Article for insert control by passive evaporation of an active ingredient
First Claim
1. A method for controlling flying insects comprising the steps of:
- a. providing an insect control article having a substrate with an essentially open surface that is impregnated with an active insect control ingredient in a structure such that the ingredient will passively evaporate when exposed to air to control the flying insects, wherein the active insect control ingredient is selected from the group consisting of transfluthrin, prallethrin, tefluthrin, and combinations thereof, and wherein the insect control article includes attaching means for attaching the impregnated substrate to means for circulating air;
b. placing the insect control article in an environment with air movement by attaching the insect control article to means for circulating air at a selected location not in contact with any fan blades thereof and exposing the open surface of the insect control article to air circulated by the means for circulating air, wherein the environment is selected from the group consisting of outdoor areas, sleeping areas, and rooms of not less than 27 m3; and
c. allowing the active insect control ingredient impregnated within the substrate to passively evaporate into the air in an environment free of added haet;
d. wherein the substrate of the insect control article is selected from the group consisting of paper-board, open pore cellulosic materials, coiled corrugated paper, woven cloth and non-woven pads or felts of fiber, gels, and absorbent solid-porous foams.

Abstract
An insect control article to control flying insects. The insect control article has a substrate that is impregnated with an active insect control ingredient that is available for passive evaporation. The active insect control ingredient is selected from the group consisting of transfluthrin, prallethrin, tefluthrin, esbiothrin, and combinations thereof. The method of the invention for controlling flying insects includes providing an insect control article having a substrate that is impregnated with an active insect control ingredient available for passive evaporation, wherein the active insect control ingredient is selected from the group consisting of transfluthrin, prallethrin, vaporthrin, teflurthrin, esbiothrin, DDVP, and combinations thereof. The insect control article is then placed in an environment with air movement in such a manner that the substrate of the insect control article is exposed to the air movement, and the active insect control ingredient impregnated within the substrate is allowed to evaporate passively into the air.
