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. 11,856,954.

Background and Problem Solved

The original patent disclosed dual active insecticidal compositions, comprising transfluthrin and imiprothrin, which effectively knock down and kill both flying and crawling insects. However, these compositions had limitations, such as the need for residual kill agents and synergists, and the potential for reduced efficacy over time. The new invention addresses these limitations by introducing synergistic blends of polar, organic solvents, optimized ratios of active ingredients, and enhanced propellants, resulting in improved knockdown and kill efficacy, and reduced exposure to active ingredients.

Novelty and Inventive Step

The new claims introduce several novel and non-obvious features, including the use of synergistic blends of polar, organic solvents, optimized ratios of active ingredients, and enhanced propellants. These features provide a significant improvement over the original patent, addressing the limitations of residual kill agents and synergists, and achieving better knockdown and kill efficacy.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include using different polar, organic solvents, varying the ratios of active ingredients, or incorporating additional synergists. Variations of the dispensing device could also be explored, such as using different patterns or frequencies of release.

Potential Commercial Applications and Market

The invention has significant commercial potential in the pest control industry, particularly in the areas of household insecticides, agricultural pest control, and public health insecticides. The improved efficacy and reduced exposure to active ingredients make the invention an attractive solution for companies and consumers seeking more efficient and safer pest control options.
