composition's limitations could be addressed by these enhancements, providing a more effective and efficient termite repellent and wood protector.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include varying the concentration of the antioxidant additive, using different types of insecticides, or incorporating additional components to enhance the composition's properties. Variations of the method for applying the composition may involve different application techniques, such as brushing or rolling, or using different types of spray apparatus.

Potential Commercial Applications and Market

The enhanced termite repellent and wood protector composition has significant commercial potential in the wood treatment and construction industries, offering a more effective and efficient solution for controlling termites and protecting wood products. The new methods and systems for its application and use provide opportunities for expansion into new markets and industries.
