Abstract: A film-forming bioactive composition for control of crawling insects and the like is disclosed. Also disclosed are methods of producing and utilizing the bioactive composition. The bioactive composition comprises a water-in-oil emulsion, a bioactive ingredient dispersed throughout the emulsion, and a lubricating agent also dispersed throughout the emulsion. The water-in-oil emulsion comprises a continuous phase, an aqueous discontinuous phase, and an emulsifier system for dispersing the discontinuous phase throughout the continuous phase. The bioactive composition of the present invention is characterized in that after particles of the instant bioactive composition have been applied to a surface, a substantial portion of the continuous and discontinuous phases will evaporate over time, leaving a residual film on the surface. Such film comprises the emulsifier system, the bioactive ingredient, and the lubricating agent.

Abstract: A water-soluble, foamable, insecticidally-active composition is disclosed. Also disclosed are methods for producing such a composition. The water-soluble, foamable, insecticidally-active composition comprises an aqueous phase, an insecticidally-active toxicant, and a foam-causing ingredient. The aqueous phase comprises water. The foam-causing ingredient must be capable of dispersing the insecticidally-active toxicant throughout the aqueous phase, to produce a toxicant-in-water dispersion. The foam-causing ingredient is present in an amount effective to enable the toxicant-in-water dispersion to form-in-place a water-soluble and insecticidally-active foam. The water-soluble aspect of the foam allows dissolving the foam (utilizing sufficient water) when desired.
