An insect control article to control flying insects. The insect control article has a non-absorptive and inert substrate that is coated 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, tefluthrin, and combinations thereof. The method of the invention for controlling flying insects includes providing an insect control article having a non-absorptive, inert substrate that is coated with an active insect control ingredient available for passive evaporation, wherein the active insect control ingredient is selected from the group consisting of transfluthrin, tefluthrin, and combinations thereof. The insect control article is then placed in an environment in such a manner that the substrate of the insect control article is exposed to non-augmented air movement, and the active insect control ingredient coated on the substrate is allowed to evaporate passively into the air.
