Abstract: Disclosed herein is a composition having an insect repellent compound, a strengthening polymer, and a compatibilizing polymer. The strengthening polymer is immiscible in the insect repellent compound at a temperature from 23° C. to 250° C. The compatibilizing polymer is miscible in the insect repellent compound at the temperature. Insect repellant materials, including fibers and films, may be made from the composition.

Abstract: A composition comprising a first insect repellent compound, a second insect repellent compound, and a polymer that is miscible in the first insect repellent compound at 23° C. The polymer is dissolved in the first insect repellent compound. An example first insect repellent compound is N,N-diethyl-meta-toluamide, and example second insect repellent compounds are nootkatone, permethrin, or transfluthrin.

Abstract: An insect repellent material made from recycled polyethylene terephthalate and an insect repellent or from polyethylene terephthalate, N,N-diethyl-meta-toluamide, and picaridin. The material may be in the form of a fiber spun from a solution of the recycled polyethylene terephthalate and the insect repellent.

Abstract: Disclosed herein is a composition having an insect repellent compound and a polymer that is miscible in the insect repellent compound at 23° C. Also disclosed herein is a method of: providing an insect repellent compound, providing a polymer that is miscible in the insect repellent compound at 23° C., and dissolving the polymer in the insect repellent compound to form a composition.

Abstract: In a method of attracting mosquitoes using a mixture of carbon dioxide and a mosquito attractant, the improvement of maximizing attraction by preventing or substantially minimizing absorption of moisture into the attractant that would distort the weight of the attractant left after effusion of attractant in a plume, comprising: a) regulating flow of CO2 through an inlet containing a desiccant into a confined chamber; b) allowing CO2 from step a) to admix with an attractant vapor emitted from a wick extending through an opening in an enclosed vial containing a liquid attractant in the confined chamber; c) emitting an admixture of desiccated CO2 and attractant as a plume through an outlet of the confined chamber to lure mosquitoes for a predetermined time; and d) weighing the amount of liquid attractant left in the enclosed vial to ascertain the amount of vaporous attractant emitted in the plume to ascertain the number of mosquitoes attracted per amount of attractant.
