Passive space insect repellant strip
First Claim
1. An insect control article to control flying insects, comprising a non-porous, non-absorbing substrate and a coating on said substrate of 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, and wherein solubility of the active insect control ingredient in the non-absorbing substrate is less than or equal to about 40 μ
- g/cm2 of substrate surface area, and the coating is formed by applying a solution of said active insect control ingredient and a solvent on said substrate, said solvent having a vapor pressure of less than or equal to 100 mm Hg and a Hansen'"'"'s hydrogen bonding parameter of less than or equal to 6.0, and thereafter removing said solvent to provide said active insect control ingredient at a dose level of from 2.4 μ
g/cm2 to 72 μ
g/cm2 of substrate surface area.

Abstract
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.
